First, explain what the participation rate represents. Second, explain why the participation rate has increased. Answer: The participation rate is the ratio of the labor force to the working age population. One of the reasons for the significant increase in the participation rate is the increasing participation of women in the labor force.Diff: 217) What effect does the existence of discouraged workers have on the ability of the official unemployment rate to provide accurate information about the extent to which labor is employed? Answer: Discouraged workers are individuals who have stopped searching for employment because, for example, they have become "discouraged" with the prospects of finding employment. Once they stop searching (after 4 weeks), they are no longer counted as unemployed and, therefore, in the labor force. Such a dynamic would cause the official unemployment to fall. Alternatively, the existence of discouraged workers implies that the official unemployment rate underestimates the extent to which labor is being is not being used. This explains why the existence of discouraged workers can cause the unemployment rate to be an imperfect measure of the utilization of labor.Diff: 218) First, provide a brief explanation of what the unemployment rate measures. Second, explain how changes in each of the components of the unemployment rate can cause changes in the unemployment rate.Answer: The unemployment rate measures the percentage of the labor force that is unemployed. The unemployment rate is based on a monthly survey of households. Individuals are classified as employed, unemployed, or out of the labor force. Individuals employed or unemployed are in the labor force. Suppose individuals decide to enter the labor force for the first time. This increase in the size of the labor force, all else fixed, would cause an increase in the unemployment rate.On the other hand, if there were an increase in the number of individuals unemployed (caused by, for example, firms laying off workers as demand for their products falls), we would observe no change in the labor force but an increase in the unemployment rate.Diff: 27.2 Movements in Unemployment1) Data on labor-force flows show thatA) almost all separations are due to death.B) almost all separations are due to serious illness.C) almost all separations are quits.D) almost all separations are layoffs.E) none of the aboveAnswer: EDiff: 22) Data on labor-force flows show thatA) in any given month, almost none of the unemployed gets jobs.B) in any given month, almost all of the unemployed gets jobs.C) the average duration of unemployment is about 2 weeks.D) the average duration of unemployment is about 2 years.E) in any given month, about one-fourth of the unemployed get jobs.Answer: EDiff: 23) Which of the following variables is most directly determined in the labor market?A) stock pricesB) nominal wagesC) interest ratesD) all of the aboveE) none of the aboveAnswer: BDiff: 14) The two labor markets in the "dual labor market" areA) southern versus northern.B) western versus eastern.C) English speaking versus non-English speaking.D) domestic versus foreign.E) none of the aboveAnswer: EDiff: 15) When the Current Population Survey (CPS) was introduced in 1940, it was based on a survey of approximately 8,000 households. The CPS survey is now based on a survey of how many households?A) 8,000B) 10,000C) 12,000D) 20,000E) 60,000Answer: EDiff: 26) As the unemployment rate falls,A) the proportion of the unemployed finding a job increases.B) the separation rate increases.C) the young and unskilled experience larger-than-average decreases in unemployment.D) both A and C.E) all of the aboveAnswer: DDiff: 27.3 Wage Determination1) Which of the following statements about wage setting is true?A) most workers in the U.S. have their wages set by formal contracts.B) formal contracts play a more important role in Japan and Western Europe than in the United States.C) the minimum wage in the U.S. is about 75% of the average wage.D) all of the aboveAnswer: BDiff: 12) The reservation wage isA) the wage that an employer must pay workers to reduce turnover to a reasonable level.B) the wage that ensures a laid-off individual will wait for re-hire, rather than find another job.C) the lowest wage firms are allowed by law to pay workers.D) the wage offer that will end a labor-strike.E) none of the aboveAnswer: EDiff: 13) Efficiency wage theory suggests thatA) workers will be paid less than their reservation wage.B) productivity might drop if the wage rate is too low.C) the government can only set tax rates so high before people will prefer not to work.D) unskilled workers will have a lower turnover rate than skilled workers.E) firms will be more resistant to wage increases as the labor market tightens. Answer: BDiff: 24) If efficiency wage theory is valid, we would expect a relatively low premium over the reservation wage whenA) the unemployment rate is low.B) the job requires very little training.C) workers can be easily monitored.D) workers have few other options for employment in the area.E) all of the aboveAnswer: CDiff: 25) Henry Ford's experiment with efficiency wages