In an oligopoly market, collusion between firms usually leads to higher profits than noncooperative behavior. However, formal, overt collusion doesn't usually occur in the United States because: I. it is illegal. II. there is an incentive for each firm to cheat on a collusive agreement. III. an oligopolistic firm will typically prefer lower profits if the only way to make higher profits is to improve the profit position of its rivals.

The current equilibrium price per pack is $4, and every day 40 million packs of cigarettes are sold. In order to recover some of the health care costs associated with smoking, the government imposes a tax of $2 per pack. This will raise the equilibrium price to $5 per pack and reduce the equilibrium quantity to 30 million packs. The economist working for the tobacco lobby claims that this tax will reduce consumer surplus for smokers by $40 million per day, since 40 million packs now cost $1 more per pack. The economist working for the lobby for sufferers of secondhand smoke argues that this is an enormous overestimate and that the reduction in consumer surplus will be only $30 million per day, since after the imposition of the tax, only 30 million packs of cigarettes will be bought and each of these packs will now cost $1 more. They are both wrong. Why?
The economist working for the tobacco lobby is overestimating the change in consumer surplus and the economist working for the secondhand smoke lobby is underestimating the loss of consumer surplus.
In many European countries high minimum wages have led to high levels of unemployment and underemployment, and two a two-tier labor system. In the formal labor market, workers have good jobs that pay at least the minimum wage. In the informal, or black market for labor, workers have poor jobs and receive less than the minimum wage. Assume that the imposition of the high minimum wage causes a contraction in the economy so that employers in the formal sector cut their production and their demand for workers. Assume also that the workers who cannot get a job paying at least the minimum wage move into the informal labor market where there is no minimum wage. What happens to the size of the informal market for labor as a result of the economic contraction? What happens to the equilibrium wage in the informal labor market?
The equilibrium wage in the informal labor market falls and the quantity of hours transacted increases, as the informal labor market expands

In an auction, potential buyers compete for a good by submitting bids. Adam Galinsky, a social psychologist at Northwestern University, compared eBay auctions in which the same good was sold. He found that, on average, the higher the number of bidders, the higher the sales price. For example, in two auctions of identical iPods, the one with the higher number of bidders brought a higher selling price. According to Galinsky, this explains why smart sellers on eBay set absurdly low opening prices (the lowest price that the seller will accept), such as 1 cent for a new iPod. Using the concepts of consumer and producer surplus to explain Galinsky's reasoning, it is true that:
the low opening price means a potential buyer could have a larger share of the total surplus; this leads to more bids, and a higher final price
A consumer's willingness to pay reflects
the maximum price at which he or she would buy the good or service
The break-even price for a perfectly competitive firm is equal to:

Market structures are categorized by

Each student's willingness to pay for a movie ticket is $5. Each professor's willingness to pay for a movie ticket is $10. Each will buy at most one ticket. The movie theater's marginal cost per ticket is constant at $3, and there is no fixed cost. Suppose that, if it chooses to, the movie theater can price-discriminate between students and professors by requiring students to show their student ID. If the movie theater charges students $5 and professors $10, how much profit will the movie theater make? How large is consumer surplus?
