1. A perfectly competitive firm is in long run equilibrium. Suppose that there is an increase in population in the market served by this firm.
a. In the short run we can expect the market price for the good sold in this market to ___________________________.
b. In the short run we can expect the quantity produced by this firm to __________________________ __________.
c. In the short run we can expect the quantity produced by the market to ______________________________.
d. In the long run if this is a constant cost industry the market price will be (higher, lower, or equal to) the original market price.
e. In the long run given this information, we can expect the number of firms in the industry to (increase, decrease, or remain unchanged).
2. Consider a constant cost perfectly competitive industry where the market supply and demand curves are given as
Market Demand: P = 40 - (2/5)Q
Market Supply: P = 10 + (1/5)Q
and the representative firm's total cost curve and marginal cost curve are given as
TC = 25 + 10q + q2
MC = 10 + 2q
Suppose this industry is in long run equilibrium.
a. In long run equilibrium what quantity will the representative firm produce?
b. In long run equilibrium what is the market price?
c. In long run equilibrium how many firms are in the industry?
d. In long run equilibrium what is the value of total surplus in the market?
3. In the class we have talked about how a firm profit maximizes by producing that level of output where MR = MC. In words explain why this is true?