resulted inA) a dramatic drop in productivity.B) a dramatic increase in the turnover rate.C) a reduction in the layoff rate.D) new problems with the work force, like drunkenness and reckless driving.E) no noticeable effects.Answer: CDiff: 26) In the wage-setting relation, the nominal wage tends to decrease whenA) the price level increases.B) the unemployment rate decreases.C) unemployment benefits decrease.D) the minimum wage increases.E) all of the aboveAnswer: CDiff: 17) In the wage setting relation W = P e F(u,z), the variable z does not include which of the following variables?A) the minimum wageB) unemployment benefitsC) the extent to which firms mark up prices over their marginal costD) all of the aboveE) none of the aboveAnswer: CDiff: 18) Labor productivity is represented by which of the following?A) the ratio of output to employmentB) workers per unit of capitalC) capital per workerD) the ratio of output to populationE) the ratio of output to the labor forceAnswer: ADiff: 19) Today, about ________ of U.S. workers have their wages set by collective bargaining agreements.A) 10%B) 15%C) 20%D) 25%Answer: ADiff: 210) Explain several implications and characteristics of efficiency wage theories.Answer: The efficiency wage theory suggests that firms will pay workers a wage in excess of the workers' reservation wage to minimize quits and to increase productivity. The efficiency wage theory also suggests that nominal wages will be a function of labor market conditions. As the unemployment rate falls, the nominal wage will rise.Diff: 211) Explain how an increase in the unemployment rate will affect bargaining power and nominal wages.Answer: As the unemployment rate increases, it is more difficult for individuals to find employment at other firms. So, workers' bargaining power will fall. As bargaining power falls, the nominal wage will fall.Diff: 212) First, explain what the WS relation represents. Second, explain why it has its particular shape.Answer: The WS relation illustrates the effect of changes in the unemployment rate on the real wage implied by the wage-setting behavior of firms and workers. The WS curve (or relation) is downward sloping because as the unemployment rate increases, workers have less bargaining power so the nominal wage will decrease. This decrease in W, given P, implies that the real wage will also fall. Hence, the WS curve is downward sloping.Diff: 27.4 Price Determination1) The price setting equation is represented by the following: P = (1 + m)W. When there is perfect competition, we know that m will equalA) W.B) P.C) 1.D) W/P.E) none of the aboveAnswer: CDiff: 22) Explain why nominal wages are a function of the expected price level.Answer: Workers and firms care about the real wage. Nominal wages are typically set for a period of time by contracts. Individuals will, therefore, be concerned about what the future price level will be when determining the nominal wage. When setting the nominal wage, individuals will form expectations of what the future price level will be. They will use this to help determine the nominal wage.Diff: 27.5 The Natural Rate of Unemployment1) The natural rate of unemployment is the rate of unemploymentA) that occurs when the money market is in equilibrium.B) that occurs when the markup of prices over costs is zero.C) where the markup of prices over costs is equal to its historical value.D) that occurs when both the goods and financial markets are in equilibrium.E) none of the aboveAnswer: EDiff: 22) The natural level of output is the level of output that occurs whenA) the goods market and financial markets are in equilibrium.B) the economy is operating at the unemployment rate consistent with both the wage-setting and price-setting equations.C) the markup (m) is zero.D) the unemployment rate is zero.E) there are no discouraged workers in the economy.Answer: BDiff: 23) Suppose we wish to examine the determinants of the equilibrium real wage and equilibrium level of employment (N). In a graph with the real wage on the vertical axis, and the level of employment on the horizontal axis, the price-setting relation will now beA) a vertical line.B) a horizontal line.C) an upward sloping line.D) a downward sloping line.E) kinked at the natural rate of unemployment.Answer: BDiff: 24) Suppose we wish to examine the determinants of the equilibrium real wage and equilibrium level of employment (N). In a graph with the real wage on the vertical axis, and the level of employment on the horizontal axis, the wage-setting relation will now beA) a vertical line.B) a horizontal line.C) an upward sloping line.D) a downward sloping line.E) a curve that first slopes upward, then downward.Answer: CDiff: 25) The natural level of employment (N) will increase when which of the following occurs?A) an increase in the markup of prices over costsB) a reduction in unemployment benefitsC) an increase in the actual unemployment rateD) all of the aboveE) none of the aboveAnswer: BDiff: 26) Suppose workers and firms expect the overall price level to increase by 5%. Given this information, we would expect thatA) the nominal wage will increase by less than 5%.B) the nominal wage