B) On Macro- and Microeconomics

Ukranian: Economists know that there is considerable controversy about macroeconomic models because some of them do not match the fluctuations in actual economies. Besides, a lack of clear connection between macroeconomics and microeconomics has long been a source of discontent among economists. What is macroeconomics all about from your point of view?

Foreigner: Essentially, macroeconomics dates from Keynes and I stick to the concepts of Keynesian policies, according to which macroeconomics is a branch of economics concerned with the analysis of the economy in the large.

U.: So, if I get you right, macroeconomists study such economic aggregates as total expenditure, income and production, employment, prices and wages, external trade flows, tax revenues and government spendings, the stock of money and so on.

F.: I'd say that they disaggregate the economy into homogeneous categories and then integrate the determinants of the behaviour of each of these aggregates to provide models of the whole of economy.

U.: Is there a regularity in the behaviour of these economic aggregates?

F.: Yes. Economies develop in cycles. The term "cycle" refers to fluctuations in national economic activity over a period of time. Indicators of the cycle are variations in rates of economic growth, industrial output, capacity utilization, employment and price changes.

U.: What does the length of the cycle depend on?

F.: Fluctuations in the intensity of economic activity can be generated by both internal and external influences. For example, economic production may collapse for a number of reasons: natural disasters, hyperinflation or loss of political control, etc.

U.: As a result of cyclical development an economy may lose equilibrium. What indicators characterize economic equilibrium?

F.: First of all, it is aggregate demand and supply, then I'd mention the general price level, the unemployment rate, general consumption and investment. These are the aggregates that determine the output and the economic growth. If demand exceeds supply the economy is "overheating", which causes inflation, and if demand falls and is behind supply it brings about recession and growing unemployment.

U.: Now we've come to the most important question. How can macroeconomic disequilibrium be eliminated?

F.: Economic laws cannot be changed. But governments can influence the economic development through their economic policies.

U.: This idea of the responsibility of the government has become widespread, but how can the government create the proper conditions for market forces?

F.: It is usually done with the help of macroeconomic research and analysis of factors determining volumes of production, employment, interest rates and prices, dynamics of tax collection, and government spendings, money supply, as well as instruments underlying the elaboration of the economic policy. Besides, economists study the country's economic interactions with the rest of the world by analysing foreign trade flows.

U.: As you've said, the major macroeconomic index is the output. How is it determined?

F.: It can be done with the help of national accounts systems which are sort of macroeconomic statistical schemes for the presentation of the needed information on macroeconomic variables in a systematic way. For example, the System of National Accounts (SNA) has been used by market economies quite successfully for a number of decades.

U.: Yes, we know that the accounts of this system help to answer such basic economic questions as "What and how much does an economy produce?", "Which are the producing sectors?" and "How is the national income divided among the factors of production, notably labour and capital?"

F.: Summing up, I'd say that various indicators which are part of the SNA, allow to measure the total output and factors affecting the economic performance at a given moment. In market economies output is typically defined either in terms of the Gross Domestic Product (GDP) or the Gross National Product (GNP).

U.: What are the practical implications of macroeconomics?

F.: At a practical level, macroeconomics attempts to accomplish three tasks: to explain the changes in economic aggregates, to predict the consequences of certain recent developments, and to guide policy-makers in their attempts to influence future events in pursuit of economic objectives.
