7、 Measles Epidemic of 19891991A P P L I C A T I O N After the measles vaccine was introduced in 1963, measles cases had become relatively rare in the U.S. by the 1980s. Over the period from 1989 to 1991, however, there was a huge resurgence in measles. It is clear that this outbreak resulted from ver

8、y low immunization rates among disadvantaged inner-city youths. These unimmunized children were imposing a negative externality on other children who had received their immunizations but for whom immunization may have worn off. The federal government responded to this health crisis in the early 1990

9、s:The government publicly encouraged parents to get their children immunized. The government also paid for the vaccines for low-income families.The result was impressive. Immunization rates, which had never been above 70% before the epidemic, rose to 90% by 1995. Government intervention clearly redu

Through taxes, which raise the price for private sales or purchases of goods that are overproduced, or2. Through subsidies, which lower the price for private sales or purch

18、sional Budget Office: Government ScorekeepersA P P L I C A T I O N The methods and results derived from empirical economicsare central to the development of public policy at all levelsof government. The Congressional Budget Office (CBO) provides Congress with the objective, timely, nonpartisan analy

19、ses needed for economic and budget decisions. The CBO increasingly plays a critical role as a “scorekeeper” for government policy debates. Legislative spending proposals that are to become law must first have their costs estimated by the analysts at the CBO.It is not an overstatement to say that the

20、 economists who work at the CBO frequently hold the fate of a legislative proposal in their hands. The large price tag that the CBO assigned to the Clinton administrations plan to reform health care in the United States in 1994 is often cited as a key factor in the defeat of that proposal.

The Occupati

The financing structure of this program is basically that todays young workers pay the retirement benefits of todays old.Health CareThere are currently 45.8 million

39、Americans without any health insurance, about 18% of the non-elderly U.S. population. Projections suggest that health care will consume almost half of our GDP within the next century.Social Security, health care, and education are each the subject of debate, with both the “liberal” and “conservative

40、” positions holding differing views in their approach to each problem.Chapter 1 Why Study Public Finance? 2007 Worth Publishers Public Finance and Public Policy, 2/e, Jonathan Gruber27 of 28Education1 . 3Why Study Public Finance Now?

42、m the facts presented here that the government plays a central role in the lives of all Americans. It is also clear that there is ongoing disagreement about whether that role should expand, stay the same, or contract.The facts and arguments raised in this chapter provide a backdrop for thinking about the set of public finance issues that we explore in the remainder of this book.
