Tobacco companies have often argued that they advertise to attract more existing smokers and not to persuade more people to smoke. Suppose there were just two cigarette manufacturers, Jones and Smith. Each can either advertise or not advertise. If neither advertises, they each capture 50 percent of the market and each earns $10 million. If they both advertise, they again split the market evenly, but each spends $2million on ads and so each earns just $8million (remember, advertising is not supposed to encourage more people to smoke). If one company advertises but the other does not, then the company that advertises attracts many of its rival's customers. As a result, the company that advertises earns $12 million and the company that does not earns just $6 million. What is each firm's dominant strategy? Both firms' dominant strategy is to advertise. Smith's dominant strategy is to not advertise and Jones's dominant strategy is to advertise. Smith's dominant strategy is to advertise and Jones's dominant strategy is to not advertise. Both firms' dominant strategy is to not advertise.
Both firms' dominant strategy is to advertise.

Scenario: Two firms in a market sell identical goods and charge a price of $5 per unit. However, the cost of a crucial input used in producing these goods has increased. As a result, both of the firms are considering increasing the price of the good to $6. If the firms do not raise their prices at the same time, the firm that raises the price stands to lose market share.

The new governor of Vermont is worried about increasing geographic inequality within the state. The richest county in Vermont, Chittenden, has median per capita income of about $32,000, while the poorest counties, Caledonia, Franklin, Orleans and Essex, have median income per capita around $20,000. Vermont has a budget of about $5 billion. The governor is considering changing the allocation of the budget and taxes in order to deal with the inequality problem. His advisors inform the governor that the increased budget shortfall would be costly to finance. He instead proposes to tax the residents of Chittenden. There are about 62,500 households in Chittenden. The governor proposes a tax of 12.5 percent on each household to finance his transfer program. His advisors explain to him that the tax revenue generated by this proposal will be less than the necessary amount. Why? - Taxing all residents of Chittenden on their $32,000 median income at 12.5% will result in only $40 million in additional income. - The higher tax will lead to lower labor supply, and thus household income will fall below $32,000 in Chittenden and there will be less tax revenue. - Taxing all residents of Chittenden on their $32,000 median income at 12.5% will result in only $4 million in additional income. - None of the above is correct.
The higher tax will lead to lower labor supply, and thus household income will fall below $32,000 in Chittenden and there will be less tax revenue.

Two gas stations, A and B, are locked in a price war. Each player has the option of raising its price (R) or continuing to charge the low price (C). They will choose strategies simultaneously. If both choose C, they will both suffer a loss of $−10. If one chooses R and the other chooses C, (i) the one that chooses R loses many of its customers and earns $0, and (ii) the one that chooses C wins many new customers and earns $100. If they both choose R the price war ends and they each earn $50 Does either player have a dominant strategy? Explain . - The stations have a dominantstrategy, which is for Station A to pick C and Station B to pick R because this is a best response regardless of what the other station does. - The stations have a dominantstrategy, which is for Station A to pick R and Station B to pick C because this maximizes their joint payoff. - The stations have a dominantstrategy, which is to pick C because this is a best response regardless of what the other station does. - The stations do not have dominant strategies because what works best depends on what the other station does.

Many people have argued that an income tax should be "marriage neutral," that is, two people should pay the same total tax whether they are married or they are single. Suppose Amanda earns nothing, Ben earns $60,000, and Cathy and Dylan each earn $30,000. They are all single. Amanda pays no tax because she has no income. If they all live in a country that has a progressive income tax, which will be higher: the tax that Ben pays or the sum of the taxes Cathy and Dylan pay? The sum of the taxes Cathy and Dylan pay because two people always pay more thanone, regardless of income. The tax that Ben pays because high-income individuals pay higher income taxes. Since Cathy andDylan's income sums to $60,000, these individuals will likely pay the same amount as Ben. More information is required to determine who pays the higher tax

As this chapter explains, a monopoly is an industry structure where only one firm provides a good or service that has no close substitutes. This question explores the last part of this definition further. In 1947, the United States government charged the DuPont Company with a violation of the Sherman Act. The government argued that DuPont was monopolizing the cellophane market. At trial, the government showed that DuPont produced nearly 75 percent of all of the cellophane sold in the United States each year. Nonetheless, the U.S. Supreme Court ruled in favor of DuPont and dismissed the case. Which of the following is a likely argument used by DuPont to convince the Supreme Court that it did not violate the Sherman Act? - As a monopoly, DuPont was beneficial to the community since it hired many workers and paid high salaries. - Cellophane is a small part of consumers' consumption, so monopoly pricing has not caused any harm to consumers. - There are many close substitutes for cellophane such as aluminum foil and waxedpaper, so DuPont did not have significant market power. - Since DuPont only produced 75 percent of allcellophane, not 100 percent, it is a price-taker with no pricing power.

Sirius XM Satellite Radio and XM Satellite Radio were the only two satellite radio providers in the United States. The Department of Justice (DOJ) and the Federal Communications Commission (FCC) approved the merger of the two companies in 2008 even though Sirius-XM would then control 100 percent of the satellite radio market. Which of the following arguments do you think Sirius and XM used to convince the DOJ and the FCC to allow the merger to proceed? - There are many close substitutes for satelliteradio; therefore, Sirius-XM would not exercise market power. - By stopping themerger, it would have limited the amount of variety on the radio, thereby limiting free speech. - Compared to the price of acar, the satellite radio subscription was too small a part of the consumer budget to matter. - Satellite radio is most often used in cars and neither firm had any pricing power in the car market.
There are many close substitutes for satelliteradio; therefore, Sirius-XM would not exercise market power.

When there is no threat of entry, Bill charges the maximum monopoly price. Then Bill discovers that a second software firm run by Larry is thinking about entering the market.