will increase by exactly 5%.C) the nominal wage will increase by more than 5%.D) the real wage will increase by 5%.E) the real wage will increase by less than 5%.Answer: BDiff: 27) Suppose the actual unemployment rate decreases. This will causeA) an upward shift in the WS curve.B) a downward shift in the WS curve.C) an upward shift in the PS curve.D) a downward shift in the PS curve.E) none of the aboveAnswer: EDiff: 28) Suppose the actual unemployment rate increases. This will causeA) an upward shift in the WS curve.B) a downward shift in the WS curve.C) an upward shift in the PS curve.D) a movement along the WS and the PS curves.E) none of the aboveAnswer: DDiff: 29) With the real wage on the vertical axis and the unemployment rate on the horizontal axis, we know thatA) the WS curve is upward sloping.B) the WS curve is downward sloping.C) the PS curve is upward sloping.D) the PS curve is downward sloping.Answer: BDiff: 210) Based on wage setting behavior, we know that a reduction in the unemployment rate will causeA) no change in the real wage.B) a reduction in the real wage.C) an increase in the real wage.D) an upward shift of the WS curve.Answer: CDiff: 211) Based on price setting behavior, we know that a reduction in the unemployment rate will causeA) no change in the real wage.B) a reduction in the real wage.C) an increase in the real wage.D) an upward shift of the PS curve.Answer: ADiff: 212) Suppose the aggregate production function is given by the following: Y = AN. Given this information, we know that labor productivity is represented by which of the following?A) 1/AB) AC) 1/ND) N/YAnswer: BDiff: 213) Suppose the aggregate production function is given by the following: Y = N. Given this information, we know that labor productivity is represented by which of the following?A) 1/NB) NC) N/YD) 1Answer: DDiff: 214) A reduction in unemployment benefits will tend to cause which of the following?A) an upward shift in the WS curveB) a downward shift in the WS curveC) an upward shift in the PS curveD) a downward shift in the PS curveE) none of the aboveAnswer: BDiff: 215) An increase in the minimum wage will tend to cause which of the following?A) an upward shift in the WS curveB) a downward shift in the WS curveC) an upward shift in the PS curveD) a downward shift in the PS curveE) none of the aboveAnswer: ADiff: 216) Suppose that increased international trade makes product markets more competitive in the U.S. Given this information, we would expect to observe which of the following?A) an upward shift in the WS curveB) a downward shift in the WS curveC) an upward shift in the PS curveD) a downward shift in the PS curveE) none of the aboveAnswer: CDiff: 217) With the real wage on the vertical axis and employment (N) on the horizontal axis, we know thatA) the WS curve is upward sloping.B) the WS curve is downward sloping.C) the PS curve is upward sloping.D) the PS curve is downward sloping.Answer: ADiff: 218) Based on our understanding of the labor market model presented in Chapter 6, we know that an increase in the minimum wage will causeA) an increase in the equilibrium real wage.B) a reduction in the equilibrium real wage.C) a reduction in the natural rate of unemployment.D) both B and CAnswer: ADiff: 219) Based on our understanding of the labor market model presented in Chapter 6, we know that an increase in the markup will causeA) an increase in the equilibrium real wage.B) a reduction in the equilibrium real wage.C) a reduction in the natural rate of unemployment.D) both B and CAnswer: BDiff: 220) Based on our understanding of the labor market model presented in Chapter 6, we know thata reduction in the markup will causeA) an increase in the equilibrium real wage.B) a reduction in the equilibrium real wage.C) an increase in the natural rate of unemployment.D) a reduction in the natural rate of unemployment and no change in the real wage.Answer: ADiff: 221) For this question, assume that Y = N.

Based on our understanding of the labor market model presented in Chapter 6, we know that a reduction in the markup will causeA) an increase in the natural level of output.B) a reduction in the natural level of output.C) no change in the natural level of output.D) a reduction in the natural level of employment.Answer: ADiff: 223) Based on wage setting behavior, we know that an increase in the unemployment rate will causeA) no change in the real wage.B) a reduction in the real wage.C) an increase in the real wage.D) an upward shift of the WS curve.Answer: BDiff: 224) Based on price setting behavior, we know that an increase in the unemployment rate will causeA) no change in the real wage.B) a reduction in the real wage.C) an increase in the real wage.D) an upward shift of the PS curve.Answer: ADiff: 225) An increase in unemployment benefits will tend to cause which of the following?A) a downward shift in the WS curveB) an upward shift in the PS curveC) an upward shift in the WS curveD) a downward shift in the PS curveE) none of the aboveAnswer: CDiff: 226) A reduction in the minimum wage will tend to cause which of the following?A) an upward shift in the WS curveB) a downward shift in the WS curveC) an