Firm änd Market
In this exercise and the next, we compare a perfectly com etitive market to a monoj.oly. First,
consider a perfectly competitive widget industry that h s adjusted to long-run equilibrium:
Each firm earns zero economic profit, so there is no incen ve for firms either to enter or to exit.
Each firm has chosen a (short run) plant size that allows it to achieve the minimum achievable
long-run average cost, so there is no incentive for any firm either to enlarge cr to contract its
scale of operation. Let Q = industry output and q = the output of any single firm.
There are n identical firms:
Q = nq
Each firm's short-run total cost is:
TC = 90 + 2.5q?
Market demand (D) for the product is:
P = 60 -- 2Q
Write the equations of each firm's marginal cost, average v. riable cost, and average cost.
MC =

AC =
b. Find the firm's equilibrium level of output (where MC = AC) Calculate equilibrium price and the
corresponding values of AVC and AC. (Use the table to ider ify some values for AC.)
