From Example 1.2 in the textbook, Pindyck and Rubinfeld distinguish between the mass market and dealer market for bicycles. Although there are many dealers in the U.S. and only a few mass merchandisers, we should expect the dealer market to be somewhat less competitive than the mass market. Why?

Due to their differences in quality and performance, dealer bicycles are not close substitutes. Dealers are small sellers and have little control over bicycle prices. A and B are correct. B and C are correct.

Why does cooperative behavior break down in games with finite endpoints? Finite games have the same outcomes as one-period games, and cooperation is not possible in one-period games. Each player has an incentive to deviate from a cooperative strategy during the last period. A Nash equilibrium is only possible in mixed strategies in finite repeated games, but all of the probabilities assigned to particular strategies approach zero as the number of finite game periods becomes large. Thus, we cannot evaluate the expected payoffs in these games. A Nash equilibrium in pure strategies is not possible in finite repeated games.

Each player has an incentive to deviate from a cooperative strategy during the last period.

La Tortilla is the only producer of tortillas in Santa Teresa. The firm produces 10,000 tortillas each day and has the capacity to increase production to 100,000 tortillas each day. La Tortilla has made a large profit for years, but no other firm has chosen to compete in the Santa Teresa tortilla market. La Tortilla has been able to deter entry because if other firms were to enter the market it would greatly step-up production and reduce price. La Tortilla behaves like a Stackelberg firm. La Tortilla's behavior is inconsistent with economic theory. La Tortilla has been successful because of its credible threat. La Tortilla must have other barriers to entry to protect its monopoly power.

Plastic and steel are substitutes in the production of body panels for certain automobiles. If the price of plastic increases, with other things remaining the same, we would expect: the demand curve for plastic to shift to the left. the demand curve for steel to shift to the right. the demand curve for steel to shift to the left. the price of steel to fall. nothing to happen to steel because it is only a substitute for plastic.

A "mixed strategy" equilibrium means that one player has a dominant strategy, and one does not. the equilibrium strategy involves alternating between a dominant strategy and a Nash strategy. one player has a pure strategy, and one does not. the strategies chosen by the players represent different behaviors. the equilibrium strategy is an assignment of probabilities to pure strategies.

the equilibrium strategy is an assignment of probabilities to pure strategies.

The amount of output that a firm decides to sell has no effect on the market price in a competitive industry because the market price is determined (through regulation) by the government the demand curve for the industry's output is downward sloping the short run market price is determined solely by the firm's technology the firm's output is a small fraction of the entire industry's output the firm supplies a different good than its rivals

the firm's output is a small fraction of the entire industry's output

The substitution effect of a price change for product X is the change in consumption of X associated with a change in the price of X, with the prices of other goods changing by the same percentage as that for product X. the price of X, with the level of real income not considered. the price of X, with the level of utility held constant. income, with prices of other goods held constant.

the price of X, with the level of utility held constant.

A supply curve reveals: the quantity of output consumers are willing to purchase at each possible market price. the quantity of output that producers are willing to produce and sell at each possible market price. the maximum level of output an industry can produce, regardless of price. the difference between quantity demanded and quantity supplied at each price.

the quantity of output that producers are willing to produce and sell at each possible market price.

The demand curve facing a perfectly competitive firm is the same as its average revenue curve and its marginal revenue curve. not defined in terms of average or marginal revenue. the same as its marginal revenue curve, but not its average revenue curve. the same as its average revenue curve, but not the same as its marginal revenue curve. not the same as either its marginal revenue curve or its average revenue curve.

Scenario 13.1: You are negotiating with your florist over the price of flowers for your wedding. You value the floral arrangements at $500. The florist's cost for the arrangement is $200. You finally settled on a price of $250. Refer to Scenario 13.1. If your negotiated price had been $350 instead of $250, the sum of consumer surplus and producer surplus would be: more than what would have accrued at the $250 price. the same as what would have accrued at the $250 price. less than what would have accrued at the $250 price. None of the above is necessarily correct.

the same as what would have accrued at the $250 price.

If any of the assumptions of perfect competition are violated, graphs with downward-sloping demand curves cannot be used to study the firm. there may still be enough competition in the industry to make the model of perfect competition usable. one must use the monopoly model instead. graphs with flat demand curves cannot be used to study the firm. supply-and-demand analysis cannot be used to study the industry.
