B
Suppose that the market for candy canes operates under conditions of perfect competition, that it is in long-run equilibrium, and that the price of each candy cane is $0.10.

C. is less than $0.10. D. is greater than $0.10.

C
If a monopolist is producing a quantity that generates MC < MR, then profit: A. can be increased by decreasing production. B. is maximized. C. can be increased by increasing production. D. is maximized only if MC = P.
C
In the long run: A. the firm considers all factors as fixed B. production is always greater than zero C. the firm considers all factors as variable D. production choices are more limited than in the short run
