The terrorist attacks of September 11, 2001, provoked, among other reactions, considerable commentary about the future of American federalism, particularly predictions of administrative centralization. To assess the potential impact of terrorism on U.S. intergovernmental relations and the ways the federal system should respond, members of the American Political Science Association's Section on Federalism and Intergovernmental Relations were surveyed in late 2001. Generally, these federalism scholars believe the September 11 terrorism will have little effect on intergovernmental relations or on the U.S. Supreme Court's state–friendly jurisprudence, and the surge in public trust and confidence in the federal government will be short–lived. The scholars tend to support a highly federalized response to terrorism, but with intergovernmental cooperation. Partisan differences among the scholars on policy options, however, mirror the party differences in Congress and the resurgence of "politics as usual" less than a year after September 11, 2001.  相似文献

This research reports on a public-opinion survey on intergovernmentaland border issues in Canada and the United States conductedin mid-April 2002. In the United States, there was an upsurgein public support for the federal government in 2002 over 2001,and a slight decline in public evaluations of state and localgovernments. Increased support for the federal government wasespecially notable among whites, Republicans, and respondentswith post-undergraduate education-groups that previously registeredlow support for the federal government. Canadians reported lesssatisfaction with all governments in their federal system, lowersupport for their federal government, and much more regionaland partisan division over intergovernmental issues. On internationalborder issues, Americans and Canadians generally agreed thata common border-security policy would be a good idea, thoughCanadians were slightly more likely than Americans to preferease of cross-border trade over improved border security.  相似文献

A tax expenditure budget should contribute to efficient and effective public decisions by quantifying the division in the tax structure between provisions that represent revenue policy (distribute the cost of government according to the legislated tax base) and parts that represent budget policy (substitute for direct spending). For this transparency to have the desired impact, however, the tax expenditure budget process and the direct expenditure process must be properly integrated and the tax expenditure budget must make an accurate division between the parts of the tax structure. A review of the 33 states with tax expenditure systems shows many weaknesses in application of the concept and poor linkage to the direct spending budget system. Their most significant flaw is in dividing the tax structure into normal and preference elements; states need greater attention to defining their basic tax structure if they are to have a meaningful tax expenditure budget.  相似文献

We consider a rent-seeking contest of the kind introduced by Tullock (1980) in which two players compete for a monopoly rent. We extend the contest by requiring that if a player puts forward an effort, his expenditures must be larger than or equal to some minimum level. We show that, depending on the model parameters, the number of Nash equilibria of the extended model can be zero, one, two or four. Furthermore, it turns out that the extent of rent dissipation in a Nash equilibrium of the extended model can be larger than, equal to, or smaller than the extent of rent dissipation in the unique Nash equilibrium of the original model.  相似文献

In “Reconciling voters' behavior with legislative term limits,” Dick and Lott argue that since more senior representatives are better at rent-seeking, there is an inefficient tendency to re-elect incumbents. In their model, term limits are preferred collectively by constituencies, even though no constituency would independently oust its incumbent representative. However, many term limits are unilaterally self-imposed (in particular the 22nd amendment limiting presidents' terms to two), and their model cannot explain these limits. In this comment, I suggest that term limits may be self-imposed by risk-averse voters, who prefer cycling between left and right wing candidates to a once-and-for-all election that imposes a candidate of a single ideology on the entre electorate. The market failure that makes term limits helpful is that out of power minorities cannot bribe the median voter.  相似文献
