Explaining the World Through Macroeconomic Analysis

overall conclusions about the relevance and significance of macroeconomics

When the price of a product you want to buy goes up, it affects you. But why does the price go up? Is demand greater than supply? Does the cost go up because of the raw materials needed to make it? Or, is it a war in an unknown country that affects the price?

To answer these questions, we need to turn to macroeconomics. Macroeconomic analysis provides a way to understand the world through studying the economy.

Key Takeaways

Macroeconomics is the branch of economics that studies the economy as a whole.
Macroeconomics focuses on three things: National output, unemployment, and inflation.
Governments can use macroeconomic policy including monetary and fiscal policy to stabilize the economy.
Central banks use monetary policy to increase or decrease the money supply, and use fiscal policy to adjust government spending.

What Is Macroeconomics?

Macroeconomics is the study of the behavior of the economy as a whole. This is different from microeconomics, which concentrates more on individuals and how they make economic decisions. While microeconomics looks at single factors that affect individual decisions, macroeconomics studies general economic factors.

Macroeconomics is very complicated, with many factors that influence it. These factors are analyzed with various economic indicators that tell us about the overall health of the economy.

The U.S. Bureau of Economic Analysis provides official macroeconomic statistics.

Macroeconomists try to forecast economic conditions to help consumers, firms, and governments make better decisions:

Consumers want to know how easy it will be to find work, how much it will cost to buy goods and services in the market, or how much it may cost to borrow money.
Businesses use macroeconomic analysis to determine whether expanding production will be welcomed by the market. Will consumers have enough money to buy the products, or will the products sit on shelves and collect dust?
Governments turn to macroeconomics when budgeting spending, creating taxes, deciding on interest rates, and making policy decisions.

Macroeconomic analysis broadly focuses on three things—national output (measured by gross domestic product), unemployment, and inflation.

Gross Domestic Product (GDP)

Output, the most important concept of macroeconomics, refers to the total amount of goods and services a country produces, commonly known as the gross domestic product (GDP) . This figure is like a snapshot of the economy at a certain point in time.

When referring to GDP, macroeconomists tend to use real GDP , which takes inflation into account, as opposed to nominal GDP , which reflects only changes in price. The nominal GDP figure is higher if inflation goes up from year to year, so it is not necessarily indicative of higher output levels, only of higher prices.

The drawback of GDP is that information has to be collected after a specified time period has passed. Therefore a figure for the GDP today would have to be an estimate.

GDP is nonetheless a stepping stone into macroeconomic analysis. Once a series of figures is collected over a period of time, they can be compared, and economists and investors can begin to decipher business cycles, which are made up of the periods alternating between economic recessions (slumps) and expansions (booms) that occur over time.

From there we can begin to look at the reasons why the cycles took place, which could be government policy, consumer behavior, or international phenomena, among other things. Of course, these figures can be compared across economies as well. Hence, we can determine which foreign countries are economically strong or weak.

Based on what they learn from the past, analysts can then begin to forecast the future state of the economy. It is important to remember that what determines human behavior and ultimately the economy can never be forecasted completely.

The Unemployment Rate

The unemployment rate tells macroeconomists how many people from the available pool of labor (the labor force) are unable to find work.

Macroeconomists agree when the economy witnesses growth from period to period, which is indicated in the GDP growth rate, unemployment levels tend to be low . This is because, with rising (real) GDP levels, we know the output is higher and, hence, more laborers are needed to keep up with the greater levels of production.

The third main factor macroeconomists look at is the inflation rate , or the rate at which prices rise. Inflation is primarily measured in two ways: the Consumer Price Index (CPI) and the GDP deflator. The CPI gives the current price of a selected basket of goods and services that is updated periodically. The GDP deflator is the ratio of nominal GDP to real GDP.

If nominal GDP is higher than real GDP, we can assume the prices of goods and services have been rising. Both the CPI and GDP deflator tend to move in the same direction and differ by less than 1%.

Demand and Disposable Income

What ultimately determines output is demand . Demand comes from consumers, from the government, and from imports and exports.

Demand alone, however, will not determine how much is produced. What consumers demand is not necessarily what they can afford to buy, so to determine demand, a consumer's disposable income must also be measured. This is the amount of money left for spending and/or investment after taxes.

Disposable income is different from discretionary income, which is after-tax income, less payments to maintain a person's standard of living.

To calculate disposable income, a worker's wages must be quantified as well. Salary is a function of two main components: the minimum salary for which employees will work and the amount employers are willing to pay to keep the employee. Given that demand and supply go hand in hand, salary levels will suffer in times of high unemployment, and prosper when unemployment levels are low.

Demand inherently will determine supply (production levels) and an equilibrium will be reached. But in order to feed demand and supply, money is needed. A country's central bank (the Federal Reserve in the U.S.) typically puts money in circulation in the economy. The sum of all individual demand determines how much money is needed in the economy. To determine this, economists look at the nominal GDP, which measures the aggregate level of transactions, to determine a suitable level of the money supply .

What the Government Can Do

There are two ways the government implements macroeconomic policy. Both monetary and fiscal policy are tools the government uses to help stabilize a nation's economy. Below, we take a look at how each works.

Monetary Policy

A simple example of monetary policy is the central bank's open market operations . When there is a need to increase cash in the economy, the central bank will buy government bonds (monetary expansion). These securities allow the central bank to inject the economy with an immediate supply of cash. In turn, interest rates—the cost to borrow money—are reduced because the demand for the bonds will increase their price and push the interest rate down. In theory, more people and businesses will then buy and invest. Demand for goods and services will rise and, as a result, the output will increase. To cope with increased levels of production, unemployment levels should fall and wages should rise.

On the other hand, when the central bank needs to absorb extra money in the economy and push inflation levels down, it will sell its Treasury bills , or T-bills. This will result in higher interest rates, which will cause less borrowing, less spending, and less investment. It will also decrease demand, which will ultimately push down the price level (inflation) and result in less real output.

Fiscal Policy

The government can also increase taxes or lower government spending in order to conduct a fiscal contraction . This lowers real output because less government spending means less disposable income for consumers. And, when more of a consumer's wages go to taxes, demand will also decrease.

A fiscal expansion by the government would mean taxes are decreased or government spending is increased. Either way, the result will be growth in real output because the government will stir demand with increased spending. In the meantime, a consumer with more disposable income will be willing to buy more.

A government will tend to use a combination of both monetary and fiscal options when setting policies that deal with the economy.

What Are the Key Macroeconomic Indicators?

The key macroeconomic indicators are the gross domestic product, the unemployment rate, and the rate of inflation.

What Is the Purpose of Macroeconomic Analysis?

Macroeconomic analysis allows a country to monitor its economic health, develop sound policies and practices, and sustain suitable growth.

How Does the Government Influence Macroeconomics?

The two main ways a government can influence macroeconomics is through monetary policy and fiscal policy. Monetary policy helps control the flow and quantity of money in an economy while fiscal policy uses government spending and taxation to influence economic conditions.

The Bottom Line

The performance of the economy is important to all of us. We analyze the economy by primarily looking at the national output, unemployment, and inflation. Although it is consumers who ultimately determine the direction of the economy, governments also influence it through fiscal and monetary policy.

In this chapter we have looked at indicators of macroeconomic activity and performance, and the measurement of macroeconomic activity using the national accounts. We have not examined the conditions that determine the level of economic activity and fluctuations in that level. An economic model is required for that work. In the next chapter we introduce the framework of a basic macroeconomic model.

Key Concepts

Macroeconomics studies the whole national economy as a system. It examines expenditure decisions by households, businesses, and governments, and the total flows of goods and services produced and incomes earned.

Real Gross Domestic Product (GDP) , prices and inflation rates , and employment and unemployment rates are indicators of macroeconomic activity and performance.

Fluctuations in the growth rate of real GDP, in inflation rates, and in unemployment rates are important aspects of recent economic performance in Canada.

The expenditures by households, production of goods and services by business, and the incomes that result are illustrated by the circular flow of real resources and money payments.

The National Accounts provide a framework for the measurement of the output of the economy and the incomes earned in the economy.

Nominal GDP measures the output of final goods and services at market prices in the economy, and the money incomes earned by the factors of production.

Real GDP measures the output of final goods and services produced, and incomes earned at constant prices.

The GDP deflator is a measure of the price level for all final goods and services in the economy.

Real GDP and per capita real GDP are crude measures of national and individual welfare. They ignore non-market activities, the composition of output, and the distribution of income among industries and households.

Two themes dominated the discussions at the seminar. How do macroeconomic policies and the environment interact? How important is it that the Fund staff become aware of this interaction and take it into account in dealing with member countries?

Sessions 1, 2, and 3 of the seminar were devoted mainly to the first theme, while Session 4 focused primarily on the second theme. The seminar opened with welcoming remarks, which provided to the participants the background of Fund work on the environment, and closed with concluding remarks, which, among other things, looked forward to establishing priorities for Fund work on the environment.

In her welcoming remarks, Margaret Kelly reminded participants that the primary mandate of the Fund is to promote international monetary cooperation and exchange rate stability and to help member countries solve their balance of payments problems. Nevertheless, should resource depletion or environmental damage in a country be so severe as to affect seriously the longer-term viability of its balance of payments, the IMF staff cannot but be involved. Kelly described how Fund staff work on the environment has so far focused on monitoring the research of other specialized institutions and developing an understanding of the links between macroeconomic policies and conditions and the environment—thereby enabling the staff to design sound macroeconomic policies.

