Frictional unemployment is the portion of unemployment that is due to the normal working of the labor market; used to denote short-run job/skill matching problems.Frictional unemployment is the portion of unemployment that is due to the normal working of the labor market; used to denote short-run job/skill matching problems.

Cyclical unemployment is the increase in unemployment that occurs during recessions and depressions. Employment tends to fall when aggregate output falls and rise when aggregate output rises.Cyclical unemployment is the increase in unemployment that occurs during recessions and depressions. Employment tends to fall when aggregate output falls and rise when aggregate output rises.

Everyone who wants a job at W* will have one. There is always full employment in this sense.If labor demand decreases, the equilibrium wage will fall. Everyone who wants a job at W* will have one.

This means that the AS curve is vertical. Therefore, monetary and fiscal policy cannot affect the level of output and employment in the economy.This means that the AS curve is vertical.

The unemployment rate may sometimes seem high even though the labor market is working well.The unemployment rate may sometimes seem high even though the labor market is working well. The fact that people are willing to work at a wage higher than the current wage does not mean that the labor market is not working.The fact that people are willing to work at a wage higher than the current wage does not mean that the labor market is not working.

9 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair Explaining the Existence of Unemployment The term sticky wages refers to the downward rigidity of wages as an explanation for the existence of unemployment.The term sticky wages refers to the downward rigidity of wages as an explanation for the existence of unemployment. If wages “stick” at W 0 rather than fall to the new equilibrium wage of W* following a shift of demand, the result will be unemployment equal to L 0 – L 1.If wages “stick” at W 0 rather than fall to the new equilibrium wage of W* following a shift of demand, the result will be unemployment equal to L 0 – L 1.

10 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair Explaining the Existence of Unemployment One explanation for downwardly sticky wages is that firms enter into social, or implicit, contracts. These contracts are unspoken agreements between workers and firms that firms will not cut wages.One explanation for downwardly sticky wages is that firms enter into social, or implicit, contracts. These contracts are unspoken agreements between workers and firms that firms will not cut wages.

11 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair Explaining the Existence of Unemployment The relative-wage explanation of unemployment holds that workers are concerned about their wages relative to the wages of other workers in other firms and industries. They may be unwilling to accept wage cuts unless they know other workers are receiving similar cuts.The relative-wage explanation of unemployment holds that workers are concerned about their wages relative to the wages of other workers in other firms and industries.

12 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair Explaining the Existence of Unemployment Explicit contracts are employment contracts that stipulate workers’ wages, usually for a period of one to three years. Wages set in this way do not fluctuate with economic conditions.Explicit contracts are employment contracts that stipulate workers’ wages, usually for a period of one to three years. Wages set in this way do not fluctuate with economic conditions. Cost of living adjustments (COLAs) are contract provisions that tie wages to changes in the cost of living. The greater the inflation rate, the more wages are raised.Cost of living adjustments (COLAs) are contract provisions that tie wages to changes in the cost of living.

13 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair Explaining the Existence of Unemployment The efficiency wage theory is an explanation for unemployment that holds that the productivity of workers increases with the wage rate. If this is so, firms may have an incentive to pay wages above the market- clearing rate.The efficiency wage theory is an explanation for unemployment that holds that the productivity of workers increases with the wage rate.

21 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair The Role of Import Prices The AS curve shifts when input prices change, and input prices are affected by the price of imports. There were no large shifts in the AS curve in the 1960s due to changes in the price of imports.The AS curve shifts when input prices change, and input prices are affected by the price of imports.

22 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair The Role of Import Prices The price of imports changed very little in the 1960s and early 1970s. It increased substantially in 1974 and again in 1979–1980. Since 1981, the price of imports has changed very little.

Wage inflation is affected by expectations of future price inflation. Price expectations that affect wage contracts eventually affect prices themselves.Expectations are self-fulfilling.

Rising costs push the short-run AS curve to the left. The quantity supplied will end up back at Y 0.When output is pushed above potential GDP (Y 0 ), there is upward pressure on costs.

26 © 2002 Prentice Hall Business PublishingPrinciples of Economics, 6/eKarl Case, Ray Fair The NAIRU—The Nonaccelerating Inflation Rate of Unemployment Many economists believe the relationship between the change in the inflation rate and the unemployment rate is as depicted by the PP curve in this figure.Many economists believe the relationship between the change in the inflation rate and the unemployment rate is as depicted by the PP curve in this figure. Only when the unemployment rate is equal to the NAIRU is the price level changing at a constant rate (no change in the inflation rate).Only when the unemployment rate is equal to the NAIRU is the price level changing at a constant rate (no change in the inflation rate).

To the right of the NAIRU the price level is decelerating (negative changes in the inflation rate).To the right of the NAIRU the price level is decelerating (negative changes in the inflation rate).

A possible recent source of favorable shifts is increased foreign competition, which may have kept both wage costs and other input costs down.A possible recent source of favorable shifts is increased foreign competition, which may have kept both wage costs and other input costs down.