upward shift in the PS curveD) a downward shift in the PS curveE) none of the aboveAnswer: BDiff: 227) Explain what effect a reduction in the unemployment rate will have on the real wage based on: (1) the WS relation; and (2) the PS relation.Answer: A reduction in the unemployment rate will increase bargaining power, increase the nominal wage, and therefore increase the real wage based on wage setting behavior. Changes in the unemployment rate have no effect on the real wage based on price setting behavior.Diff: 228) First, explain what the PS relation represents. Second, explain why it has its particular shape. Answer: The PS relation illustrates the effect of changes in the unemployment rate on the real wage implied by the price-setting behavior of firms. Firms set prices as a markup over their marginal cost of producing goods. Given that the marginal cost is assumed to be independent of the level of employment (and, therefore, the unemployment rate), changes in u will have no effect on the price firms set and, therefore, on the real wage based on PS behavior.Diff: 229) Graphically illustrate (using the WS and PS relations) and explain the effects of an increase in the markup on the equilibrium real wage, the natural rate of unemployment, the natural level of employment, and the natural level of output.Answer: An increase in the markup will cause firms to raise the price given the nominal wage. This will cause the real wage based on price setting behavior to decrease; this is represented by a downward shift in the PS curve. This reduction in the real wage will also occur with an increase in the unemployment rate. So, the natural rate of unemployment will rise and the natural level of employment and, therefore, output will fall. The equilibrium real wage will also be lower. Diff: 230) Graphically illustrate (using the WS and PS relations) and explain the effects of an increase in the minimum wage on the equilibrium real wage, the natural rate of unemployment, the natural level of employment, and the natural level of output.Answer: An increase in the minimum wage will cause the nominal wage based on wage setting behavior to increase; this is represented as an upward shift in the WS relation. As the nominal wage increases, firms will respond by increasing the price level so we will observe no change in the equilibrium real wage. We will observe an increase in the natural rate of unemployment and a reduction in both the natural level of employment and output.Diff: 231) Based on your understanding of the labor market model presented by Blanchard (i.e., the WS and PS relations), explain what types of policies could be implemented to cause a reduction in the natural rate of unemployment.Answer: The natural rate of unemployment will change whenever either the PS or WS relations change. To reduce the natural rate, policy makers could implement polices that: (1) reduce unemployment benefits; (2) reduce the minimum wage; or (3) increase competition in product markets.Diff: 232) Explain how a reduction in the unemployment rate will affect bargaining power and nominal wages.Answer: As the unemployment rate decreases, it is easier for individuals to find employment at other firms. So, workers' bargaining power will increase. As bargaining power increases, the nominal wage will increase.Diff: 233) Graphically illustrate (using the WS and PS relations) and explain the effects of a reduction in the markup on the equilibrium real wage, the natural rate of unemployment, the natural level of employment, and the natural level of output.Answer: A reduction in the markup will cause firms to reduce the price given the nominal wage. This will cause the real wage based on price setting behavior to increase; this is represented by a upward shift in the PS curve. This increase in the real wage will also occur with an decrease in the unemployment rate. So, the natural rate of unemployment will decrease and the natural level of employment and, therefore, output will increase. The equilibrium real wage will also be higher.Diff: 234) Graphically illustrate (using the WS and PS relations) and explain the effects of a reduction in the minimum wage on the equilibrium real wage, the natural rate of unemployment, the natural level of employment, and the natural level of output.Answer: A reduction in the minimum wage will cause the nominal wage based on wage setting behavior to decrease; this is represented as an downward shift in the WS relation. As the nominal wage deceases, firms will respond by reducing the price level so we will observe no change in the equilibrium real wage. We will observe a decrease in the natural rate of unemployment and an increase in both the natural level of employment and output.Diff: 235) Explain what effect an increase in the unemployment rate will have on the real wage based on: (1) the WS relation; and (2) the PS relation.Answer: An increase in the unemployment rate will decrease bargaining power, decrease the nominal wage, and therefore decrease the real wage based on wage setting behavior. Changes in the unemployment rate have no effect on the real wage based on price setting behavior.Diff: 2。
