Paul Peretz 《政策研究评论》1986,5(3):624-633
This paper investigates one of the perennial mysteries in the area of state and local finance, the provision of tax and other subsidies to business by federal, state and local governments in the face of solid evidence that such incentives do little to nothing to influence business location or job creation. The paper looks at the upsurge in such governmental aid in the last decade and considers whether this upsurge has occurred because such aid is more efficacious than it used to be or whether it has occurred for political reasons unrelated to its effectiveness. 相似文献

The United States today faces a loss of influence as a world power, a reduction in American independence as a policymaker, and a decline in the standard of living on which Americans have come to depend. History teaches that nations weaker and less productive than the United States can rise to become economic powerhouses and rapidly increase their standards of living. History also teaches that nations failing to recognize their fundamental problems will inevitably decline. American politicians must face what is abundantly clear: the United States is losing ground and must act quickly to reverse its course. This White Paper outlines what must be done. Information about the nation's current status must be analyzed and communicated. Incentives to improve the level of competence in government must be provided and maintained. The emphasis of government policy must be changed to reflect broad economic and technological interests as opposed to special interests. Savings must be encouraged and increased. Infrastructure must be improved Tax laws must be modified to help bring these changes about. Economic and technological issues must be elevated to the importance they require. American thinking must reflect the new realities: that the age of leadership through military power is over, that the requirements for success in the world of the 1990s and beyond require a sound and growing economy that is internationally competitive. The US can accomplish these goals only through foundation-shaking, comprehensive, fundamental changealong the lines we propose herein.This paper is the executive summary (with minor editing modifications) of a white paper that is available from Cornell University's Johnson Graduate School of Management. 相似文献

Chris Baerveldt 《Journal of Quantitative Criminology》1992,8(1):79-94
Earlier research on the relation between school features and petty crime suggests that schools can intentionally influence the crime rate of the pupils. These findings were the starting point for a Dutch study at secondary schools of the same type in Dutch towns. The study focused on effects on the delinquency of third-year low-stream pupils (aged 15–17). For the study a control theory was formulated, a conditional control theory, which, in contrast to Hirschi's social control theory, recognizes possible delinquent influences of the pupils' network. In the study a strong statistical relation between integration of pupils in school and petty crime was found. However, I found almost no influence of the studied school features on integration and petty crime. These results led to the question whether the real important feature of schools had been neglected in the study. This seems not to be the case. A multilevel analysis shows that it is unlikely that there is major impact of schools on the integration of pupils, on delinquency, or on the relationship between integration and delinquency. This can be the result of special aspects of the Dutch school system and of the neglect of theory in earlier research. 相似文献

Defining risk 总被引:6,自引:0,他引:6
Risk is the focal topic in the management of many activities and technologies. For that management to be successful, an explicit and accepted definition of the term risk is essential. Creation of that definition is a political act, expressing the definers' values regarding the relative importance of different possible adverse consequences for a particular decision. Those values, and with them the definition of risk, can change with changes in the decisionmaker, the technologies considered, or the decision problem. After a review of the sources of controversy in defining risk, a general framework is developed, showing how these value issues can be systematically addressed. As an example, the approach is applied to characterizing the risks of six competing energy technologies, the relative riskeness of which depends upon the particular definition used. 相似文献
