a. When the firm profit maximizes, what is the amount of the firm's profit or loss? Is this firm
in the short run or long run equilibrium and why?
b. Assume that this firm is typical of other firms in the industry. Given the profit (or loss) that
firms in the market are earning, what adjustments will happen in the long run for the
market to reach long run equilibrium?
c. What is the similarity between the long run equilibrium of this monopolistically
competitive firm from a perfectly competitive firm? What is (are) the difference(s) in their
long run equilibrium situation (consider price and output levels)?
d. Is this firm operating with an excess capacity in the short run? Why? When the firm
transitions to the long run equilibrium, will it be operating with an excess capacity or not?
Explain.
