b. Firms in both types of industries produce similar but not identical products

c. Barriers to entry in both industries are large

d. Firms in both types of industries produce identical products

Match the following.

constant-cost industry A market structure in which a large number of firms sell a homogenous product or service with no restrictions on entry or exit and each firm is a price-taker.
increasing-cost industry The demand facing a price-taking firm.
long-run equilibrium A firm produces zero output but must still pay its fixed costs.
marginal revenue product Price below which a firm shuts down in the short run.
perfect competition All firms produce where price equals long-run marginal cost, and economic profits are zero.
perfectly elastic demand Industry in which input prices rise as all firms in the industry expand output.
shut down Industry in which input prices remain constant as all firms in the industry expand output.
the shut-down price The additional revenue earned by hiring one more unit of a variable input.

 

1. Patent laws:
reduce incentive to innovate by restricting market entry
reduce incentive to innovate by making it difficult to use thepatented innovation
increase incentive to innovate by restricting entry into amarket
increase incentive to innovate by giving a firm permanent andexclusive production rights


2. Which of the following is true of marginal revenue for amonopolist that charges a single price?
P = MR because there are no close substitutes for the monopolist'sproduct.
P > MR because the monopolist must decrease price on all unitssold in order to sell an additional unit.
P < MR because the monopolist must decrease price on all unitssold in order to sell an additional unit.
AR = MR because there are no close substitutes for the monopolist'sproduct.


3. Negative marginal revenue means that
total revenue is decreasing as output increases
the firm is maximizing its total revenue
the firm is maximizing its economic profit
total revenue is increasing at a decreasing rate as outputincreases


4. A profit-maximizing monopolist produces an output level atwhich
marginal revenue is the greatest distance from marginal cost
price is less than marginal cost
the value to society of the last unit produced equals marginalcost
marginal revenue equals marginal cost


5. Compared to a perfectly competitive market, a monopoly tends toproduce
more output and charge a higher price
the same amount of output, but charge a higher price
less output and charge a higher price
less output and charge the same price


6. Monopolistic competition is best described as
many firms with some control over price, and some productdifferentiation
many firms with no control over price, producing identicalproducts
a few firms with some control over price, producing highlydifferentiated products
a few firms with no control over price, producing similarproducts


7. Which of the following characteristics does perfect competitionshare with monopolistic competition?
price-taking firms
zero long-run economic profit
homogeneous product
some barriers to entry


8. Monopolistically competitive firms do not achieve productiveefficiency because
entry of firms raises production costs in the long run
barriers to entry allow profit to be earned in the long run
price is greater than marginal cost at the profit maximizing outputlevel
profit is maximized at a quantity where average total cost is notminimized


9. There are multiple models of pricing behavior in oligopolisticmarkets because
it is difficult to predict how rival firms will react to anypricing decision
the demand curve slopes upward for these firms
firms could earn profit in the long run unlike other markets
price has a direct impact on profit for a firm in oligopoly


10. Which of the following is likely to occur when a two-persongame can be played repeatedly?
Collusion and cooperation among the players
The prisoner's dilemma