Interrelationships Between Macroeconomics and the Environment

In dealing with links between macroeconomics and the environment, the first three sessions of the seminar reviewed the conclusions of readily available studies using alternative analytical frameworks (Session 1), the urgency and feasibility of integrating the environment into national accounts (Session 2), and case studies of the possible impact on the economy of integrating environmental objectives into macroeconomic policymaking (Session 3).

Impact of Macroeconomics on the Environment

The Ved Gandhi and Ronald McMorran paper highlighted four conclusions that have been reached by the analyses carried out in the partial equilibrium framework. First, macroeconomic stability is a minimum and necessary condition for preserving the environment. Second, environmental degradation is generally caused by market, policy, and institutional failures relating to the use of environmental resources. Third, macroeconomic policies can have an adverse impact on the environment but only when market, policy, and institutional failures exist, although it is difficult in advance to judge how serious these impacts will be. Fourth, macroeconomic policies are inefficient and blunt instruments for mitigating environmental degradation, for which appropriate environmental policies are the most efficient and direct instruments. The authors conclude that only general equilibrium analyses, carried out with the help of computable general equilibrium (CGE) models, can help one reach country-specific conclusions on how the country’s macroeconomic policies, or their reform, are likely to affect the environment.

The Stein Hansen paper begins where the Gandhi and McMorran paper leaves off. Using examples of the research work done in Norway and in the United States, it highlights many advantages of CGE modeling, which, among other things, can help to (1) establish the loss of GDP and the reduction in its growth rate owing to environmental policies aimed at reducing CO 2 and SO 2 emissions, (2) permit policymakers see the direct and indirect consequences for the macroeconomy of alternative uses of revenues from environmental taxes, such as a CO 2 stabilizing gasoline tax, and (3) bring together policymakers (from ministries of finance and economy and the ministry of environment) for a professional and political dialogue and make them recognize the tradeoffs between pursuing alternative macroeconomic and environmental objectives. Hansen also shows (giving the examples of higher stumpage fees and raising the wage rate in Costa Rica) how sometimes general equilibrium results can be quite opposite from the partial equilibrium results. He recognizes that CGE models require lots of reliable data and assumptions, which not all countries have, and certainly most developing countries do not have.

Much like the Gandhi and McMorran conclusions, Hansen points out partial equilibrium impacts of fiscal discipline, exchange rate and trade liberalization, interest rate and credit policy reform, and external debt relief, especially in developing countries. These can be both negative and positive at the same time, depending upon environmental policies, and can in the end yield “uncertain” final outcomes. Nonetheless, he suggests that macroeconomic policies of developing countries would greatly improve the environment if the following measures were undertaken: (1) avoid reducing small and fragile environmental and health care budgets, (2) curtail fertilizer, pesticide, water, and energy subsidies, (3) restructure health budgets from capital-intensive curative hospitalization to labor-intensive preventive primary health care, (4) include land-reform and property-right measures in the reform program in order to facilitate internalizing the environmental externalities resulting from malfunctioning land markets, (5) increase taxes and lower subsidies that affect forests and other natural resources, and (6) ensure that external debt relief is not used to finance environmentally harmful projects.

Andrew Steer, in commenting on both papers, agreed with their overall conclusions that the impact of macroeconomic policy reforms on the environment is generally positive. He highlighted the four paths through which this comes about. First, macroeconomic instability promotes high discount rates and short-term calculations, guaranteeing environmental destruction through excessive natural resource exploitation and deforestation, while macroeconomic stabilization encourages environmentally sound decisions by economic agents. Second, although a curtailment of aggregate demand in theory helps the environment through less consumption, less depletion, and less waste, cuts in environmental public expenditures (as a part of a reduction in public expenditures to reduce fiscal imbalances) in certain cases may be detrimental to protecting the environment. Third, macroeconomic policy reforms affect the environment through relative price shifts. Most of these impacts, especially those which move the economy from subsidized input prices toward world prices, help improve the quality of the environment. However, as Hansen and Gandhi and McMorran point out, the impact will also depend on a number of features of the economy, especially whether or not complementary “first-best” environmental policies exist. Fourth, structural reforms relating to financial sector, accountability of state-owned enterprises, property rights, and the like, often associated with macroeconomic adjustment programs, also promote economic efficiency and reduce waste. As with relative price shifts, for structural reforms to work for sustainable development and not against it, certain preconditions must exist. As an illustration, privatization can easily become a cause for air and water pollution if environmental policies are absent or civil society is weak and lacks empowerment.

Steer also agreed with Hansen that, based on the simulations of CGE models in Norway and the United States, radical environmental policies may not greatly reduce the rate of economic growth in industrial countries. Whether or not the public is ready and willing to accept even that much reduction is another matter.

In the discussion that followed, there was support for the general equilibrium approach and CGE modeling. It was pointed out, however, that with a suitable choice of parameters one can get any result that one wants, and that these models were less useful in generating specific numbers and more useful in supplementing other tools to develop broad trends. On the whole, development of CGE models was not seen as a priority for the use of limited resources in developing countries.

Developing sectoral policies and implementing them effectively were recognized as important for the overall impact of macroeconomic policies on the environment. Given that these sectoral policies had significant feedbacks, a commentator argued that the Fund cannot absolve itself of the responsibility of taking these policies into account. However, there was also a consensus that macroeconomic policy reform was too critical to wait until sectoral policies have been properly designed or effectively implemented.

Ecotaxes were underscored as an important element of environmental policies. The scope for such taxes to replace distortionary income taxes and regressive value-added taxes was explored. Because a tax system must meet the criteria of efficiency, equity, and revenue productivity, it was felt that ecotaxes should supplement, rather than replace, existing broad-based taxes.

One participant stressed the importance of social structures to the environment and the impact of macroeconomic policies on social structures. Although it was argued that the Fund should recognize the importance of social structures in its operational work, the consensus was that because the World Bank had the necessary expertise in matters relating to social structures, the Fund should utilize the knowledge and expertise of the Bank staff in this regard.

It was emphasized that natural resources in many developing countries were exploited excessively because of a nontransparent system of rent-seeking by vested groups and that the Fund staff should therefore encourage a greater transparency in leasing of exploitation rights.

Finally, it was questioned whether strong environmental policies were compatible with an acceptable level of macroeconomic performance.

Here, the general feeling was that reasonably (but not excessively) strong environmental policies may mean some reduction in the level and growth rate of GDP, conventionally measured, but that outcome should not be considered intolerable. The Norwegian simulations, given as major evidence of this conclusion, had broad support.

Impact of the Environment on Macroeconomy

David Pearce and Kirk Hamilton stressed the impact of pollution and environmental degradation on the macroeconomy, in the first instance through its impact on human capital. They argued and provided evidence that air pollution, caused mainly by a weak transportation policy for fuel conservation and vehicular traffic, often resulted in ill health and premature mortality. Similarly, they argued that a lack of water-treatment facilities led to contamination of water and caused many waterborne diseases.

They further argued that investments in environmental protection, which often had high rates of return and benefits even in terms of conventionally measured GNP, are often ignored in macroeconomic analysis. An example of such investments was afforestation, which could help improve soil fertility and crop yields, increase timber production and other tree products, and produce forest fodder. Such investments, of course, will also have nonmarket returns in the form of biological diversity and carbon storage.

Pearce and Hamilton then took up the issue of depletion of natural resources and degradation of the natural environment (or natural capital) which can have a significant impact on economic welfare and macroeconomy through erosion of what they call the “genuine savings rate.” They felt that the concept of “genuine savings rate,” defined as [GNP-Consumption-Depreciation of produced capital] - [value of “net” depletion of natural resources] - [marginal social cost of “net” accumulation of pollution], is the most relevant way to assess the impact of depletion of natural resources and pollution of the environment on economic welfare and the sustainability of the macroeconomy. In fact, they showed that an economy can have a positive conventionally measured savings rate, derived from conventionally measured national accounts under the system of national accounts (SNA), but a negative genuine savings rate. They emphasized that an economy will be unsustainable and economic welfare will eventually decline, if a negative genuine savings rate persists. Hence, they suggested that only those policy reforms should be implemented that will not only enhance the SNA-based savings rate but will curtail losses resulting from natural resource depletion and environmental pollution.

The authors made heroic attempts to estimate the genuine savings rates for various parts of the world. These estimates reveal that the Middle East and North Africa have negative genuine savings rates; in Latin America and the Caribbean, they have turned from positive to negative in recent years; and in most sub-Saharan African countries, they are consistently negative, holding a serious potential for the unsustainability of their economies.

Pearce and Hamilton therefore concluded with a call for revised economic accounting, for the development of better valuation techniques of nonmarketed natural and environmental resources, and for the Fund in particular to revise its savings and other macroeconomic indicators to incorporate sustainability considerations.

Kirit Parikh, who commented on the Pearce-Hamilton paper, had little difficulty with the authors’ urging that the countries should have a proper transport policy (to curb air pollution) and investments in water treatment (to improve water quality), but found three major flaws in the concept of genuine savings rate. First, in adding man-made physical capital to natural capital, the authors assume a one-to-one substitutability between the two, which is inappropriate. Second, the concept of a genuine savings rate refers strictly to the domestic economy and ignores the environmental damage done elsewhere when a country imports pollution—and natural—resource-intensive products from elsewhere. Third, the authors do not deduct the losses of global commons caused by the lifestyle of a country; as a result, the U.S. economy, for example, comes out being “sustainable” by their criteria.

