A. If the firm can sell its output at a price of $5 per unit, then how much labor will be hired at a weekly wage rate of $500? Show why this quantity of labor is best for the firm. (12 points)

B. Suppose a minimum hourly wage of $15 is imposed. Now, how much labor will be hired? Show why this quantity of labor is best for the firm. In this case is labor demand elastic or inelastic? Demonstrate and explain. (8 points)

Solutions

Expert Solution

A. The output is sold at a price of $5 per unit. Find the marginal product as the addition to the total product and then find the marginal revenue product which is = MP x price

Now see that optimum rule is to hire worker till MRP = wage rate, then a total of 4 workers will be hired at a weekly wage rate of $500. This is the bese number because beyond this the profit is maixmum in this case.

B. Suppose a minimum hourly wage of $15 or $15*40 = $600 weekly wage is imposed. At this rate 3 labor units will be hired because then the profit is maximum at L = 3 Labor demand is inelastic because wage rate is increased by 100 but demand is reduced by 1 labor unit.
