Evidence is found that state-level economic conditions played a significant role in the defeat of George Bush in the 1992 U.S. presidential election. Evidence is also found which indicates that the entrance of Ross Perot into the race as an independent candidate was not instrumental in the Bush loss.  相似文献

Numerous laboratory experiments have investigated the performance of several processes for providing public goods through voluntary contributions. This research has been able to identify features of the institution or environment which are reliably likely to produce outcomes “close” to the free riding outcome or “substantially” greater than the pessimistic prediction of standard models. One such feature is the “marginal per-capita return” (MPCR) from the public good. Various authors have altered MPCR between groups or for an entire group at the same time. The experiments reported here address a different question, “What would happen if, within a group, some persons faced a ‘high’ MPCR while others faced a ‘low’ MPCR?”  相似文献

Several conclusions may be drawn from the information we have presented here. First and without doubt, the University of Chicago is by far the most dominant force overall, and is particularly so with respect to the production of pages and papers published in the Journal of Law and Economics. The George Mason-Virginia Tech influence is strong with respect to Public Choice, but is not, in our opinion, dominant.One does not necessarily need to be located at a large, research-oriented school in order to publish in either journal, but these schools are the source of most contributions. This is particularly true of the JLE but significantly less so for PC. The source of contributions is very broad, but top 50 institutions account for the lion's share. Contributions by persons employed at foreign institutions are important, particularly for PC.  相似文献

We examine whether nations, faced with the threat of terrorism, will be motivated to engage in the efficient amount of retaliation against terrorists. We demonstrate that the problem confronting the efforts of nations to achieve an optimal retaliation against terrorists is understated by the traditional free-rider analysis. In particular, nations have the option of actually selling or reducing the public good of retaliation, provided through the efforts of others, by offering safe havens to terrorists in return for the terrorists' pledge to attack elsewhere. This paid-rider behavior is also shown to apply to other public good scenarios.The authors gratefully acknowledge the helpful comments of Gordon Tullock on an earlier draft. Sole responsibility for the paper's content rests with the authors. Todd Sandler's research was supported by a Science and Humanities Research Institute Summer Grant at Iowa State University.  相似文献

In Study 1, 605 adolescents estimated how well their parents knew them and said how much they cared what their parents thought about them. Sons and daughters judged that mothers knew them fairly well, but daughters judged that fathers did not know them so well. At the same time, statements of caring indicated high concern by sons and daughters for both parents. A supplemental result was that sons from white-collar families gave relatively low estimates of how much their mothers knew them and daughters from blue-collar families gave very low estimates of how much their fathers knew them. In Study 2, 52 adolescents from single-parent families and living with their mothers but not with their fathers also gave estimates for knowing and caring. Knowing followed the above pattern, with an expected lowering of estimates for fathers by sons and daughters. Further, estimates of caring declined especially for fathers by daughters. These results add to the growing literature that shows mother-adolescent and father-adolescent relationships contribute differentially to psychological development. The results seem especially relevant for adolescents' sex role development and constructed individuality as mediated through relationships with both parents.Received Ph.D. in experimental psychology from The Catholic University of America.

Under the Burger Court, the constitutional relationship betweenstates and their municipalities has been examined primarilyin cases involving private suits initiated against municipalitiesunder federal antitrust and civil rights statutes. Since theCourt's 1943 Parker v. Brown decision, it had been presumedthat municipalities as political subdivisions of states wereas immune as their states from tort liability under the ShermanAntitrust Act. The Burger Court, however, ruled that municipalitiesare not automatically immunized from tort liability simply becauseof their status as political subdivisions unless they can demonstratethat their actions were undertaken pursuant to an expressedstate policy. After 1980, the Court continued to uphold thevulnerability of municipalities to private suits authorizedby federal statutes, but moved to narrow the types of remedyappropriate under common law. The Burger Court did not, therefore,address the more fundamental question of whether municipalitiesas public actors should be liable to private damages in thecourse of their public functions.  相似文献