In the discussion that ensued, the participants noted alternative approaches to the concern for the environment—an all-out approach of the Norwegian kind, in which environmental targets are agreed to with the NGOs and macroeconomic policies are made subject to those constraints, and an incremental approach along the Pearce-Hamilton lines, under which the negative impact of macroeconomic policies on the environment is measured through some index, like the genuine savings rate. Which approach is more suitable for the Fund staff to pursue? While not fully resolved, the latter approach appeared pragmatic and feasible at this stage, since it essentially required the Fund staff to focus on how macroeconomic adjustment was achieved and what its effect was on some index of sustainability.

One participant reminded the seminar that the Fund staff, which did medium-term balance of payments projections, did consider the longer-term sustainability of natural resources, to the extent that the impact of the exhaustion of exportable resources on the medium-term macroeconomic outlook was of serious concern to the Fund. However, environmental economists present wanted the Fund staff to go even further and start looking at the erosion of soil and other environmental resources, which may not necessarily affect the medium-term outlook of exports, but were important to the sustainability of macroeconomic performance, economic welfare, and quality of life.

Another participant reminded the seminar that the concept of sustainability was still not fully defined. What the policymakers should aim at was unclear. Was it sustainability? Over what period? Would environmental damage over the short to medium term be acceptable if it was reversible and helped countries improve their financial and economic situation in the short run, which provided resources to pay for the cost of reversing the damage in the medium to long run? The answer seemed to be yes.

A question was whether there were trade-offs between the rate of macroeconomic adjustment (macroeconomic objectives) and the rate of environmental protection (environmental objectives). Here, the answer was probably yes. However, it was not clear how far macroeconomic adjustment should be forgone in the interest of environmental protection.

Feasibility of Environmentally Adjusted National Accounts

The Adriaan Bloem and Ethan Weisman paper, as presented by Paul Cotterell, recognized the importance of “green” and “brown” accounts for raising public awareness of environmental issues and toward an understanding of interrelationships between macroeconomy and the environment. However, of the two possible approaches—the physical approach (which would involve the measurement of physical data on natural resources and pollution) and the monetary approach (which would require monetary values associated with the physical data)—they preferred the physical approach as the first step. In their opinion, this approach abstracts from “correct” prices while the monetary approach would require valuations and estimations based upon a variety of sensitive assumptions and modeling of economic behavior.

Bloem and Weisman pointed out that the traditional measures of national accounts aggregates should not be replaced by green national accounts, but that a supplementary set of satellite accounts should be developed as recognized by the 1993 SNA. However, Bloem and Weisman also recognized that the satellite accounts were “a work-in-progress” and that further research and experience would be needed to develop fully these satellite accounts to integrate the entire financial accounts, the rest of the world account, and the balance sheets. Practical experience with this approach in the United States and the Netherlands provided adequate support for staying with this approach at this stage. Even this approach would require physical data on the environment, which were not always available and whose generation in itself would represent substantial progress.

Peter Bartelmus in emphasized his paper the significance and need for environmentally adjusted national accounts. He quoted the studies on Mexico and Papua New Guinea to show how results and conclusions on growth rates of the economy can vary significantly whether unadjusted or adjusted national accounts were used. He stressed how environmentally adjusted national accounts can facilitate modeling and creation of data relevant for policy analysis for sustainable development. Finally, he suggested that “valuation” of natural resources, notably through maintenance costing of the use of environmental assets can help in full-cost pricing and therefore in the internalization of environmental costs. But he also recognized the many problems and limitations of developing environmentally adjusted national accounts and using them to assess sustainability in growth and development. There are conceptual and statistical difficulties in defining and measuring social (human and institutional) capital. Even with respect to environmental capital, serious problems exist in relation to valuing the environmental services or estimating the depletion and depreciation of environmental assets. Bartelmus, however, felt that techniques designed to overcome data and definitional problems did exist and had been successfully applied in several country case studies.

Bartelmus also argued that integrated environmental-economic accounts can help see the sustainability of economic growth in terms of positive trends of environmentally adjusted net domestic product (EDP). The definition and measurement of a broader concept of sustainable development, on the other hand, would require supplementary physical indicators as, for instance, developed in Frameworks for Indicators of Sustainable Development.

The System of integrated Environmental and Economic Accounting (SEEA), proposed by the United Nations, is based on the revised 1993 SNA. It attempts to measure the sustainability of economic growth in terms of the costs of maintaining both produced and natural assets. Welfare-oriented approaches to national accounts would require the removal from GDP of the so-called “defensive expenditures,” needed to mitigate the effects of pollution. However, both the definition and the elimination of defensive expenditure from accounting aggregates are controversial and inconsistent with conventional economic indicators. The SEEA, therefore, identifies environmental protection expenditures as part of intermediate and final use and only by appropriate classifications.

Bartelmus concluded that the macroeconomy-environment interactions can be studied at this stage by means of “satellite” accounts, parallel to conventional national accounts, without replacing the core accounts of the SNA by environmental ones. He also described the advantages of an integrated information system such as the SEEA. In this context, he indicated a number of direct policy uses of the results of integrated accounting, notably the setting of economic instruments at maintenance cost levels (at the microeconomic level), and the use of environmentally adjusted indicators such as capital (including natural capital), capital accumulation, environmental cost of depletion and degradation, and adjusted aggregates of final consumption and trade (at the macroeconomic level). Bartelmus pleaded for international cooperation to standardize concepts and methods of environmental accounting for worldwide use and application.

Michael Ward, who commented on both papers, noted that neither Bloem and Weisman nor Bartelmus showed exuberance for a fully integrated and comprehensive environmental accounting system. The former take this position because such accounts have many intractable and systemic measurement problems with limited relevance to fiscal and monetary management and the development of overall macroeconomic strategy. The latter believes that the ultimate objective of sustainability should be sustainability of people and their welfare rather than of the economy alone. Ward recapitulated two serious difficulties with an integrated accounting framework. First, there was the issue relating to the quantities—industrial production generates environmentally degrading outputs, such as polluting effluents, wastes, and energy losses, but technological changes can convert such “dirty” residual outputs into “clean” outputs. It was unclear how one should take account of such quantities. Second, there were many issues relating to valuation and pollution. What were the “appropriate” prices, given the ill-conceived interventions by governments, income and wealth inequalities, and intergenerational factors that shape social and economic policies? How should one “price” cross-border environmental externalities? How should one deal with different “valuations” that countries at different stages of development are bound to apply to environmental damage? How to “value” a natural resource being exploited by a multinational monopoly for which competitive markets did not exist? How to know that external costs have not been internalized already into “prices”? Thus, Ward also considered integrated environmental accounting unachievable until the relevant conceptual, methodological, and statistical issues had been resolved.

Nevertheless, he advised that policy practitioners at the Fund and the World Bank can still take certain initiatives. The Fund can remain a macroeconomic organization but can ensure sustainability through an insistence on “green taxes” in its operational work, so that countries achieve a more balanced and rational pattern of progress. The World Bank, on the other hand, should ensure that, at a minimum, all countries have an adequate provision of safe water, solid waste disposal, and clean sanitation, which are the key environmental issues everywhere. The Fund staff could then ensure that government expenditures and investments in these services would be protected from cuts in public outlays following a fiscal stringency. Ward also called on the World Bank to help enhance institutional capacity for environmental protection and, as a start, assess the importance to future development of “big ticket” items of resource depletion and ecological deterioration in a dozen selected developing countries.

The discussion that followed supported the general conclusion that while it would be desirable to have environmentally integrated national accounts, for short-term macroeconomic policy formulation conventional national accounts would suffice. Only one discussant felt that conventional national accounts, especially in economies heavily dependent on natural resources, would send out wrong signals on savings, investments, and balance of payments.

There was also a general agreement, that given serious conceptual and methodological issues, the approach that the 1993 SNA has taken, of creating satellite accounts, was quite acceptable at this stage. Efforts to resolve the serious outstanding issues must nevertheless continue.

Integrating Macroeconomics and the Environment—Industrial Country Experience

Knut Alfsen describes in his paper how Norway, a small industrial country, has attempted to integrate environmental concerns into its macroeconomic policymaking.

Historically, because natural resources have been important to the Norwegian economy (most important among all OECD countries except for Ireland) natural resource accounting (for energy, fishing, land use, sand, and gravel) was the first step the authorities took, some 20 years ago, primarily to improve long-term conservation and resource management. The accounts consisted of reserves, extraction rates, and domestic end uses, and, in the context of energy accounts, air pollution emission. However, the authorities used only energy accounts information actively (as energy was an input into production and energy output was important to the economy) and integrated this information into macroeconomic modeling.

More recently, however, the coverage of resource and environmental accounts has been broadened. In addition, environmental assets and environmental degradation have been linked to the economic productivity of capital and labor; as a result, the macroeconomic model used in policy formulation has become more versatile. It now contains energy use and associated emissions of nine polluting compounds, generation of various types of wastes, physical effects of air pollution and waste generation, and economic valuation of environmental degradation based on shadow prices of capital and labor. Alfsen pointed out the many questions the authorities have sought to answer with the help of the integrated model. These have included determining the costs in GDP terms (net of indirect gains to the GDP) of meeting targets set in international treaties and protocols and comparing costs in GDP terms associated with meeting environmental targets (i.e., increase in pollution) with those that would accrue if no environmental targets were set. Alfsen admits, however, that the Norwegian model depends heavily on many assumptions and ignores the links between employment and the environment.

