Information: Suppose the firm has 500 employees each working a standard workweek of 40 hours. The typical worker earns a real wage of 10 per hour and receives another 200 in weekly benefits and training, 150 of which are quasi-fixed costs to the firm. The marginal expense an employer faces when increasing its average workweek by an hour (MEH) is approximately the sum of wage and variable benefit costs (on a per-hour basis) multiplied by he number of employees. Assuming...

Suppose there are two firms, 1 and 2, each with M C = AC = 10. They each choose quantities of output, y1 and y2. The market demand is p= 70−2y, where y=y1+y2. Each firm discounts the future at rate δ <1per period. a. [6 marks] First calculate the Cournot equilibrium outputs. Call these y∗1 and y∗2. b. [4 marks] Next, calculate how much each firm would produce if the two firms colluded to act as a monopoly. Call these...
