Macroeconomics

Macroeconomics is the study of the behavior of the economy as a whole. It concerns the business cycles that lead to unemployment and inflation, as well as the longer-term trends in output and living standards.

Macroeconomic Goals

OutputHigh level and sustainable growth

EmploymentHigh level of employment and low

involuntary unemployment

Stable PricesInternational tradeExport and import equilibrium and

exchange rate stability

Output

The ultimate objective of economic activity is to provide the goods and services that the population desires.

The most comprehensive measure of the total output in an economy is the gross national product (GNP).

GNP

Nominal GNP is measured in actual market prices.

Real GNP is calculated in constant or invariant prices.

Potential GNP is the long-run trend in real GNP. It represents the long-run productive capacity of the economy or the maximum amount the economy can produce while maintaining stable prices.

Employment

The unemployment rate measures the fraction of the labour force that is looking for but cannot find the work.

The labour force includes all employed persons and those unemployed individuals who are seeking jobs.

The unemployment rate tends to move with the business cycle.

Stable Prices

The third macroeconomic goal is to maintain stable prices within free markets.

A market economy uses prices as a yardstick to measure economic values.

Rapid price changes lead to economic inefficiency.

The most common measure of the overall price level is the consumer price index (CPI). The CPI measures the cost of a fixed basket of goods bought by the typical urban consumer.

The rate of inflation measures changes in the level of prices. It denotes the rate of growth or decline of the price level from one year to the next.

Inflation or Deflation

An inflation occurs when the level of price is growing (the rate of inflation is positive).

A deflation denotes that the level of price declines (the rate of inflation is negative).

A disinflation is a decrease in the rate of inflation. The slowing of the rate of inflation per unit of time.

International trade

International trade is becoming increasingly important to most country’s economy. International trade is beneficial to society even if some individuals are harmed by it. International trade includes import and export of goods, services, capital, borrowing and lending money etc.

Net export is the numerical difference between the value of a country’s exports and the value of its imports.

When net exports are positive, a trade surplus exists.

A trade deficit occurs when the value of imports is greater than the value of exports.

Exchange Rate StabilityForeign exchange rate represents the price of own currency in terms of the currency of other nation.When a nation’s exchange rate rises, the prices of imported goods fall while exports become more expensive for foreigners the nation becomes less competitive in world markets and net exports decline.Changes in exchange rates can also affect output, employment, and inflation.

Macroeconomic Policy Instruments

A policy instrument is an economic variable under the control of government that can affect one or more of the macroeconomic goals

Fiscal Policy

Fiscal policy is the use of government expenditures and taxes to affect aggregate demand and aggregate supply.

Page 17: Macroeconomic Goals and Instruments. Macroeconomics Macroeconomics is the study of the behavior of the economy as a whole. It concerns the business cycles

Fiscal Policy

Government expenditure includes government spending on goods and services. It determines the relative size of the public and private sectors.Taxation affects the overall economy in two ways: Taxes tend to reduce the amount people

spend on goods and servicesTaxes affect market prices, thereby

influencing incentives and behaviour.

Monetary Policy

Monetary policy determines the money supply as well as interest rates, in order to achieve desired economic objectives. Changes in the money supply move interest rates up or down and affect spending in sectors such as investment, housing, and net exports.Monetary policy has an important effect on both actual GNP and potential GNP.

International Economic Policy

International Economic Policy consists of two sets of policies:Trade policies, which consist of tarrifs,

quotas, and other devices that restrict or encourage imports and exports.

Exchange-rate setting. Exchange rate represents the price of one currency in terms of the currencies of the other nations. There are different systems to regulate foreign exchange market.

Incomes Policy

Incomes policies are government attempts to moderate inflation by direct steps (legislated wage, price controls).Incomes policies are the most contraversial of all macroeconomic policies.

Macroeconomic Policies and Goals in Practice

Macroeconomic policy requires choice among competing macroeconomic objectives. Macroeconomic dilemmas: Trade off between unemployment and

inflation.Greater investment in knowledge and capital

lowers current consumption.