Alfsen describes how the model has been used in Norway to identify the economic and environmental effects of introduction of carbon taxes, the decline in emissions (or emission elasticity) when fuel and electricity prices are raised, and the costs to specific sectors of the economy of specific environmental policies.

According to Alfsen, important policy conclusions have been derived from such analyses. On carbon taxes : (1) These are not the most efficient means of reducing NO x emissions. (2) Since national targets of emissions and pollution are unachievable even with high carbon taxes, other measures need to be taken as well. (3) Secondary economic effects of introducing carbon taxes are highly uncertain. (4) Loss of GDP estimates owing to carbon taxes vary with varying assumptions. On emission elasticity : (1) Elasticities depend greatly on the assumptions made. (2) Transport activities have the greatest impact on pollution and the greatest sensitivity for emissions. (3) Energy and capital are complementary inputs and taxation of sulphur emissions reduces long-term economic growth. As to the impact on individual sectors , taxation is found to be the most cost-effective means in Norway for lowering emissions from polluting sectors.

In analyzing why Norway has been successful in integrating environmental concerns into macroeconomic policy formulation, Alfsen could provide only a tentative answer: because of economic, political, and institutional factors. The main economic factor is the importance of natural resources to the society and how they are managed. The main political factor is that organized political groups, including the NGOs, that depend on government funds have supported politicians responding to their needs and objectives. The long experience of Statistics Norway, first with natural resource accounting and later with modeling integrated national accounts for policy formulation purposes, has encouraged dialogue between relevant institutions and actors in the debate. In addition, the Ministry of Finance has come to see environmental taxes as a way of expanding the tax base. These are the peculiar institutional factors. Alfsen is not sure if the Norwegian experience with integrating environmental considerations into macroeconomic policymaking can be replicated in other countries, but he believes that, if properly carried out, it can help break the power of vested interest groups.

Peter Clark, commenting on the Alfsen paper, drew from the Norwegian experience four lessons that he thought could be useful to other industrial countries. First, a model-based integration of environmental and macroeconomic policies facilitates consensus building by resolving differences in opinions and preconceived notions. Second, it places environmental concerns at the center of macroeconomic policymaking. Third, it helps analyze the feasibility of applying major environment policy shocks to the economy. Fourth, it helps identify both direct and indirect effects and nets them out.

Clark also had a few specific questions on Alfsen’s paper: Are there any alternatives to carbon taxes if they are considered inefficient means of reducing NO x ? By assuming that technology is exogenous, thereby denying technological progress, and by assuming that an energy tax is basically a tax on capital, does the model exaggerate the output losses owing to CO 2 taxes? How serious are the employment effects of environmental policies, such as the carbon tax? While Clark agreed that the production of power through hydroelectricity results in little pollution, it does make the country vulnerable to shocks in world prices of oil, which is the alternative form of fuel for energy production. Have the authorities paid attention to these consequences? All in all, Clark believed that that country’s experience held the prospects of wider applicability.

Alfsen’s paper generated much enthusiastic discussion among participants and raised several questions. Must conventional GDP losses result from environmental policies and can they be offset? What are the economic and distributional consequences of carbon taxes and other green taxes? How does the Norwegian CGE model integrate natural resources into the macroeconomy? Are integrated national accounts appropriate for international comparability? Has the monopoly in modeling by Statistics Norway in any way been hazardous, and has it done any damage to policymaking in Norway?

In his reply, Alfsen agreed that there are bound to be, and have been in Norway’s case, some costs to the economy of environmental policies and nobody can foresee whether technological changes will help to reduce these costs. In fact, nobody can foresee the nature and direction of technological change over time. Environmental policies, including eco-taxes, need not have crushing effects on economies, if their revenues are utilized wisely. The distributional consequences of such taxes and policies, however, may not be positive, especially in developing countries where income and wealth distribution is already heavily skewed.

Alfsen agreed that modeling oil and gas is not easy and, in the Norwegian CGE model, the natural resources are largely treated exogenously. He also agreed that integrated national accounts are necessary for international comparability, but not necessarily for the conduct of a domestic policy dialogue. As to the final question, Norway does have a Model Forum, where the shortcomings of various models are continuously discussed, so that the model of Statistics Norway is used after a consensus has been reached. In fact, it is because of the CGE model that the preconceived notion of the NGOs, that all economic growth is bad for the environment, has been corrected.

In connection with environmental taxes, a discussant made the point that, in addition to being supportive of environmental objectives, such taxes can provide finances for reducing the distortionary taxes on labor and capital and can help improve economic efficiency and prospects for economic growth. Environmental taxes were therefore seen as a true win-win policy for the environment as well as the macroeconomy.

Integrating Macroeconomics and the Environment—Developing Countries

Few developing countries have integrated their environmental objectives and policies with their macroeconomic objectives and policies; many still do not have clear-cut objectives and strategies for environmental protection. Therefore, little is known by way of experience. The country case studies carried out in the World Bank, however, throw much light on what would happen in developing countries if macroeconomics and the environment were integrated.

Mohan Munasinghe and Wilfrido Cruz summarized the main conclusions of recent World Bank case studies. These conclusions are in line with those in the Gandhi and McMorran paper, but the World Bank authors provide abundant evidence for their conclusions. For example, exchange rate reform is seen to be helpful to the environment by correcting the prices of tradables, encouraging wildlife protection and discouraging cattle ranching (in Zimbabwe and Zambia), providing incentives to protect nature preserves and game parks (in Tanzania), and helping expand the forests, and reduce land degradation and losses from floods (in Vietnam).

Pricing and subsidy reform in relation to electricity is shown to have a favorable impact on the environment because of energy conservation and improvements in air quality resulting from a reduction of electricity subsidies (in Sri Lanka) and rangeland improvement resulting from the reduction of livestock subsidies (in Tunisia). Reduction of price distortions and corrections of price signals are shown by the authors as creating significant benefits for the macroeconomy as well as for the environment.

High and unstable interest rates are shown to be detrimental to farm productivity over the longer run (in Brazil), while low and stable interest rates have had a welcome positive influence in curtailing the rate of logging (in Costa Rica).

The case studies also reveal how the beneficial effects of macroeconomic policy changes would have been much greater if complementary environmental policies had been in place. Munasinghe and Cruz emphasize that while the overall benefits of trade liberalization were positive—by promoting exports and encouraging industrialization—they were eroded in certain countries because the relative price changes brought about changes in the structure of production that had undesired side effects on the environment and that were not corrected by appropriate environmental policies. For example, trade liberalization promoted a water-intensive crop, such as sugarcane (in Morocco), that should have been discouraged by raising water charges. It encouraged a surge of (dirty) processing industries (in Indonesia) that could have been curbed by pollution regulations. It encouraged pressure on land resources and increased encroachment on marginal land as well as soil erosion (in Ghana) that could have been constrained by establishing property rights. The case studies of Mexico, Poland, and Thailand were mentioned as evidence of the extreme importance of building institutional capacity in developing countries that would help authorities foresee the undesired effects of macroeconomic reform and adopt appropriate corrective environmental measures.

Basing their arguments on the case studies, Munasinghe and Cruz point to the potential of fiscal cutbacks to damage the environment. Cutbacks in environmental expenditures, though insignificant to begin with, were shown to be environmentally unfriendly (in Thailand, Mexico, Cameroon, Zambia, and Tanzania) while cutbacks in the purchasing power, coupled with population growth, led to deforestation and cultivation of marginal lands (in the Philippines and Cameroon and certain other countries of sub-Saharan Africa).

The point made earlier by Hansen that partial equilibrium results can be misleading in certain circumstances is reconfirmed by Munasinghe and Cruz. In Costa Rica’s case, an increase in minimum wages was found to increase deforestation. Directly, it encouraged unskilled workers to move to cities (thus reducing deforestation), but indirectly investors found minimum wage legislation binding in the industrial sector and sought refuge in the agricultural sector (thereby increasing deforestation). The net result was increased conversion of forest land to farming.

Munasinghe and Cruz conclude from the World Bank case studies that economy-wide policies tend to have significant and important effects, but if environmental policies do not exist, there is no assurance that efficiency-oriented economic reforms will be beneficial to the environment. They believe that developing countries have substantial scope for implementing the right environmental policies and suggest a step-by-step approach to integrate the environment into macroeconomic policy formulation at the country level. Toward this, they regard the Action Impact Matrix proposed by them as a versatile analytical tool.

Cielito Habito, in commenting on the paper, agreed with Munasinghe and Cruz that the impact of macroeconomic reforms (and structural adjustment programs) was generally beneficial for the environment and that complementary environmental policies were needed to guard against or mitigate their adverse effects on the environment.

Taking the case of the Philippines, Habito illustrated how the economy-wide policies adversely affected the environment as the environmental policy framework was weak to nonexistent. There was a depletion of forest resources (and soil erosion owing to deforestation), as well as depletion of fisheries, as macroeconomic reforms turned the terms of trade against agriculture and farmers resorted to extensive farming and engaged in overfishing to make up for the loss of income. This process was facilitated by unduly low stumpage fees and liberal licensing rules. The air pollution also grew, owing to the anti-agriculture and pro-industry bias of macroeconomic reforms, as industries enjoyed excessive industrial protection provided by the Government. Water pollution became a serious problem, especially in cities, as public spending on water and sanitation facilities and garbage collection services was grossly inadequate. This pollution was exacerbated by migration from the country to the cities. In the Philippine case, Habito considers the anti-agriculture and pro-industry bias of macroeconomic reforms to be the major culprit.

