Chapter 11
THE BUSINESS CYCLE, UNEMPLOYMENT, AND INFLATION
Chapter in a Nutshell
1. The business cycle refers to recurrent ups and downs in the level of economic activity
extending over several years. Although business cycles vary in intensity and duration, we
divide each into four phases: peak, recession, trough, and recovery.
2. When real GDP decreases for at least two consecutive quarters, we say that the economy is in
a recession. A depression is a very deep and prolonged recession. Since no subsequent
recession has approached the severity of the Great Depression, the term depression is often
used as a reference to the slump of the 1930s.
3. Many economists believe that a change in total spending is the immediate determinant of
domestic output and employment. However, other economists maintain that changes in the
supply side of the market, such as the development of better technologies or decreases in
natural resources cause business cycles.
4. The unemployment rate is the number of people unemployed divided by the number of
persons in the labor force. Although economists take great care in calculating the
unemployment rate, it suffers from problems involving part-time employment and discouraged
workers.
5. Not everyone who is unemployed is unemployed for the same reason. In describing labor
markets, economists refer to frictional unemployment, cyclical unemployment, and structural
unemployment. To mitigate the costs of unemployment, government has many programs such
as education and training programs and also unemployment insurance.
6. Economists call the level of unemployment at which there is no cyclical unemployment the
“natural rate of unemployment.” The natural rate of unemployment is the sum of frictional
and structural unemployment and is the economists’ notion of “full employment.” Most
economists estimate the natural rate of unemployment to be between 4 and 6 percent of the
labor force.
7. Inflation is a sustained or continuous rise in the general price level while deflation is a
continuing fall in the average price level. The most frequently cited indicator of inflation is
the consumer price index.
8. Inflation results in a decrease in the purchasing power of a fixed amount of income, a
redistribution of wealth from creditors to debtors, declining real interest rates on savings, and
higher tax revenues for the government.
9. Inflation may be caused by forces taking place on the buyers’ side of the market or the sellers’
side of the market. Inflation originating from upward pressure on the buyers’ side of the
market is called demand-pull inflation. Cost-push inflation is caused by upward pressure on
the sellers’ side of the market.
