Mexico and the members of OPEC produce crude oil. Realizing that it would be in their best interests to form an agreement on production goals, a meeting is arranged and an informal, verbal agreement is reached. If both Mexico and OPEC abide by the agreement, then OPEC's profit will be $200 million and Mexico's profit will be $100 million. If both Mexico and OPEC cheat on the agreement, then OPEC's profit will be $175 million and Mexico's profit will be $80 million. If only OPEC cheats, then OPEC's profit will be $185 million, and Mexico's profit will be $60 million. If only Mexico cheats, then Mexico's profit will be $110 million, and OPEC's profit will be $150 million. Which of the following statements is correct?
OPEC does not have dominant strategy.
The _______ accommodates a much broader range of observed behavior than traditional economic models, but has been criticized because virtually any bizarre behavior can be explained by assuming people have a sufficiently strong taste for it.
Present aim standard of rationality
According to the _______, if Carla has many of the characteristics of a stereotypical basketball player (for example, she is tall), then people will be more likely to assume she plays basketball.
Representative heuristic
The market for bagels contains two firms: BagelWorld (BW) and Bagels'R'Us (BRU). The owners of the two firms decide to fix the price of bagels. The table below shows how each firm's profit (in dollars) depends on whether they abide by the agreement or cheat on the agreement. Suppose the game above is repeated every day, and both firms adopt the following strategy: cooperate on the first day, then if the other firm cheats, cheat the next day, and if the other firm abides, abide the next day. This type of strategy is known as:
a tit-for-tat strategy.

If both Mexico and OPEC abide by the agreement, then OPEC's profit will be $200 million and Mexico's profit will be $100 million.

If only OPEC cheats, then OPEC's profit will be $185 million, and Mexico's profit will be $60 million. If only Mexico cheats, then Mexico's profit will be $110 million, and OPEC's profit will be $150 million. Suppose Mexico chooses first, and then OPEC, after seeing Mexico's choice, chooses second. Before Mexico chooses, OPEC tells Mexico that if Mexico cheats on the agreement, then OPEC will also cheat, and if Mexico abides by the agreement, then OPEC will also abide. This is an example of a ______, and the outcome is that ______.
credible threat; neither will cheat
Joe is the owner of the 7-11 Mini Mart, Sam is the owner of the SuperAmerica Mini Mart, and together they are the only two gas stations in town. Currently, they both charge $3 per gallon, and each earns a profit of $1,000. If Joe cuts his price to $2.90 and Sam continues to charge $3, then Joe's profit will be $1,350, and Sam's profit will be $500. Similarly, if Sam cuts his price to $2.90 and Joe continues to charge $3, then Sam's profit will be $1,350, and Joe's profit will be $500. If Sam and Joe both cut their price to $2.90, then they will each earn a profit of $900. For Joe, keeping his price at $3 per gallon is a:
dominated strategy.
Generally, ______ motivates firms to enter an industry, while ______ motivates firms to exit an industry.
economic profit; economic loss
A cost-saving innovation in a perfectly competitive industry will lead to:
economic profits for a few firms for a short time.
According to the textbook, the most important and enduring source of market power is:
economies of sale.
Suppose Vincent is willing to pay $350 to buy a new bike. Loss aversion implies that if Vincent had just bought the bike, you would:
have to pay him more than $350 to part with it.
Suppose the accompanying figure illustrates the demand curve facing a monopolist. If the monopolist decreases its price from $12 to $10, its total revenue will ______.
increase by $600
Natasha is having difficulty deciding between two jobs, A and B. As shown in the accompanying diagram, A is closer to home than B, but doesn't pay as well. Ideally, Natasha would like a job that both pays well and is close to her home. If Natasha behaves like most decision-makers, then the addition of option C would:
increase her likelihood of picking B.
Corey is having difficulty deciding between two dishwashers, A and B. As shown in the accompanying diagram, A makes more noise than B, but is cheaper. Ideally, Corey would like a dishwasher that is both quiet and inexpensive. If Corey behaves like most decision-makers, then the addition of option C would:
increase his likelihood of picking A.
The accompanying figure shows the demand curve, marginal revenue curve, marginal cost curve and average total cost curve for a monopolist. At this monopolist's profit-maximizing level of output, it:
incurs an economic loss of $16 per day.
Miniville is an isolated town located on the southern shore of Lake Condescending, a very large lake. The western edge of Miniville is adjacent to impassable mountains and there are no towns or businesses for many miles to the east. The 300 residents of Miniville are evenly distributed along 3 miles of shoreline on the lake, east of the mountains. Lake Shore Drive, the only street in town, provides access to Miniville's homes and businesses. All residents live between the lake and the street; businesses locate on the other side of the street. Lake Shore Drive is 3 miles long, and the points labeled A, B, and C are 1, 2, and 3 miles from the western end of Lake Shore Drive, respectively. All residents of Miniville shop at the store located closest to their homes. If the first store to open in Miniville is located at A, to maximize the number of customers it attracts, the next store to open should locate:
just east of A.
Suppose there are two small island countries: Avarice, which is populated by people who are completely self-interested, and Altruism, which is populated by people who have adopted social norms of generosity and cooperation. Commitment problems will be:
largely avoided in Altruism, but prevalent in Avarice.
Suppose a perfectly competitive firm is producing 1,000 units of output and the marginal cost of the 1,000th unit is $7. If the firm can sell each unit of output for $7 and the firm's revenue is sufficient to cover its variable cost, the firm should:
leave production unchanged.
Suppose a firm uses workers and office space to produce output. The firm is locked into a year-long lease on its office space, but it can easily vary the number of employee-hours it uses each day. The accompanying table describes the relationship between the number of employee-hours the firm uses each day and the firm's daily output. Each unit of output sells for $2, the hourly wage rate is $14, and the rent on the office space is $50 per day. When the firm uses 9 employee-hours per day, it earns a daily ______ of ______.
profit; $64
Ingrid has been waiting for the show "Mamma Mia!" to come to town. When it finally does come, tickets cost $60. Ingrid's reservation price is $75. But when Ingrid tries to buy a ticket, they are sold out. Ingrid decides to try to buy a ticket from a scalper (a person who purchased extra tickets at the box office with the intent to resell them at a higher price). If Ingrid finds someone who is willing to sell her a ticket for $70, she should:
purchase the ticket because doing so will make her $5 better off.
The figure below depicts the short-run market equilibrium in a perfectly competitive market and the cost curves for a representative firm in that market. Assume that all firms in this market have identical cost curves. A starting assumption about this industry was that all of the firms in the market had identical cost curves. This assumption is:
realistic because any cost-saving innovation adopted by one firm will be quickly adopted by others.
Suppose the production of cotton causes substantial environmental damage because the pesticides used by cotton farmers often make their way into nearby rivers and streams, and are very harmful to fish and other wildlife. Economists would consider the environmental damage that results from the production of cotton to be a(n):
relevant cost of production.
The rule of thumb according to which people are more likely to assume something belongs to a given category if it shares many characteristics with the stereotypical members of that category is the:
representative heuristic.