But he also recognizes that the Philippines needs jobs, incomes, and industries to support her growing population, and that polluting industries may have been accepted because of their backward linkages with agriculture. Habito thus brought forth the trade-off between incomes and jobs and environmental concerns that the authorities of developing countries often face and for which the adoption of complementary environmental policies are absolutely indispensable. Once implemented, these policies have feedback effects on the economy and the prospects of economic growth that should also be taken into account.

Finally, Habito questioned the usefulness of the Action Impact Matrix proposed by Munasinghe and Cruz. Where conditions are changing rapidly and many factors and policies simultaneously affect the environment, he argued that the Matrix is bound to have an extremely limited usefulness. It will also be difficult to use it in practice owing to various constraints, including the paucity of data and analytical tools to balance the conflicting impacts.

In the discussion that followed, one discussant asked if, by stressing the importance of complementary policies, the World Bank and the Fund simply wish to treat the environmental protection as an add-on objective instead of fully integrating it into macroeconomic policy formulation. Another discussant asked Cielito Habito if it were at all possible that the staff of international organizations would ever be able to convince the authorities of developing countries to adopt politically sensitive environmental policies. Another question that was raised related to the emphasis on win-win policies resulting from subsidy reductions and price reforms. Munasinghe and Cruz were asked whether the effects of such reforms were overstated since much of the environmental damage in countries with structural adjustment programs resulted from their social impacts and effects on social structures. At least one participant argued that ignoring the social impacts of adjustment and the role of social structures in environmental damage was shortsighted on the part of the Fund and the Bank.

A participant wanted to know how feasible it was to design and implement environmental taxes in the context of developing countries. Another participant wanted to know if the World Bank had done studies on how the levels and patterns of environmental expenditures of the governments have been affected in countries undergoing severe fiscal stringency.

In response, Munasinghe argued that ensuring that desirable environmental policies will all be in place before macroeconomic reforms are implemented may not always be possible. When macroeconomic reforms cannot wait, it would seem necessary to have complementary policies, at least as add-ons, instead of completely ignoring them. As to the relevance of social structures to the environment, both Munasinghe and Cruz agreed that they were important, although they stressed that little analytical work had been done until now in the Bank as well as elsewhere that would facilitate its integration into the operational work of the Bank and the Fund.

Munasinghe gave many reasons why it is difficult to design adequate environmental taxes. It is not easy to decide who should be made to bear the tax or even determine its level. (Should it be based on the extent of damage, the level of emissions, or the size of the particulate matter that is causing the damage in the first place?) Regarding the impact of structural adjustment programs and fiscal stringency on environmental expenditures, the participants were informed that some work has been done at the World Bank. Another participant pointed out that a recent study of eight countries with structural adjustment programs in recent years showed no decline (as a proportion of GDP) in social expenditures (health and education).

Cielito Habito, responding to a question, thought that, at least in the Philippines, the authorities are now convinced of the urgent need for environmental policies to address the short-term negative impacts of macroeconomic adjustment on the environment.

One Fund staff member reminded the participants that, as a prior step, a synthesis of macroeconomic and environment objectives must take place in the member countries themselves, if the Fund staff is to design macroeconomic reform packages that would be fully supportive of the country’s environmental objectives. Most participants seemed to agree to the urgent need for a coordination of economic and environmental work at the country level itself.

The Fund and the Environment

The last session of the seminar focused on the Fund and the environment.

Stanley Fischer, in his luncheon remarks on what is reasonable to expect of the Fund in the environment area, stated that the work of the Fund and its staff is guided by the Articles of Agreement, which discourage member countries from resorting to macroeconomic policies “destructive of national and international prosperity” and in fact encourage them to adopt macroeconomic policies which would achieve monetary and financial stability and “contribute thereby … to the development of productive resources.” He argued that although the environment is not referred to in the Articles of Agreement, excessive exploitation of natural resources and increased deforestation, which can occur particularly when appropriate environmental policies are lacking, cannot be ignored because they can give rise to structural balance of payments problems and can reduce economic growth prospects.

He indicated that the Fund’s advice on public policy reforms is generally supportive of the environment; besides, the Fund, working closely with the World Bank, helps countries prepare Policy Framework Papers, which often include plans for addressing environmental problems. The Fund has been also supporting the work on environmental or “green” accounting being carried out by the United Nations, the World Bank, and others.

Finally, environmental issues tend to show up in Fund dealings with member countries in a number of ways. Developing countries, for example, whose economic growth strategy relies heavily on depletable resources are advised to use such resources at an optimal rate. Countries whose economies are still in transition are advised to remove price distortions and subsidies (e.g., for energy) and to eliminate soft budget constraints for state-owned enterprises. Industrial countries, which may already be paying attention to environmental issues, could consider the results of analytical research on the impact of environmental policies and conditions on the macroeconomy and incorporate them in policy formulation.

David Pearce, who initiated the panel discussion on the subject, was of the view that the Fund staff must take the environment into account because it makes little sense to revitalize the economy or bring about macroeconomic stability if it is at the expense of the resource base of the economy on which economic growth ultimately depends. Macro-economic stability without care for the environment will not be sustainable, and, in his opinion, the Articles of Agreement of the Fund do invite the staff to be concerned with sustainability. He argued that the fear that environment was a complex and multifaceted subject for which the Fund economists were not adequately trained was unfounded because the staff of the World Bank and the World Trade Organization have acquired the necessary environmental skills without much difficulty. The fact that the Fund staff already looks at the stock of mineral resource base in economies dependent on minerals, or the stock of oil in economies dependent on oil, or the stock of forests in economies dependent on timber, is already a good beginning. Such work should now be extended to other elements bearing on the environment, for example, soil base for productive agriculture, or the quality of air and water for human health and labor productivity. In his opinion, it will not be too difficult for Fund staff, who are well trained in economics, to acquire the relevant knowledge about the environment and to incorporate environmental concerns in their policy dialogues with the authorities of member countries.

Cielito Habito, the second panel discussant, reemphasized the need for the Fund to take environmental sustainability seriously for it is environmental sustainability that will ensure sustainability of economic growth in the longer run. In his opinion, integrating the environment into the design of macroeconomic programs should be relatively easy and can be done primarily through the design of the fiscal content of the program. On the public expenditure side, every attempt should be made to insulate environmental programs and projects from budgetary cutbacks, or at least prevent such programs and projects from becoming the first to suffer as a result of austerity measures. On the revenue side, the Fund staff could highlight environment-friendly tax measures, such as taxes on petroleum, pollution taxes, and forestry charges, in designing fiscal reform programs. Even in terms of other policy reforms, there was scope for structural adjustment programs to incorporate market-based incentive measures for encouraging the adoption of environmentally sound practices in the productive sectors of the economy, including appropriate pricing of natural resources and environmental charges. Habito was of the firm opinion that developing country policymakers are ready for policies that would support the objective of sustainable development and that environmental considerations are increasingly being woven into overall economic policymaking.

Andrew Steer, the third panel discussant, argued that, even with the knowledge that they currently have, Fund and Bank economists can do at least five things in support of the environment. First, they should be able to assess the first-order impacts of macroeconomic policy reforms on the environment in a more systematic manner. It should not be too difficult for them to prepare environmental impact statements covering, for example, the impact of devaluation and trade liberalization on the exportable extractive sector and on cropping patterns in the agricultural sector, the potential impact of budget cutbacks on public expenditures for environmental protection, and the potential impact of austerity on activity patterns among the poor. Second, having established these first-order impacts and identified the potential adverse effects, if any, they should be able to help countries design “first-best” environmental policies to mitigate such effects and, at the same time, integrate them into adjustment programs. It does not matter whether these policies are actually woven into the adjustment programs or are implemented in parallel; what does matter is that macroeconomic and environmental reforms get implemented simultaneously and effectively. Third, Fund and Bank economists should make every effort to incorporate environmental concerns into calculations of national income and other macroeconomic aggregates. Without this, one will never know if the nations are saving enough for the future. The present focus of Fund and Bank staff on man-made and produced assets only, to the complete neglect of natural assets and human assets, is shortsighted. Fourth, the Fund and Bank economists simply have to gain a better understanding of the impacts that structural reforms have on the environment, via their effects on informal traditional mechanisms, such as water and forest users associations, traditional communal management mechanisms, business-led self-enforcement schemes, voluntary conservation organizations. In Steer’s opinion, they, even more than governments, are the most effective mechanisms for the protection of the environment, especially in a developing country. Fifth, the staff of the two Bretton Woods institutions must build the support for macroeconomic stability and macroeconomic policy reforms within the environmental community, especially the mainstream analytical and professional NGOs. Steer thus saw ample scope for Fund and Bank staff to internalize environmental objectives into macroeconomic policy work even with the current state of knowledge.

