11.  Consider a monopolistically competitive industry in long-run equilibrium. Will this industry be productively efficient?

a.      Yes. Since the firms are in long-run equilibrium, they will all be producing at the minimum of their LRAC curves.

b.     Yes. Since the firms are in long-run equilibrium, they will all be operating on their LRAC curves.

c.      Yes. In long-run equilibrium, each firm is producing at an output level where price is equal to marginal cost.

d.     No. Firms are selling their output at a level where price exceeds marginal cost and thus, by definition, cannot be productively efficient.

e.     No. Since firms are selling differentiated products and there is no industry-wide price, we cannot conclude that marginal cost will be equated across all firms.
