Solutions

Expert Solution

d. price takers

Explanation :

Perfectly competitive firm produce homogeneous product and there are many firms in the market. There is free entry and exit. They charge price what market price is. So they are price takers. Because they have no market power they are price taker.

d. MC = MR

Explanation:

Firm maximises it's profit where MR equals MC. Marginal revenue is the extra revenue generated by the firm with selling one more extra unit and marginal cost is the extra cost occurred with the production of one more extra unit. So when MR is greater than MC, extra unit will be profitable. And when MR is less than MC, that extra unit of production is not profitable. So firm will maximise its profit by producing where MR equals MC.

c. imperfect information

Explanation :

In perfect competition, there is perfect information. There is free entry and exit. And they produce homogeneous product.

a. zero economic profits.

Explanation :

Perfectly competitive firm earns zero economic profit in long run. When there is positive economic profit, new firm have incentive to enter the market. When there is negative profit, existing firm will exit the industry. At the end of this entry and exit process, firms will earn zero economic profit in long run.

b. Price x Quantity

Explanation :. Total revenue is equals to price multiply by quantity produced.
