This table shows a game played between two players, A and B. The payoffs in the table

a.In the long run, there are no fixed costs.
b.Marginal cost is independent of fixed costs.
c.Economies of scale is a short-run concept.
d.Diminishing marginal product explains increasing marginal cost.
4) Figure 16-2. The figure is drawn for a monopolistically competitive firm.

c.it increases the reward for working hard, resulting in people producing more goods
and services.
d.those who earn more income pay less in taxes.
9) A country club usually only allows members to purchase tickets for its celebrity golf
tournament, but the club is considering allowing non-members to purchase tickets this
year. The demand and supply schedules are as follows:
If both members and non-members are allowed to purchase tickets to this year's
celebrity golf tournament and the country club sets the ticket price at $20, then there
will be
a.a shortage of 300 tickets.
b.a surplus of 300 tickets.
c.300 tickets sold.
d.600 tickets unsold.

is represented by area
a.A.
b.A+B+C.
c.D+H+F.
d.F.

long-run the price of its product exceeds its
a.average revenue.
b.average total cost.
c.marginal cost.
d.None of the above is correct.

a.has a higher cost of signaling (advertising) than does a firm with an inferior product.
b.has more to gain by signaling (advertising) than does a firm with an inferior product.
