Get started for freeVaccines don't provide immunity from disease for some people. But if most people get vaccinated against a disease, such as measles, then the population achieves "herd immunity," which means that there are so few cases of the disease that even people for whom vaccinations are ineffective are unlikely to contract the disease. An article in the Economist argued that "herd immunity is a classic public good." a. Do you agree with this statement? b. The same article argued that there is an incentive to "free ride' off the contributions of others" by not getting vaccinated. What does the author mean by "free ride"? If the author is correct, what will be the effect of this free riding? c. Given your answer to part (b), why do most people vaccinate their children against childhood diseases, and why do many adults get vaccinated against influenza?
William Easterly in The White Man's Burden shared the following account by New York University Professor Leonard Wantchekon of how Professor Wantchekon's village in Benin, Africa, managed the local fishing pond when he was growing up: To open the fishing season, elders performed ritual tests at Amlé, a lake fifteen kilometers from the village. If the fish were large enough, fishing was allowed for two or three days. If they were too small, all fishing was forbidden, and anyone who secretly fished the lake at this time was outcast, excluded from the formal and informal groups that formed the village's social structure. Those who committed this breach of trust were often shunned by the whole community; no one would speak to the offender, or even acknowledge his existence for a year or more. What economic problem were the village elders trying to prevent? Do you think their solution was effective?
In recent years, companies have used fracking, or hydraulic fracturing, in drilling for oil and natural gas that previously could not be profitably recovered. According to an article in the New York Times, "horizontal drilling has enabled engineers to inject millions of gallons of high-pressure water directly into layers of shale to create the fractures that release the gas. Chemicals added to the water dissolve minerals, kill bacteria that might plug up the well, and insert sand to prop open the fractures." Experts are divided about whether fracking results in significant pollution, but some people worry that chemicals used in fracking might lead to pollution of underground supplies of water used by households and farms. a. First, assume that fracking causes no significant pollution. Use a demand and supply graph to show the effect of fracking on the market for natural gas. b. Now assume that fracking does result in pollution. On your graph from part (a), show the effect of fracking. Be sure to carefully label all curves and all equilibrium points. c. In your graph in part (b), what has happened to the efficient level of output and the efficient price in the market for natural gas compared with the situation before fracking? Can you be certain that the efficient level of output and the efficient price have risen or fallen as a result of fracking? Briefly explain.
A column in the New York Times notes that many economists "support Pigovian taxes because, in some sense, we are already paying them." In what sense might consumers in a market be "paying" a Pigovian tax even if the government hasn't imposed an explicit tax?
What do economists mean by "an economically efficient level of pollution"?
