If monopolistically competitive firms have some control over the prices they charge, why do they experience zero economic profits in the long run? What does this mean for society as a whole in terms of costs to produce the product and resources allocation?
Explain why a firm maximizes its total profits by producing where MC = MR. To answer this question completely, you should explain why output levels greater than and less than the level where MC = MR do not maximize profits.
