Unit 6 Lab: The figure depicts the efficiency wage equilibrium of a worker and a firm. Based on this information, which of the following statements is correct? a) At A, given that the firm pays the hourly wage of $12 the workers best response is to exert an effort of 0.5 b) At A given that the worker exerts an effort level of 0.5, the firm's best response is to offer the hourly wage of $12 c) This is the sequential game where the firm chooses its action given the workers best response to its actions. Therefore, the worker receives no rent d) The employer makes profits by coercing the worker to put in some effort

A (At A, given that the firm pays the hourly wage of $12, the workers best response is to exert an effort of 0.5. Explanation: Definition of workers best response curve.

Unit 6 Lab: As the hourly wage rises, the worker's best response function(with effort on the vertical axis and wages on the horizontal axis) becomes flatter because: a) The disutility of work at the level chosen by the worker increases b) The workers goodwill towards the employer increases c) The marginal effect of effort on production is diminishing

A (The disutility of work at the level chosen by the worker increases) Explanation: As hourly wage rises the quality of work at the level chosen, influenced by the wages becomes greater for the maximization of profit for both employee and employer.

A (The firm's profit level falls.) Explanation: Higher unemployment benefits means that the workers' reservation wage will be higher, so the firm's profit level falls.

Unit 6 Lab: In the figure, suppose that unemployment benefits of $5 per hour are introduced. Which of the following are true in this situation? a) If the unemployment benefit stops after the first 22 weeks of unemployment, the total employment rent over the expected duration of unemployment is $3,850 b) If the unemployment benefit is lowered to $3 per hour but extended to the first 30 weeks of unemployment, the employment rent over the expected duration of unemployment will be higher than when there is a $5 per hour benefit for 22 weeks c) If the unemployment benefit is now $5 per hour again, but the disutility of an hour of effort has now fallen to zero, the employment rent per hour will be $5 per hour while the benefit is received, and $7 per hour thereafter

B ( If the unemployment benefit is lowered to $3 per hour but extended to the first 30 weeks of unemployment, the employment rent over the expected duration of unemployment will be higher than when there is a $5 per hour benefit for 22 weeks) Explanation: The unemployment rent under $5 per hour unemployment benefit employment rate under the $3 per hour benefit

Unit 6 Lab: For production to take place in the firm, the workers must supply some effort. Suppose that with the status quo best response curve in the figure below, the firm chooses the wage to minimize the cost of effort, and the worker's best response is an effort level of 0.6. Which of the following statements must be true in equilibrium? a) If the disutility of effort rises, then effort will fall b) If unemployment rises, then the wage will fall c) Any combination of e and w that is both on the isocost line and the best response curve is a Nash equilibrium

B (If unemployment rises, then the wage will fall) Explanation: Unemployment provides less jobs in the workforce resulting in the wage falling due to the supply and demand curve.

Unit 6 Lab: Maria earns $15 per hour in her current job and works 40 hours a week. Her disutility of effort is measured as $1 per hour of work. In the case that she loses her job, she receives $5 per hour unemployment benefit. Additionally, being unemployed has physiological and social costs which is a disutility equivalent to $2 per hour. Then, a) The employment rent per hour is $3 b) Maria's employment rent if she can get another job with the same wage rate after 44 weeks of being unemployed is more than $6,160 c) Maria's employment rent if she can only get a job at the same wage rate after 44 weeks of being unemployed is less than $7,700

B (Maria's employment rent if she can get another job with the same wage rate after 44 weeks of being unemployed is more than $6,160.) Explanation: The unemployment rate is 11 x (44 x 40)= $19,360

Unit 6 Lab: Which of the following statements is true: a) A labor contract transfers ownership of the employee from the employee to the employer b) The office where the employee works is a relation-specific asset because the employee cannot use it after leaving the firm c) In a labor contract, one side of the contract has the power to issue orders to the other side, but this power is absent from a sale contract. d) A firm is a structure that involves decentralization of power to the employees

C (In a labor contract, one side of the contract has the power to issue orders to the other side, but this power is absent from a sale contract. Explanation: A labor contract gives the employer the ability to direct the activities of employees. A sale contract transfers property rights.

