QUESTION 8Which of the following is true about long-run equilibrium in a monopolistically competitive market?
a. Firms earn zero economic profit because price equals long-run average cost, but the equilibrium is not allocatively efficient because price exceeds the marginal cost of the last unit produced.
b. They may earn negative, zero, or positive economic profit because monopolistically competitive firms are price takers.
