a) What 4 outcomes will a binding minimum wage have, and what 1 outcome has 2 possibilities.
b) When is a perfectly competitive firm in the short run? What 3 outcomes can a firm face in the short run, and what would be each result moving into the long run?
b. A perfectly competitive firm is in short-run equilibrium when marginal revenue is same as marginal cost and price is same as marginal revenue because the price is fixed and constant.
Outcome 1= Loss when P < ATC
Outcome 2 = indifferent between shutdown and produciton when P = AVC
Outcome 3 = Profit when P > ATC
I long run, P = ATC and there is no profit no loss situation because firms who were in loss exit the industry whereas those earning profit who entered remain at zero profit.