Unit 6 Lab: If unemployment benefits increase: a) A workers effort increases because the employment rent increases b) Effort decreases because the disutility of effort decreases c) The employment rent will fall unless the firm raises the wage

C (The employment rent will fall unless the firm raises the wage) Explanation: The lost income relative to being employed falls, so the employment rent decreases, unless the firm increases the wage.

Unit 6 Lab: The figure depicts the efficiency wage equilibrium of a worker and a firm. According to his figure: a) At C, the marginal rate of the substitution (MRS) between higher wage cost and higher effort exceeds the marginal rate of transformation (MRT) b) At B, the MRS is higher than the MRT c) The firm would maximize its profits by paying an hourly wage that is $6 above the workers reservation wage d) The firm is able to increase its profit from those attained at A by inducing the worker to exert higher effort in return for a higher wage

C (The firm would maximize its profits by paying an hourly wage that is $6 above the workers reservation wage) Explanation: The firm's profit-maximizing point is A, where it pays an efficiency wage of $12 per hour. This is $6 above the reservation wage of $6)

Unit 6 Lab: Consider a worker's best response curve in the labor discipline model. Currently the firm chooses to pay 12 per hour to minimize the cost of effort, which induces an effort level of 0.6 from the worker. Now consider a rise in the unemployment benefit. Then: a) At the wage rate of $12 per hour the worker will now exert more than 0.6 of effort b) The firm can lower the wage rate to below $12 to maintain the effort level of 0.6 c) The firm's new wage offer that minimizes the cost of effort will be higher than $12 d) The firm's maximum units of effort per dollar of wage cost will be higher than before the rise in the unemployment benefit

C (The firm's new wage offer that minimizes the cost of effort will be higher than $12) Explanation: With the rightward shift in the best response curve, the point of tangency with the highest feasible isocost would shift to the right i.e. the firm will offer a higher equilibrium wage rate.

Unit 6 Lab: Consider isocost lines drawn on a graph with hourly wage on the horizontal axis and effort per hour on the vertical axis. Which of the following statements is correct? a) Isocost lines intersect the horizontal axis at the reservation wage b) The slope of the isocost line is the employers marginal rate of transformation of higher wages into the worker effort c) Steeper isocost lines represent higher cost unit of effort d) For an isocost lines with a slope of 0.07, the cost of unit of effort is $14.3

D (For an isocost lines with a slope of 0.07, the cost of unit of effort is $14.30) Explanation: The slope of the isocost lines represents the units of effort per dollar of wage cost , which is the inverse of the cost per unit of effort. That latter is therefore 1/0.07 = $14.30.

Unit 6 Lab: Consider the labor discipline model applied to two countries, a high-wage country and a low-wage country. Assume that the high-wage country has a higher unemployment benefit. Consider a firm producing the same product in both countries.

D (The threat of outsourcing from the high-wage country to the low-wage country would raise the workers' best response curve in the high-wage country.) Explanation: Due to the unemployment rate being higher in the high-wage country it would give the workers an incentive to put more effort into their work. Especially, if the potential to outsource from a cheaper country would cause a loss of work for the high-wage country they would want to put forth more effort at each level of wages.

Unit 6 Lab: Which of the following is correct regarding involuntary employment: a) When a firm sacks a worker against her wishes but she can get another job immediately, there is involuntary unemployment b) When there is involuntary unemployment, the employment rent is zero c) When there is no involuntary unemployment, firms must be employing workers without ever dismissing them d) There must be involuntary unemployment in an efficiency wage equilibrium

D (There must be involuntary unemployment in an efficiency wage equilibrium) Explanation: In an efficiency wage equilibrium, both wages and involuntary unemployment have to be high enough to ensure that there is enough employment rent for workers to put effort in.
