b. an explicit cost

c. an implicit cost

12)

Tamati owns a car-detailing business. In summer demand for detailing is highest. Tamati hires students to help him detail cars in summer. If Tamati works by himself he can detail 20 cars in a week. If he hires one worker, the two of them will detail 35 cars over a week. A second worker increases that to 47 cars. The third worker increases that to 57 cars. The fourth worker increases the total to 65 cars.

The marginal product of the first worker is

Select one:

a. 8 cars per week

b. 15 cars per week

c. 12 cars per week

d. 10 cars per week

Solutions

Expert Solution

Answer 1: a. equal to the monopoly price.

if two firms form a cartel, then both will charge a price at the level where prices are equal to the monopoly price. Thus, both firms will agree to charge monopoly price from the consumer.It will not charge perfecltly competitive price because it will reduce profits.

Answer 2: Option d. continue to operate as long as average revenue exceeds average fixed cost.

Since the revenue of the firm is greater than cost of the firm, thus the firm will continue to operate. When the price falls below the minimum point of the average variable cost of the firm, the firm will be earning losses.

Answer 3: Option b. Price exceeds average total cost for existing firms in the market.

New firrms will enter the market when price that the firm charges is greater than the average total cost of the firms and thus the firm is earning super normal profits in this case.

Answer 4: Option d. Producer profits must fall in the long run.

An increase in demand will induce the entry of other firms in the industry. As new firms will enter the industry, the prices will fall with the rightward shift of the supply curve and profits of the firm will fall in the long run.
