A perfectly competitive firm operates in a market where P = $4. The firm's revenue is ______ and marginal revenue is ________.

A)	R = 4q; MR = 4

B)	R = 4; MR = 4q

C)	R = MR = 4

D)	R = 4/q; MR = 4q

Solutions

Expert Solution

R = 4q ; MR =4

Revenue refers to the amount received by a firm from the sale of a given quantity of a commodity in the market.

Revenue = Price*Quantity

Price = $4

Let quantity be q

Revenue = 4*q = 4q

In the perfectly competitive market, each firm is a price taker. All the firms have to accept the same price as determined by market forces of demand and supply. As a result, uniform price prevails in the market. It means, revenue from every additional unit (known as MR) is equal to price of the product i.e. P= MR. Price = $4. Therefore P = MR = 4.

A firm operates in a perfectly competitive market where the market price is p=$200. The firm’s total cost of production is given by the following equation: TC(q) = 250 + 10q2 + 20q, where q is the quantity supplied. When this firm maximizes profit, what is the optimal quantity to produce in the short run and what will happen in the long run? a) q=0 (shut-down) both in the long run and in the short run b) q=9 in the...
