marginal revenue.
Economic theory assumes that a firm's goal is to: earn an accounting profit. earn an economic profit. maximize its accounting profit. maximize its economic profit.
maximize it's economic profit

The accompanying table shows a pizzeria's fixed cost and variable cost at different levels of output. Pizzas sell for $20 each. When the pizzeria makes 125 pizzas per day, its total revenue is _____. $2,500 $1,250 $125 $20
$2,500 Total revenue equals price × quantity, which in this case is $2,500 = $20 × 125.

Refer to the figure below. If a price ceiling were imposed at $4, total economic surplus would be ______, which is ______ less than when the market is unregulated market. $8; $24 $24; $8 $24; $16 $48; $8
$24; $8 Explanation: If this market were unregulated, total economic surplus would be $32. With the price ceiling of $4, consumer surplus would be $20, and producer surplus would be $4, so total economic surplus would be $24, which is $8 less than when the market is unregulated.

John is trying to decide how to divide his time between his job as a stocker in the local grocery store, which pays $7 per hour for as many hours as he chooses to work, and cleaning windows for the businesses downtown. He makes $2 for every window he cleans. John is indifferent between the two tasks, and the number of windows he can clean depends on how many hours he spends cleaning in a day, as shown in the accompanying table.

A consumer goes to purchase a TV advertised for $300. As he is checking out, the clerk informs him of a $20 rebate offer for the TV, which he fills out and receives in 3 months. What can one can infer about the consumer's reservation price? It was at least $300. It was at most $280. It was exactly $300. It was at least $280 but less than $300.
It was at least $300.
Curly told Larry about his new business venture: Curly pays Acme International $1,000 per month for supplies, works out of his apartment on his own computer and earns a monthly revenue of $1,500. Should Larry quit his job and do what Curly is doing? -Yes, as long as Larry has at least $1,000 in savings to get started. -Not if Larry is earning more than $500 per month at his current job. -Not unless Larry can borrow the $1,000 monthly payment at no interest. -Yes, as long as Larry can work out if his apartment and owns a computer.
Not if Larry is earning more than $500 per month at his current job. If Larry is earning more than $500 per month at his current job, then if he did what Curly was doing, his economic profit would be negative.

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. In the Nash equilibrium of this game: -both Mexico and OPEC abide by the agreement. -both Mexico and OPEC cheat on the agreement. -Mexico cheats on the agreement and OPEC abides by the agreement. -OPEC cheats on the agreement and Mexico abides by the agreement.

Suppose that you have noticed that almost all of the car dealers in your city are located along a three-block stretch of the same street. A likely reason for this clustering of car dealers is that: -the dealers are better able to form a cartel. -each dealer is attempting to locate closest to the customers. -there is a social norm in that city that dealers follow in choosing location. -each dealer sells a different brand of car, so they are not competitors and do not have to be concerned about the other dealers' locations.

If the marginal cost of producing one is lower than the marginal cost of producing the other, and the monopolist charges a different price for the two goods, then the monopolist is: -not price discriminating. -imperfectly price discriminating. -perfectly price discriminating. -not maximizing its profit.
not price discriminating.
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 ______. -loss; $64 -profit; $64 -loss; $114 -profit; $114

John is trying to decide how to divide his time between his job as a stocker in the local grocery store, which pays $7 per hour for as many hours as he chooses to work, and cleaning windows for the businesses downtown. He makes $2 for every window he cleans. John is indifferent between the two tasks, and the number of windows he can clean depends on how many hours he spends cleaning in a day, as shown in the accompanying table.

The payoffs to each of developing a touch-screen t-shirt depend upon the actions of the other, as shown in the payoff matrix below (the payoffs are given in millions of dollars).

Suppose Jordan and Lee are trying to decide what to do on a Friday. Jordan would prefer to see a comedy while Lee would prefer to see a documentary. One documentary and one comedy are showing at the local cinema. The payoffs they receive from seeing the films either together or separately are shown in the payoff matrix below. Both Jordan and Lee know the information contained in the payoff matrix. They purchase their tickets simultaneously, ignorant of the other's choice. Suppose a timing element is added to the game, and that Jordan buys a ticket first. Then, after seeing Jordon's choice, Lee buys a ticket. What will be the equilibrium outcome? -Both Jordan and Lee will buy a ticket to the comedy. -Both Jordan and Lee will buy a ticket to the documentary -Jordan will buy a ticket to the comedy and Lee will buy a ticket to the documentary. -Jordan will buy a ticket to the documentary and Lee will buy a ticket to the comedy.

Before it became illegal, cigarette manufacturers once relied heavily on TV advertising. According to the textbook, when the government banned TV advertising, the cigarette manufacturers: -supported the ban due to their concern over health effects of smoking. -thought their First Amendment rights were being violated. -were made worse off because the ban significantly reduced cigarette sales. -benefited because the decision about whether to advertise on TV was a prisoner's dilemma.
benefited because the decision about whether to advertise on TV was a prisoner's dilemma.
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. Suppose Steven was able to purchase a ticket at the box office for $60. Steven's reservation price for the ticket is $65. If Steven attends "Mamma Mia!" and Ingrid does not, then this situation is: -inefficient because Steven and Ingrid could have made a mutually beneficial trade. -efficient because Steven paid less for the ticket than his reservation price. -efficient because Steven arrived at the ticket counter before the show was sold out. -inefficient because Ingrid would have enjoyed the show too.
inefficient because Steven and Ingrid could have made a mutually beneficial trade.
The No-Cash-on-the-Table Principle states that there are: -never unexploited opportunities available to individuals. -never unexploited opportunities available to individuals in equilibrium. -sometimes unexploited opportunities available to individuals in equilibrium. -always unexploited opportunities available to individuals.
never unexploited opportunities available to individuals in equilibrium.
Game theory is not useful in understanding perfect competition because in a perfectly competitive market: -no single firm can influence the market price, so firms' decisions are not interdependent. -each firm only cares about its own profit, so there is no interdependence. -there are too many firms to be able to model their behavior accurately using game theory. -the payoffs to firms' choices are unknown.
no single firm can influence the market price, so firms' decisions are not interdependent
