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

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.

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.

The Classical View of the Labor Market  FIGURE 29.1 The Classical Labor Market Classical economists believe that the labor market always clears. If the demand for labor shifts from D0 to D1, the equilibrium wage will fall from W0 to W1. Anyone who wants a job at W1 will have one.

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.

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.

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.

Explaining the Existence of Unemployment Sticky Wages sticky wages The downward rigidity of wages as an explanation for the existence of unemployment.  FIGURE 29.2 Sticky Wages If wages “stick” at W0 instead of falling to the new equilibrium wage of W* following a shift of demand from D0 to D1, the result will be unemployment equal to L0 - L1.

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.

Explaining the Existence of Unemployment Sticky Wages Social, or Implicit, Contracts social, or implicit, contracts Unspoken agreements between workers and firms that firms will not cut wages. 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.

Explaining the Existence of Unemployment Sticky Wages Explicit Contracts explicit contracts Employment contracts that stipulate workers’ wages, usually for a period of 1 to 3 years. 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.

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.

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.

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.

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.

Refer to the figure below. What happens in this labor market if the minimum wage (W0) is abolished? a. Unemployment will rise. b. Unemployment will fall. c. The quantity of labor demanded falls. d. The quantity of labor supplied rises.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation In the short run, the unemployment rate (U) and aggregate output (income) (Y) are negatively related.  FIGURE 29.3 The Aggregate Supply Curve The AS curve shows a positive relationship between the price level (P) and aggregate output (income) (Y).

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation  FIGURE 29.4 The Relationship Between the Price Level and the Unemployment Rate This curve shows a negative relationship between the price level (P) and the unemployment rate (U). As the unemployment rate declines in response to the economy’s moving closer and closer to capacity output, the price level rises more and more.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation inflation rate The percentage change in the price level. Phillips Curve A curve showing the relationship between the inflation rate and the unemployment rate.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation  FIGURE 29.5 The Phillips Curve The Phillips Curve shows the relationship between the inflation rate and the unemployment rate.

Which of the following relationships is correct? a. There is a positive relationship between unemployment and output. b. There is a negative relationship between output and the overall price level. c. There is a negative relationship between the unemployment rate and the price level. d. There is a negative relationship between output and employment.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation The Phillips Curve: A Historical Perspective  FIGURE 29.6 Unemployment and Inflation, 1960–1969 During the 1960s, there seemed to be an obvious trade-off between inflation and unemployment. Policy debates during the period revolved around this apparent trade-off.

Policy discussions in the 1960s concerning the Phillips Curve revolved around the issue of: a. What point to choose along a smooth Phillips Curve. b. What to do about a highly unstable Phillips Curve. c. How to maintain low inflation and at the same time lower the unemployment rate. d. How to maintain low unemployment and at the same time lower the inflation rate.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation The Phillips Curve: A Historical Perspective  FIGURE 29.7 Unemployment and Inflation, 1970–2007 From the 1970s on, it became clear that the relationship between unemployment and inflation was anything but simple.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation Aggregate Supply and Aggregate Demand Analysis and the Phillips Curve  FIGURE 29.8 Changes in the Price Level and Aggregate Output Depend on Shifts in Both Aggregate Demand and Aggregate Supply

If there is no systematic relationship between inflation and unemployment, it is because: a. The aggregate demand curve shifts, without a shift in the aggregate supply curve. b. Both the aggregate demand and the aggregate supply curve shift simultaneously. c. Neither the aggregate demand nor the aggregate supply curves shift. d. Government policies have effectively eradicated inflation and unemployment.

The Short-Run Relationship Betweenthe 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.

Refer to the graph below. The impact of higher inflationary expectations on this Phillips curve is reflected by the move: a. From a to b. b. From a to c. c. From a to d. d. None of the above. Inflationary expectations do not affect the Phillips curve.

The Short-Run Relationship Betweenthe Unemployment Rate and Inflation Is There a Short-Run Trade-Off between Inflation and Unemployment? 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.

The Long-Run Aggregate Supply Curve, Potential Output, and the Natural Rate of Unemployment  FIGURE 29.10 The Long-Run Phillips Curve: 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.

The Long-Run Aggregate Supply Curve, Potential Output, and the Natural Rate of Unemployment natural rate of unemployment The unemployment that occurs as a normal part of the functioning of the economy. Sometimes taken as the sum of frictional unemployment and structural unemployment.

The Long-Run Aggregate Supply Curve, Potential Output, and the Natural Rate of Unemployment The Nonaccelerating Inflation Rate of Unemployment (NAIRU) NAIRU The nonaccelerating inflation rate of unemployment.  FIGURE 29.11 The NAIRU Diagram To the left of the NAIRU, the price level is accelerating (positive changes in the inflation rate); to the right of the NAIRU, the price level is decelerating (negative changes 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).

Refer to the figure below. Which of the following causes a leftward shift in the PP curve? a. A positive change in the rate of inflation. b. A negative change in the rate of inflation. c. An adverse change in input prices. d. A favorable change in input prices.
