We examine the relative importance of tax rates and macroeconomic fluctuations in explaining the share of national adjusted gross income (AGI) reported by the top 0.5% of all taxpayers. Results indicate that cutting the top income or capital gains tax rate would increase the top AGI share but not by enough to increase revenues. The preponderance of evidence suggests that the top AGI share is affected more by the capital gains tax rate than by the income tax rate but that real gross domestic product fluctuations have even larger effects. 相似文献

The success of the Global Polio Eradication Initiative promises to bring large benefits, including sustained improvements in quality of life (i.e., cases of paralytic disease and deaths avoided) and costs saved from cessation of vaccination. Obtaining and maintaining these benefits requires that policymakers manage the transition from the current massive use of oral poliovirus vaccine (OPV) to a world without OPV and free of the risks of potential future reintroductions of live polioviruses. This article describes the analytical journey that began in 2001 with a retrospective case study on polio risk management and led to development of dynamic integrated risk, economic, and decision analysis tools to inform global policies for managing the risks of polio. This analytical journey has provided several key insights and lessons learned that will be useful to future analysts involved in similar complex decision-making processes. 相似文献

During the 1980s, many school-based primary prevention programmes were developed and adopted by schools. Much of the early enthusiasm which greeted these programmes dissipated in the light of often disappointing evaluations of the impact of the programmes on children. It is argued, however, that evaluating student outcomes should not occur before theextent of programme utilization is established. In this paper, an overview is given on the dilemmas and problems faced by teachers attempting to implement a primary prevention programme in South Australia. It is revealed that teachers selectively omit sections of the primary prevention programme as a way of resolving personal dilemmas presented by the programme. Some teachers are sensitive about teaching personal and controversial issues related to child abuse, while others deny the seriousness of child abuse in theirschool. The implications of the findings are that: (a) it cannot be assumed that primary prevention programmes are implemented by teachers in ways that are consistent with programme design; (b) teachers' personal beliefs, attitudes and feelings need to be addressed in any school-based primary prevention initiative; (c) training approaches and school support mechanisms need to focus on methods by which teachers can resolve the dilemmas raised by school-based primary prevention programmes in ways other than by radically dismembering the programme. 相似文献

Social workers seeking licensure in most states must pass one of the four different written examinations developed by the American Association of State Social Work Boards (AASSWB). These examinations are claimed to be valid measures of professional social work knowledge and competence to practice. To test this claim, we administered the multiple-choice 50-item Advanced practice examination contained within the official AASSWB Advanced study guide to 42 first year MSW students. Weblanked out the actual question content, and asked the students to select the correct answers from among the four choices given. Chance would suggest that the average score should be about 25% correct (one out of four). In actualitythe students' scores averaged 37% correct, a statistically significant difference. These results challenge the content and discriminant validity of the AASSWB examination and call for further studies on the examinations' value. 相似文献

This research investigates the distinctions between bankrupt firms and equally leveraged firms that avoid bankruptcy. Building upon the systemic incentives of bankruptcy law, and specifically those applicable to Chapter 11 reorganizations, the study argues that the firm’s governance and capital structure characteristics moderate the relationship between the firm’s financial condition and the filing decision. The results of this study indicate that, contrary to agency theoretical predictions, firms with high levels of inside equity ownership and secured indebtedness file in poorer financial condition than peer firms with low levels of these variables. By contrast, firms with high levels of outside equity ownership and short-term indebtedness file when in relatively better financial condition. 相似文献
