8) Countries are debating the pros and cons of malaria eradication. The World Health Organization believes that with enough money malaria cases could be cut by 90 percent, but believes that it would be too expensive to eliminate the remaining 10 percent of cases. The organization concluded that countries should not stirve to eradicate malaria. Which one of the following arguments is true? A) The World Health Organization must think that for the last 10 percent of cases, the marginal benefit from eradication is less than its marginal cost. B) The World Health Organization must think that the marginal benefit of eradicting the last 10 percent of cases is negative. C) The World Health Organization must think that the allocatively efficient quantity of malaria eradication is less than 90 percent. D) The World Health Organization must think that for the last 10 percent of cases, the marginal benefit of eradication equals its marginal cost. E) The World Health Organization must think that 100 percent eradication is allocatively efficient.

Question 11 One potential remedy to the tragedy of the commons is to: never allow a single individual to consume more than one percent of the common resource. criminalize the usage of common resources. allow individuals to use a common resource as long as they receive some benefit from doing so. place a common resource under private ownership. 4 points Question 12 As a result of a positional externality: contestants have a tendency to invest in a series of mutually offsetting investments in performance enhancement. there is generally an underinvestment in performance enhancement. the market price of performance enhancement materials is too high. the quality of performance in competitive situations is lower than the socially optimal level. 4 points Question 13 Which of the following statements is true regarding health insurance? Economics shows that all health related procedures should be free to individuals because the health of an individual is priceless. Total economic surplus would be larger if individuals faced an incentive to only use services when the benefit exceeds their costs. Health maintenance organizations provide an incentive for doctors to prescribe expensive nonessential services. First dollar insurance coverage has likely had very little to do with rising healthcare expenditures since World War II. 4 points Question 14 A strategy that yields a higher payoff no matter what the other players in the game choose is known as a: prisoner's strategy. dominated strategy. dominant strategy. Nash strategy. 4 points Question 15 Based on the diagram below, if the costs of hospital care are constant at $200 per day, and the individual does not incur any cost for each day for hospital care, then: the individual will stay 7 days and there will be no loss in economic surplus. the individual will stay 3 days and there will be no loss in economic surplus. the individual will stay 7 days and there will be lost economic surplus. the individual will stay 3 days and there will be lost economic surplus. 4 points Question 16 Economic research by Manning and colleagues suggests that people with deductible health insurance policies: spend substantially less on health care and have substantially worse health outcomes compared to people with first-dollar insurance coverage. spend substantially more on health care and have substantially better health outcomes compared to people with first-dollar insurance coverage. spend basically the same amount on health care and have substantially worse health outcomes compared to people with first-dollar insurance coverage. spend substantially less on health care and have no measurable difference in health outcomes compared to people with first-dollar insurance coverage. 4 points Question 17 An efficient program for reducing pollution is one for which: all polluters incur the same total costs of abatement. all polluters pay the same amount in taxes to the government. all polluters have the same marginal costs of abatement. all polluters reduce their emissions by the same amount. 4 points Question 18 Given the information on pollution abatement costs of the two firms shown below, which of the following is an efficient combination of pollution reduction? Quantity of pollution abatement Firm A's MC of abatement Firm B's MC of abatement 1 $30 $25 2 $35 $30 3 $40 $35 4 $45 $40 Firm A reduces by 1 ton and Firm B reduces by 1 ton.

Firm A's abatement costs are constant at $20/ton, and Firm B's abatement costs are constant at $40/ton. The government's goal is to reduce pollution by half. If the government auctions 200 one ton permits to the highest bidder: Firm A will purchase all 200 permits.

Topic:
How would you explain the finding that people in high-income economies seem happier than people in low-income economies, but, over time, people in high-income economies do not seem to be any happier even if their country grows richer? Briefly discuss.

Optional Reading:

Income and Happiness

The Declaration of Independence in 1776 identified “certain unalienable Rights, that among these are Life, Liberty, and the Pursuit of Happiness.” This did not guarantee happiness but did establish the pursuit of happiness as an “unalienable” right, meaning that right cannot be taken away, given away, or sold. Eighteenth century philosopher and social reformer Jeremy Bentham argued that government policy should promote the greatest happiness for the greatest number of people.

Many people today apparently agree. In recent polls, 77 percent of Australians and 81 percent of Brits believed that a government's prime objective should be promoting the greatest happiness rather than the greatest wealth. The United Nations in 2007 sponsored an international conference on “Happiness and Public Policy.” Thailand now compiles a monthly Gross Domestic Happiness Index. Even China has joined in the fun reporting a happiness index based on polling results about living conditions, income, the environment, social welfare, and employment. Australia, Canada, and the United Kingdom are also developing happiness indexes.

Economists have long shied away from asking people how they feel, preferring instead to observe their behavior. But more now see some value in asking questions. In the most extensive of polls, the Gallup organization asked people in 130 countries: “How satisfied are you with your life, on a scale of zero to ten?” The results, reported in 2007, are not surprising. Most people in the high income areas, such as the United States, Europe, and Japan, said they are happy. Most people in the poor areas, especially in Africa, said they are not. Also, within a given country, income and happiness are positively related. After evaluating all the results of the Gallup world poll, Angus Deaton of Princeton concluded: “The very strong international relationship between per capita GDP and life satisfaction suggests that, on average, people have a good idea of how income, or the lack of it, affects their lives.” 8

So these results are no surprise. What does puzzle economists is that other surveys suggest that in affluent countries people do not seem any happier over time even though each generation became richer than the last. For example, in the United States, the proportion of people who say they are happy has stayed about the same despite 60 years of economic growth. In Japan, happiness responses actually declined despite a substantial increase in real income over the last 50 years.

Here are two possible explanations. First, people begin taking for granted those luxuries they most desired. For example, two generations ago color TVs, automobiles, and major appliances were luxuries, but now they are must-items for most households. Computers and flat screen HDTVs will soon move from luxuries to necessities. As each generation attains a higher standard of living, people become less sensitive to the benefits, they take them for granted, and thus they say they are no happier.

Second, research suggests that what matters is not just the absolute level of income but income relative other people in the reference group. Imagine you have a choice between (1) earning $50,000 a year while others in your reference group make $25,000 or (2) earning $100,000 a year while others make $250,000 (suppose, too, that prices remain the same, so $100,000 is double the real income of $50,000). Which would you prefer? Studies show that when people face this hypothetical choice, most pick the $50,000 option. That is, they prefer to make more than others even if that means a lower real income. Thus, if all incomes rise on average over time, this does not affect that aspect of happiness linked to one’s relative standing. As the social critic H. L. Mencken long ago observed, "A wealthy man is one who earns $100 a year more than his wife's sister's husband."
