Suppose there is a perfectly competitive industry where all the firms are identical with identical cost curves.

Furthermore, suppose that a representative firm’s total revenue is given by the equation TR = q.p; where q is the quantity of output produced by the firm and p the market price (=P).

The market demand for this product is given by the equation P = 5000 – 9Q where Q is the market quantity.

In addition you are told that the market supply curve is given by the equation P = 1000 + Q.

a. What is the equilibrium quantity and price in this market given this information?

b. The firm’s MC equation based upon its TC equation is MC = 5q + 4. Given this information and your answer in part (a), what is the firm’s profit maximizing level of production, total revenue, total cost and profit at this market equilibrium?

Is this a short-run or long-run equilibrium? Explain your answer.

c. Given your answer in part (b), what do you anticipate will happen in this market in the long-run?
