Automobile manufacturers commonly sell new car models at the full suggested retail price during the first few years the car is on the market, and they do not offer rebates or discounts. After the initial sales period, the manufacturers typically offer rebates or discounts on these models. The marginal cost of manufacturing the cars is constant across time. Which of the following statements is true? The firms practice peak-load pricing by charging a higher price in the initial sales period. The marginal revenue from buyers who purchase these cars after the initial sales period must be lower that the marginal revenue from early buyers. Early buyers have higher reservation prices for the new models, and the manufacturers maximize profits by charging these buyers a higher price. To maximize profits, the firms equate the buyers' reservation prices across time.

What happens to the profit-maximizing cartel price and quantity if the marginal cost of production declines? The sellers are no longer price takers, so the change in marginal cost has no impact on the cartel outcome. The sellers retain the same pricing strategy and capture higher per-unit profits. The cartel price increases and market quantity declines. If demand is downward sloping, the optimal cartel price should decline and the market quantity should increase.

If demand is downward sloping, the optimal cartel price should decline and the market quantity should increase.

Which of the following statements is true? If marginal costs are constant, then it is optimal to advertise until the last dollar spent on advertising generates one additional dollar of sales. If the advertising elasticity of demand is positive, then the demand curve must be upward sloping. If the advertising elasticity of demand declines and consumer demand becomes more price elastic, then the optimal advertising-to-sales ratio declines. If the demand curve shifts leftward as the advertising expenditure increases, then the advertising elasticity of demand is positive.

If the advertising elasticity of demand declines and consumer demand becomes more price elastic, then the optimal advertising-to-sales ratio declines.

In the Stackelberg model, suppose the first-mover has MR = 15 - Q1, the second firm has reaction function Q2 = 15 - Q1/2, and production occurs at zero marginal cost. Why doesn't the first-mover announce that its production is Q1 = 30 in order to exclude the second firm from the market (i.e., Q2 = 0 in this case)? This is a possible outcome from the Stackelberg duopoly under these conditions. In this case, MR is negative and is less than MC, so the first-mover would be producing too much output. In this case, MR is negative and is less than MC, so the first-mover would be producing less than the optimal quantity. We do not have enough information to determine if this is an optimal outcome for this case.

In this case, MR is negative and is less than MC, so the first-mover would be producing too much output.

MRA = MRB = MC.

The authors explain that the international copper cartel (CIPEC) has been largely ineffective in raising the price of copper in world markets, and the reason is mainly due to the relatively elastic demand for copper. Suppose the cartel recognized that there are multiple uses for copper, and some of the uses have few substitute products (e.g., copper electrical wire) while others have several close substitutes (e.g., copper water pipes). If cartel attempted to raise the price of copper in one of these sub-markets, which market should the cartel choose? Market with several close substitutes because demand is more elastic. Market with few close substitutes because demand is more elastic. Market with several close substitutes because demand is more inelastic. Market with few close substitutes because demand is more inelastic.

If the price elasticity of demand for steel is greater abroad than it is in Japan, which of the following will be correct? The Japanese firm will sell steel at a higher price abroad than they will charge domestic users. The Japanese firm will sell more steel abroad than they will sell in Japan. Insufficient information exists to determine whether the price or quantity will be higher or lower abroad. The Japanese firm will sell more steel in Japan than they will sell abroad. The Japanese firm will sell steel at a lower price abroad than they will charge domestic users.

The Japanese firm will sell steel at a lower price abroad than they will charge domestic users.

The authors explain that the international copper cartel (CIPEC) has been largely ineffective in raising the price of copper in world markets, and the reason is mainly due to the relatively elastic demand for copper. Suppose the cartel recognized that there are multiple uses for copper, and some of the uses have few substitute products (e.g., copper electrical wire) while others have several close substitutes (e.g., copper water pipes). To increase profits, the cartel could raise the price of copper in the sub-markets with relatively inelastic demand. What else would the cartel have to do in order to make the cartel's action effective? The cartel would have to seek permission from the U.S. Department of Justice. The cartel would have to find a way to keep the buyers in the low-price market from reselling the copper to buyers in the high-price market. The cartel would have to get the cooperation of all other copper producers in order to raise the price by some positive amount. none of the above

The cartel would have to find a way to keep the buyers in the low-price market from reselling the copper to buyers in the high-price market.

Why are many oligopolistic market outcomes conveniently described by a Prisoners' Dilemma? The firms can always achieve the outcome that maximizes joint outcomes.

What is the potential drawback if firms follow a price leadership model in an actual market? Disputes about which firm should be the price leader may lead to price wars. Excessive price signalling may force all of the firms to adopt price-taking strategies, which reduces overall profits among the firms. Signalling efforts increase the firms' fixed costs of production. The price leader's behavior may be interpretted as collusion and be subject to antitrust sanctions.

The price leader's behavior may be interpretted as collusion and be subject to antitrust sanctions.

Which of the following statements about setting optimal two-part tariffs for many consumers is NOT true?

The profit from the entrance fee (tariff) is a concave function of the tariff because it first increases and then decreases as the tariff increases. The number of buyers (entrants) declines as the entrance fee (tariff) increases.