Ved Gandhi, acting as the final panel discussant, highlighted what he considered to be the major conclusions of the seminar for the Fund staff. First, ignoring environmental degradation means ignoring its impact on human capital, natural capital, and output, all of which have a bearing on the sustainability of macroeconomic stability and economic growth. The Fund staff is therefore ill advised to ignore instances of serious environmental degradation or depletion of natural resources. Second, green national accounts are not absolutely essential for formulating appropriate short-term financial and macroeconomic policies. The Fund staff need not wait until environmentally adjusted national accounts become ready; until that occurs, they can take into account the most important environmental indicators, including the need for maintaining the basic social services, in designing macroeconomic and fiscal programs. Third, in some industrial countries where computable general equilibrium modeling is prevalent and the authorities have started using this tool in pursuing their economic objectives consistent with environmental targets, the Fund staff can bring this work to bear on their policy dialogues with the authorities. Fourth, the Fund staff can help countries exploit the very many win-win possibilities, giving greater attention to the removal of subsidies on environmentally damaging inputs, adjustment of utility and energy prices, levying or raising of stumpage fees, levying or increasing of environmental taxes, users’ fees, and other measures, and, at the same time, protecting crucial and essential environmental expenditures and investments from budgetary cuts. Fifth, the Fund staff can start examining the National Environmental Action Plans, wherever they exist, and start to bring the economic and environmental ministries together to identify the interest of the authorities in pursuing them. The staff can, then, help the authorities work out the financial and fiscal implications of such plans, if this has not already been done.

Vito Tanzi, in making his concluding remarks, pursued the question of the future involvement of the Fund staff with the environment. He admitted that knowledge about the extent of environmental degradation and the analytical tools readily available to deal with the subject are far from perfect and that prescriptions about environmental problems cannot be made with a great deal of confidence. Besides, one cannot foresee the role of technological change in presenting solutions that may be easier to adopt.

Nonetheless, Tanzi stressed that there are a few things that the Fund staff can do even without necessarily changing the mandate of the institution. They can make themselves aware of environmental concerns of the countries they work on. They can make these concerns enter into macroeconomic policy dialogues with the authorities of all countries, including countries not seeking financial support, to the extent that the authorities wish them to do so. Where the Fund is providing balance of payments support, they can encourage the country authorities to exploit various win-win opportunities highlighted again and again in the seminar. The Fund staff could also encourage developing countries with serious environmental problems and without institutional capabilities to seek assistance from the World Bank to develop appropriate complementary environmental policies for the short run as well as for the long run. Finally, Tanzi emphasized that the pace at which the Fund staff can act on the environment would depend upon the pace at which the countries themselves integrate their environmental concerns into their macroeconomic policymaking.

Part of the book series: Political Economy of Islam ((PEoI))

From a practical point of view, macroeconomic policies are usually classified into two broad categories: (i) structural policies that cover a wide range of measures designed to tackle obstacles to the fundamental drivers of growth, and to boost the economy’s competitiveness and growth potential in the medium and long run. The structural measures usually have medium and long-term effects; (ii) demand management policies—fiscal and monetary measures—that target short-term macroeconomic stability. Macroeconomic stability refers to a state of the economy that displays internal and external sustainable financial positions, which in turn increase positive prospects for saving, foreign capital inflows, investment, and sustained economic growth.

Durlauf ( 2018 ) reviewed widely the empirical evidence on institutions and growth, with methodologies ‎ranging from ‎historical studies to econometric analyses, with different studies making very different ‎theoretical ‎commitments as to what institutions means and how they affect economic development. Finally, ‎Durlauf ‎argues that “this breadth of evidentiary forms has given credibility to empirical institutional ‎economics, ‎allowing for the emergence of robust evidence of the importance of institutions and ‎robust ‎recommendations for policy”.‎

Góes ( 2015 ), using the Economic Freedom of the World Index as a proxy for institutions quality, found that on average, a 1% shock in institutional quality leads to a peak 1.7% increase in GDP per capita after six years. The index takes into account five institutions-related subcomponents: legal system reliability, monetary stability, burden of regulation, size of government, and freedom to trade internationally.

Public goods are defined as goods and services that are “non-rival” and “non-excludable.” In other words, no one can be excluded from the benefits and consumption by one person does not diminish consumption by another.

The High-Level Panel Report on the Post-2015 Development Agenda (2013) has made a strong plea for effective institutions, calling for a “fundamental shift” to recognize their significant role in contributing to citizens’ well-being.

Alesina and Giuliano ( 2015 ) noted that most of the empirical papers (if not all) follow the definition adopted by Guiso et al. ( 2005 ), where culture is defined as “those customary beliefs and values that ethnic, religious, and social groups transmit fairly unchanged from generation to generation.” Empirical papers, therefore, combine values and beliefs in the same definition. In contrast, conceptual papers had often treated values and beliefs ‎ differently. In empirical studies, the most common tool for measuring culture is through survey questions. The answers are then aggregated at the country level. (Example of data source: See World Values Survey Database).

See Wubbels et al. ( 2017 ).

Wubbels et al. ( 2017 ) argued “Education is crucial in helping people at all age levels to participate fully and responsibly in a democratic society, in its discourse and its institutions. Education… needs to include the competence to participate and deliberate.”

Social media is a tool for giving voice to those excluded from access to the mainstream media.

However, Information and communication technologies (ICTs) expansion raises also sharp concerns related to digital divide and a gap in broadband access between developed and developing countries, as well as within countries.

La Ferrara ( 2016 ), quoting (Singhal and Rogers 2004 ): “Educational entertainment (EE, or edutainment) is the process of purposely designing and implementing a media message to both entertain and educate, in order to increase audience members’ knowledge about an issue, create favorable attitudes, shift social norms, and change the overt behavior of individuals and communities”.

Commander and Nikoloski ( 2010 ), (Docquier 2014 ), Yildirim and Gökalp ( 2016 ).

See Bourguigon and Wangwe ( 2018 ) for a summary of the standard approaches (features and drawbacks) developed to identify the institutional factors hindering development or ways of remedying specific factors: historical case studies; contemporaneous cross-country analysis; and observable realities evaluated by Randomized Control Trials (RCT) techniques.

See Felipe and Usui ( 2008 ) for practical assessment of this methodology -features and limitations- and some proposal of directions for further improvements.

The EDI methodology uses a definition of “Institutions (are defined) as rules, procedures or other human devices that constrain individual behavior, either explicitly or implicitly, with a view to making individual expectations about others’ behavior converge and allowing individual actions to become coordinated.”

The programme has started with Tanzania, Benin, and Bangladesh as country study cases.

Most of the empirical studies use a broad definition of public capital, which includes public capital stock of roads (motorways and streets), water and sewer systems, schools, hospitals, conservation, and development structures.

The International Labour organization’s report ( 2018 ) worried about the fact that, the significant progress achieved in the past in reducing vulnerable employment has essentially stalled since 2012, with the rate remaining above 42%. In 2017, almost 1.4 billion workers are estimated to be in vulnerable forms of employment, and every year an additional 17 million join them. Moreover, many countries still have no minimum wage or collective bargaining and most minimum wages are significantly lower than what is needed to survive or what could be described as a living wage—a wage that is high enough to enable workers and their families to meet their needs for nutritious food and clean water, shelter, clothes, education, healthcare, energy, childcare and transport, as well as allowing for some savings and discretionary income (Oxfam International 2018 ).

Francese and Prady ( 2018 )‎ considered an Universal Basic Income as a benefit regularly (e.g., yearly or monthly) paid out in cash unconditionally to all residents in a country. Under such a program all residents would receive the same amount, with the benefit being benchmarked as a fraction of median equivalent income.

Oxfam international ( 2018 ) called for “reward work, not wealth.”

The benchmark model developed is a macroeconomic framework based on the combination of the Agent Based and Stock Flow Consistent approaches. The proposed framework provides a coherent and exhaustive representation of the inter-linkages between the real and financial sides of the economy viewed by the authors as a pivotal feature of every macroeconomic model.

Earlier survey on the issue (Lopez 2011 ) stressed a consensus among researchers that emphasized: (i) growth is fundamental for ‎poverty reduction; (ii) the brake on poverty alleviation is largely the result of high inequality; and ‎‎(iii) education, infrastructure, and economic stability promote both growth and shared income.

Aiyar and Ebeke ( 2019 ) underscored “that not accounting for inequality of opportunity will tend to bias empirical estimates of the relationship between income inequality and growth. This is likely to be an important factor behind the inconclusive state of this literature.”

According to Okeleke and Sardi, in 2018, mobile technologies and services generated 8.6% of GDP in Sub-Saharan Africa—a contribution that amounted to $144.1 billion of economic value added.

Beck ( 2013 ) argued that research methodology on financial deepening and policies in developing countries should mix theory and lessons from historic and present-day experiences in emergent and developed markets.

See Bhattarai ( 2015 ).

Financial conditions can be defined as the current state of financial variables that influence economic behavior and the future state of the economy. In theory, such financial variables may include anything that characterizes the supply or demand of financial instruments relevant for economic activity, a wide array of asset prices and quantities (both stocks and flows), as well as indicators of potential asset supply and demand (Hatzius 2010 ).

According to Khan ( 2003 ), adoption on inflation-targeting provides a solution to solve this puzzle.

Price risk could be defined as the risk of a decline in the value of a security or a portfolio.

Financial stability reflects a resilient financial system that is less likely to amplify adverse shocks.

See Adrian et al. ( 2016 ) for an extensive literature on monetary policy transmission and financial stability, macroprudential policies, interaction between macroprudential and monetary policies.

