5. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 5 of 47 The Labor Market: Basic Concepts The labor force (LF) is the number of employed plus unemployed: LF = E + U unemployment rate The number of people unemployed as a percentage of the labor force. Unemployment rate = U/LF

6. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 6 of 47 The Labor Market: Basic Concepts frictional unemployment The portion of unemployment that is due to the normal working of the labor market; used to denote short-run job/skill matching problems. structural unemployment The portion of unemployment that is due to changes in the structure of the economy that result in a significant loss of jobs in certain industries. cyclical unemployment The increase in unemployment that occurs during recessions and depressions.

7. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 7 of 47 The Classical View of the Labor Market labor demand curve A graph that illustrates the amount of labor that firms want to employ at each given wage rate. labor supply curve A graph that illustrates the amount of labor that households want to supply at each given wage rate.

8. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 8 of 47 The Classical View of the Labor Market Classical economists believe that the labor market always clears. If the demand for labor shifts from D 0 to D 1, the equilibrium wage will fall from W 0 to W 1. Anyone who wants a job at W 1 will have one.  FIGURE 14.1 The Classical Labor Market

9. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 9 of 47 The classical view of the unemployment market is consistent with the following idea: a.The wage rate adjusts to equate the quantity of labor demanded with the quantity of labor supplied; therefore, persistent unemployment above the frictional and structural amount is unlikely. b.If the wage rate in the labor market is too low, people will work for themselves. c.The amount of labor that a firm hires depends on the value of the output that workers produce. d. All of the above.

10. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc.

11. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 11 of 47 The Classical View of the Labor Market The Classical Labor Market and the Aggregate Supply Curve The classical idea that wages adjust to clear the labor market is consistent with the view that wages respond quickly to price changes. This means that the AS curve is vertical. When the AS curve is vertical, monetary and fiscal policy cannot affect the level of output and employment in the economy.

12. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 12 of 47 The Classical View of the Labor Market The Unemployment Rate and the Classical View The unemployment rate is not necessarily an accurate indicator of whether the labor market is working properly. The measured unemployment rate may sometimes seem high even though the labor market is working well.

13. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 13 of 47 Explaining the Existence of Unemployment Sticky Wages sticky wages The downward rigidity of wages as an explanation for the existence of unemployment. If wages “stick” at W 0 instead of falling to the new equilibrium wage of W* following a shift of demand from D 0 to D 1, the result will be unemployment equal to L 0 - L 1.  FIGURE 14.2 Sticky Wages

Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 14 of 47 Refer to the graph below. The meaning of “sticky wages” in this graph refers to: a.The decrease in the equilibrium wage that results after the decrease in demand. b.The failure of the wage rate to fall after the decrease in demand. c.The tendency for the wage rate to rise above W0 after the decrease in demand. d.The decrease in unemployment that results after the decrease in demand.

16. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 16 of 47 Explaining the Existence of Unemployment Sticky Wages social, or implicit, contracts Unspoken agreements between workers and firms that firms will not cut wages. Social, or Implicit, Contracts relative-wage explanation of unemployment An explanation for sticky wages (and therefore unemployment): If workers are concerned about their wages relative to other workers in other firms and industries, they may be unwilling to accept a wage cut unless they know that all other workers are receiving similar cuts.

17. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 17 of 47 Explaining the Existence of Unemployment Sticky Wages explicit contracts Employment contracts that stipulate workers’ wages, usually for a period of 1 to 3 years. Explicit Contracts cost-of-living adjustments (COLAs) Contract provisions that tie wages to changes in the cost of living. The greater the inflation rate, the more wages are raised.

19. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 19 of 47 Explaining the Existence of Unemployment Efficiency Wage Theory efficiency wage theory 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.

20. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 20 of 47 The efficiency wage is among the theories of unemployment that explain why: a.Firms tend to pay wages above the wage at which the quantity of labor demanded equals the quantity supplied. b.Firms tend to pay wages below the wage at which the quantity of labor demanded equals the quantity supplied. c.Firms prefer to pay the wage at which quantity supplied equals quantity demanded in the labor market. d.There is only one level of the wage rate at which quantity supplied equals quantity demanded, called the efficiency wage rate.

22. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 22 of 47 Explaining the Existence of Unemployment Imperfect Information Firms may not have enough information at their disposal to know what the market-clearing wage is. In this case, firms are said to have imperfect information. If firms have imperfect or incomplete information, they may set wages wrong—wages that do not clear the labor market.

23. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 23 of 47 Explaining the Existence of Unemployment Minimum Wage Laws minimum wage laws Laws that set a floor for wage rates—that is, a minimum hourly rate for any kind of labor. An Open Question The aggregate labor market is very complicated, and there are no simple answers to why there is unemployment.

40. CHAPTER 14 The Labor Market In the Macroeconomy © 2009 Pearson Education, Inc. Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 40 of 47 The Short-Run Relationship Between the Unemployment Rate and Inflation Expectations and the Phillips Curve Expectations are self-fulfilling. This means that wage inflation is affected by expectations of future price inflation. Price expectations that affect wage contracts eventually affect prices themselves. Inflationary expectations shift the Phillips Curve to the right.

There is a short-run trade-off between inflation and unemployment, but other factors besides unemployment affect inflation. Policy involves more than simply choosing a point along a nice smooth curve.

Publishing as Prentice Hall Principles of Macroeconomics 9e by Case, Fair and Oster 44 of 47 The Long-Run Aggregate Supply Curve, Potential Output, and the Natural Rate of Unemployment If the AS curve is vertical in the long run, so is the Phillips Curve. In the long run, the Phillips Curve corresponds to the natural rate of unemployment—that is, the unemployment rate that is consistent with the notion of a fixed long-run output at potential output. U* is the natural rate of unemployment.  FIGURE 14.10 The Long-Run Phillips Curve: The Natural Rate of Unemployment