Macroprudential tools intervene directly in the business activities of financial market players. The toolkit includes: (i) quantitative restrictions on borrowers, instruments or activities; (ii) capital and provisioning requirements; (iii) other quantitative restrictions on financial institutions’ balance sheets; (iv) taxation/levies on activities or balance sheet composition; and (v) other, more institutional-oriented measures, such as accounting changes, changes to compensation, etc. Except for (i), which aims to affect demand for financing, all can be seen as affecting the supply side of financing (Claessens 2014 ).

From a modeling perspective, McKibbin and Stoeckel ( 2018 ) underscored that important aspects of the world economy that tend to be missing in most macroeconomic models are the importance of global linkages in trade and financial markets, the role of relative prices (sectoral disaggregation), and changes in risk premium that have been important sources of shocks for most countries since 2000 (as an illustration, see McKibbin and Stoeckel 2017 ).

Importance of Microeconomics – 6 Major Importance of Microeconomics | Explained in Detail

Importance of microeconomics.

Microeconomics is the branch of economics that deals with the study of how individual households and firms make decisions and how they interact in markets.

Microeconomics studies principles, problems, and policies concerning the optimum allocation of resources with maximum satisfaction.

The study of microeconomics takes place at the level of individual markets, industries, or sectors rather than at the level of the national economy as a whole.

Microeconomics attempts to analyze how markets allocate limited resources across alternative uses and establish relative prices for goods and services.

According to microeconomic theory, free markets produce a desirable allocation of resources. It also examines market failure, or when markets fail to produce efficient results.

Understanding such motives help manager to apply most appropriate technique to motivate every employee. Microeconomics plays a very important role in the study of economic theory.

The subject of microeconomics holds an important place in economics, both theoretically and practically. Economics plays an important role in formulating economic policies that will benefit the masses. Microeconomics dominated economics until very recently, especially before the Keynesian Revolution.

Even though macroeconomics is more popular these days, microeconomics is still important both theoretically and practically.

The study of microeconomics tells us how a free market economy, with its millions of consumers and producers, allocates its productive resources among the thousands of goods and services it produces.

The major importance of microeconomics are as follows:

a) Helpful in Business Decision Making

Microeconomics plays an important role in the business decision-making process. It guides business managers in optimal resource utilization, demand analysis, cost analysis, optimal production decisions, and pricing policy. Microeconomics plays an important role in business decision-making.

It helps the business managers in making production plans and trade decisions. It provides an analytical tool to examine the market mechanisms and helps business firms to take decision about their production and pricing policies. Read More

b) Helpful to understand the Working of the Economy

Microeconomics is helpful to understand the working of the economy as it explains the functioning of a free enterprise economy.

It tells us how millions of consumers and producers in an economy make decisions about the allocation of productive resources among millions of goods and services. The study of microeconomics contributes greatly to understanding how the economy works.

To understand how an economy works, we must collect enough information about the micro variables that are used in it, such as wage determination, product pricing, individual taxes, international trade, etc. Microeconomics can help us understand how consumers and sellers behave in an economy.

It enables us to understand the economic reasoning behind decisions like what to produce, for whom, and how much to produce, etc.

Microeconomics is crucial in understanding and influencing various economic indicators and policy decisions, highlighting its significance in shaping the broader economy.

Certainly, here’s an example of a table that illustrates the importance of microeconomics using various statistical measures:

c) Helpful in Formulating Economic Policies

Microeconomic tools are useful in designing price policy, taxation policy, and others in an economy dominated by the public sector. It is also useful in designing the prices of public utilities in an economy.Economic policies are formulated based on macroeconomic theories and tools.

Microeconomics is useful in two ways when formulating and analyzing policies. To begin with, demand-supply models can be used to analyze the effects of government policies on allocation of resources and pricing of products.

Additionally, microeconomics encompasses different economic theories and models that can be used in evaluating the impact of different theories both before they are developed and after they have been implemented.

The government must determine the effect of imposing a new tax on a certain product on demand, revenue, production, consumption, and burden on consumers, for example, if it decides to impose a new tax on a particular product. To formulate policies, macroeconomic theories are helpful.

d) Helpful in formulating Sectoral Policies

There are different sectors such as industry, tourism, trade, and others. An understanding of each of these sectors is imperative before an appropriate policy is designed for them. Microeconomics provides a useful tool for the government while making sectoral decisions.

The study of microeconomics helps in understanding economic welfare. A major part of microeconomics is price theory- the foundation of welfare economics.

To measure the degree of economic welfare of society, microeconomics helps to obtain information related to the number of products that society consumes.

In imperfect competition, resources are misallocated and the output obtained is never optimal. As a result of imperfect market conditions, production, consumption, and social welfare are reduced.

As a result, the imperfect market wastes a lot of resources, and economics tells us how to correct the inefficient allocation of resources.

e) Helpful in an efficient Allocation of Resources

Microeconomics efficiently allocates the resources. The microeconomic theory explains the condition of efficiency in both consumption and production that ensures maximum social welfare.

Resources for economic production are scarce. Optimal utilization of scarce resources can be achieved through the use of microeconomic theories. In microeconomics, the efficient conditions in the consumption and production areas are studied.

In microeconomics, the law of substitution provides that a consumer will maximize his satisfaction in any condition in which the ratio of marginal utilities equals the ratio of price of comparable commodities.

In similar fashion, a producer will maximize his profit when the ratio of the marginal product of the factor of production is equal to the ratio of their prices.

Consumers and producers are guided by these conditions for the efficient allocation of scarce resources. Hence, microeconomic theory recommends appropriate policies for achieving economic growth, prosperity, and stability in the economy.

f) Helpful in the Study of Human Behavior

Microeconomics studies many diminishing forms of human behavior with the help of the law of diminishing marginal utility, equi-marginal utility, indifference curve and revealed preference theory.

As opposed to interpreting economic models, behavioral economics analyzes why and how people sometimes make irrational decisions, and why and how their behavior differs from predictions.

Most people must make decisions at some point in their lives that affect their lives in some way, whether it is how much to pay for coffee, whether to enroll in graduate school, whether to maintain a healthy lifestyle, or what amount to contribute to retirement.

An individual may choose choice A over choice B because of reasons related to behavioral economics. People make decisions that are not in their own best interest because they are emotional and easily distracted.

What is microeconomics, and how does it differ from macroeconomics?

Microeconomics is a branch of economics that focuses on the study of individual economic units, such as households, firms, and markets.

It examines how these units make decisions regarding resource allocation, production, consumption, and pricing. Microeconomics is concerned with understanding the behavior of individual actors within the economy.

On the other hand, macroeconomics deals with the overall performance and behavior of the entire economy. It looks at aggregate measures like Gross Domestic Product (GDP), inflation, unemployment, and national income.

While microeconomics focuses on the “trees” or individual units, macroeconomics looks at the “forest” or the economy as a whole.

Why is microeconomics important for individuals and households in their daily lives?

Microeconomics is relevant to individuals and households in several ways:

Budgeting: It helps individuals make informed decisions about budgeting, spending, and saving by understanding how their choices impact their personal finances.

Consumer Behavior: Microeconomics explains why people make certain purchasing decisions, helping individuals make choices that maximize their satisfaction or utility within their budget constraints.

Labor Market: Understanding microeconomic concepts like wages, labor supply, and demand can aid individuals in negotiating better salaries and making career choices.

Investments: Microeconomic principles can inform investment decisions, such as choosing between different asset classes or evaluating the risk-return trade-offs.

How does microeconomics help businesses make better decisions?

Microeconomics provides businesses with tools and insights for decision-making in various areas:

Market Analysis: Businesses can analyze market structures to identify opportunities and threats, such as assessing entry barriers or competitive advantages.

Profit Maximization: Firms use microeconomics to make decisions aimed at maximizing profit, such as setting output levels and determining price points.

What role does microeconomics play in understanding consumer behavior and preferences?

Microeconomics plays a crucial role in understanding consumer behavior:

Utility Theory: Microeconomics uses utility theory to explain how consumers make choices to maximize their satisfaction or utility from consuming goods and services.

Budget Constraints: It examines how consumers allocate their limited budgets to purchase goods and services, considering factors like prices and income.

Demand Analysis: Microeconomics helps analyze how changes in prices and incomes affect consumer demand, leading to insights about price elasticity and income elasticity.

Consumer Surplus: It quantifies the benefit consumers receive when they are able to purchase goods at a price lower than their willingness to pay.

How does microeconomics impact pricing strategies in various industries?

Microeconomics influences pricing strategies by considering factors such as:

Market Structure: Different market structures (e.g., perfect competition, monopolistic competition, oligopoly, monopoly) have varying degrees of pricing power, and firms adjust strategies accordingly.

Elasticity of Demand: Microeconomics helps businesses determine price elasticity to set prices that maximize revenue. Inelastic demand allows for higher prices, while elastic demand may require lower prices to boost sales.

Cost Analysis: Firms consider production and distribution costs when setting prices to ensure profitability.

Competitive Analysis: Microeconomics guides firms in assessing their competitors’ pricing strategies and positioning their products effectively in the market.

What is the significance of microeconomics in resource allocation and efficiency?

Microeconomics is crucial for efficient resource allocation:

Resource Scarcity: It addresses the problem of allocating limited resources among competing uses, ensuring that resources are allocated efficiently to maximize overall welfare.

Opportunity Cost: Microeconomics emphasizes the concept of opportunity cost, which helps individuals and firms make choices that maximize their utility or profit while considering trade-offs.

Production Efficiency: Firms use microeconomic principles to achieve production efficiency by minimizing costs and using resources optimally.

Market Efficiency: Microeconomics explores the conditions under which markets are efficient, leading to the allocation of resources that maximizes societal welfare.

How does microeconomics contribute to the analysis of market structures, such as perfect competition and monopolies?

Microeconomics provides insights into different market structures:

Perfect Competition: It characterizes markets with many small firms, homogeneous products, and no pricing power. Microeconomics shows that in perfect competition, prices are determined by supply and demand, and firms are price takers.

Monopoly: In contrast, microeconomics examines monopolies, where a single firm dominates the market and has substantial pricing power. It explores how monopolies can maximize profit and the potential for regulatory intervention.

Oligopoly: Microeconomics analyzes oligopolistic markets, where a few large firms dominate. It considers strategic interactions, price leadership, and collusion among these firms.

Monopolistic Competition: This market structure features many firms selling differentiated products. Microeconomics helps firms in monopolistic competition set prices and differentiate their products effectively.

Why is microeconomics important for policymakers when crafting economic policies?

Policymakers use microeconomics to design policies that address specific economic issues:

Market Regulation: Microeconomics informs decisions about market regulation, antitrust laws, and consumer protection policies to promote competition and consumer welfare.

Taxation: It helps in designing tax policies that consider how taxes affect consumer behavior, business decisions, and income distribution.

Environmental Policies: Microeconomics aids in designing environmental regulations, such as cap-and-trade systems, to address externalities and promote sustainable practices.

What are the implications of microeconomics for income distribution and poverty alleviation?

Microeconomics informs policies related to income distribution and poverty alleviation:

Progressive Taxation: It supports progressive tax systems that impose higher tax rates on higher incomes to reduce income inequality.

Minimum Wage: Microeconomics is used to assess the effects of minimum wage policies on low-wage workers and their income levels.

Social Safety Nets: Policymakers use microeconomics to design social safety net programs like unemployment benefits and food assistance to reduce poverty.

How does microeconomics influence decision-making in the labor market, including wages and employment?

Microeconomics is highly relevant in the labor market:

Wage Determination: It explains how wages are determined based on the supply and demand for labor, as well as factors like skill levels, education, and labor market conditions.

Labor Supply: Microeconomics helps individuals make decisions regarding labor force participation, working hours, and career choices based on their utility-maximizing preferences.

Unemployment: It offers insights into the causes of unemployment and informs policies aimed at reducing it, such as job training programs and employment subsidies.

What is the relationship between microeconomics and environmental sustainability?

Microeconomics plays a role in promoting environmental sustainability:

Externalities: It addresses the issue of externalities, where the actions of individuals or firms have unintended impacts on the environment. Microeconomics helps design policies like carbon taxes or emissions permits to internalize these external costs.

Resource Allocation: Microeconomics considers how the allocation of resources affects environmental sustainability. It guides decisions on resource use, conservation, and renewable energy adoption.

Green Technologies: It encourages the development and adoption of green technologies by analyzing the costs and benefits associated with sustainability initiatives.

How does microeconomics help in understanding the concept of elasticity of demand and supply?

Microeconomics introduces the concept of elasticity, which measures how responsive the quantity demanded or supplied of a good is to changes in price or other factors:

Price Elasticity of Demand: It quantifies the percentage change in quantity demanded in response to a percentage change in price. Understanding demand elasticity helps businesses set optimal prices and assess the impact of price changes on revenue.

Income Elasticity of Demand: This measures how changes in income affect the quantity demanded. It helps firms tailor their marketing and product strategies to different income groups.

Cross-Price Elasticity of Demand: It shows how changes in the price of one good affect the demand for another. Firms use this information to make decisions about pricing and product substitutions.

Price Elasticity of Supply: This measures the responsiveness of quantity supplied to changes in price. It informs producers about how changes in market conditions affect their willingness to supply goods.

Why is microeconomics essential for entrepreneurs and startups?

Entrepreneurs and startups benefit from microeconomic principles:

Market Analysis: Microeconomics helps identify market opportunities, assess competition, and determine the potential demand for products or services.

Cost Management: It aids in cost analysis, budgeting, and resource allocation, ensuring efficient use of limited resources.

Pricing Strategies: Microeconomics guides startups in setting competitive prices and adapting to market changes.

Profit Maximization: Entrepreneurs use microeconomic insights to make decisions aimed at maximizing profit and sustaining growth.

How does microeconomics inform international trade decisions and policies?

Microeconomics plays a vital role in international trade:

Comparative Advantage: Microeconomics introduces the concept of comparative advantage, which helps countries determine what goods to specialize in and trade for maximum benefit.

Trade Barriers: It helps analyze the impact of trade barriers like tariffs and quotas on prices, trade volumes, and consumer welfare.

Exchange Rates: Microeconomics informs decisions about exchange rate policies and their effects on exports and imports.

What role does microeconomics play in analyzing the effects of government regulations on businesses and consumers?

Microeconomics is used to assess the impact of government regulations:

Regulatory Costs: It examines how regulations affect production costs, market entry, and competition.

Consumer Protection: Microeconomics helps evaluate the benefits of regulations aimed at protecting consumers from unsafe products or deceptive practices.

Antitrust and Competition Policy: It guides policymakers in preventing monopolistic behavior and promoting competition in markets.

How does microeconomics contribute to the study of market failures and the need for government intervention?

Microeconomics identifies instances of market failure, where markets do not allocate resources efficiently. These failures can include:

Externalities: Microeconomics shows how external costs or benefits not considered by buyers and sellers can lead to inefficient outcomes, necessitating government intervention.

Public Goods: It explains why public goods, like national defense, are underprovided by the market and require government provision.

Information Asymmetry: Microeconomics analyzes how information disparities between buyers and sellers can lead to adverse selection and moral hazard, requiring regulatory solutions.

What are the key concepts in microeconomics, such as opportunity cost and utility, and why are they important?

Opportunity Cost: Opportunity cost is the value of the next best alternative that must be foregone when a choice is made. It’s important because it highlights the concept of trade-offs in decision-making, which is fundamental in economics.

Utility: Utility refers to the satisfaction or happiness a consumer derives from consuming goods and services. It’s crucial because it helps explain why consumers make certain choices to maximize their well-being within their budget constraints.

Marginal Analysis: This involves assessing the incremental benefits and costs of small changes in decisions, such as producing one more unit or consuming one more unit of a good. It helps in optimizing choices.

Supply and Demand: These are fundamental concepts that explain how prices are determined in markets and how the quantity of goods and services exchanged is determined.

How does microeconomics provide insights into decision-making in the healthcare industry, including pricing of medical services and pharmaceuticals?

Pricing: Microeconomics is used to analyze pricing strategies in healthcare, considering factors like demand elasticity, cost structures, and insurance mechanisms. It helps determine fair pricing for medical services and pharmaceuticals.

Resource Allocation: It guides decisions about the allocation of healthcare resources, such as hospital beds, medical personnel, and equipment, to maximize patient welfare.

Importance: Childhood is a crucial developmental phase for mental health and cognitive function, both of which are commonly affected in patients with psychiatric disorders. This neurodevelopmental trajectory is shaped by a complex interplay of genetic and environmental factors. While common genetic variants account for a large proportion of inherited genetic risk, rare genetic variations, particularly copy number variants (CNVs), play a significant role in the genetic architecture of neurodevelopmental disorders. Despite their importance, the relevance of CNVs to child psychopathology and cognitive function in the general population remains underexplored. Objective: Investigating CNV associations with dimensions of child psychopathology and cognitive functions. Design, Setting, and Participants: ABCD study focuses on a cohort of over 11,875 youth aged 9 to 10, recruited from 21 sites in the US, aiming to investigate the role of various factors, including brain, environment, and genetic factors, in the etiology of mental and physical health from middle childhood through early adulthood. Data analysis occurred from April 2023 to April 2024. Main Outcomes and Measures: In this study, we utilized PennCNV and QuantiSNP algorithms to identify duplications and deletions larger than 50Kb across a cohort of 11,088 individuals from the Adolescent Brain Cognitive Development study. CNVs meeting quality control standards were subjected to a genome-wide association scan to identify regions associated with quantitative measures of broad psychiatric symptom domains and cognitive outcomes. Additionally, a CNV risk score, reflecting the aggregated burden of genetic intolerance to inactivation and dosage sensitivity, was calculated to assess its impact on variability in overall and dimensional child psychiatric and cognitive phenotypes. Results: In a final sample of 8,564 individuals (mean age=9.9 years, 4,532 males) passing quality control, we identified 4,111 individuals carrying 5,760 autosomal CNVs. Our results revealed significant associations between specific CNVs and our phenotypes of interest, psychopathology and cognitive function. For instance, a duplication at 10q26.3 was associated with overall psychopathology, and somatic complaints in particular. Additionally, deletions at 1q12.1, along with duplications at 14q11.2 and 10q26.3, were linked to overall cognitive function, with particular contributions from fluid intelligence (14q11.2), working memory (10q26.3), and reading ability (14q11.2). Moreover, individuals carrying CNVs previously associated with neurodevelopmental disorders exhibited greater impairment in social functioning and cognitive performance across multiple domains, in particular working memory. Notably, a higher deletion CNV risk score was significantly correlated with increased overall psychopathology (especially in dimensions of social functioning, thought disorder, and attention) as well as cognitive impairment across various domains. Conclusions and Relevance: In summary, our findings shed light on the contributions of CNVs to interindividual variability in complex traits related to neurocognitive development and child psychopathology.
