The present paper analyses the political economy of accounting regulation. It develops a game theoretic model of earnings management in a capital market context. Various forms of information asymmetry are examined. The analysis shows that the preferences of managers over the strictness of accounting regulation depend on the nature of the information asymmetry. In a number of instances, managers prefer to be subject to strict regulation. This result contradicts the often heard assertion that managers prefer lax regulation and has implications for regulatory competition. 相似文献

Two-phase case–control studies cope with the problem of confounding by obtaining required additional information for a subset (phase 2) of all individuals (phase 1). Nowadays, studies with rich phase 1 data are available where only few unmeasured confounders need to be obtained in phase 2. The extended conditional maximum likelihood (ECML) approach in two-phase logistic regression is a novel method to analyse such data. Alternatively, two-phase case–control studies can be analysed by multiple imputation (MI), where phase 2 information for individuals included in phase 1 is treated as missing. We conducted a simulation of two-phase studies, where we compared the performance of ECML and MI in typical scenarios with rich phase 1. Regarding exposure effect, MI was less biased and more precise than ECML. Furthermore, ECML was sensitive against misspecification of the participation model. We therefore recommend MI to analyse two-phase case–control studies in situations with rich phase 1 data. 相似文献

Community organization graduates of the School of Social Work, University of Washington, from 1966 to 1971, found a ready market for their skills although there was evidence of some slackening of demand and broader diversification of initial employment settings in the last two years. Graduates moved rapidly into administrative and management levels and appeared relatively stable in terms of interagency and geographical mobility. The small number of ethnically identified graduates made meaningful comparisons difficult. Sex, however, was a disadvantaging factor in employability and subsequent status. Of the ninety-one graduates surveyed, 94.5 percent responded Similar follow-up study of graduates in other geographic regions was recommended 相似文献

State standards for domestic violence perpetrator treatment: current status, trends, and recommendations 总被引:1,自引:0,他引:1
We empirically surveyed and analyzed existing standards for the treatment of perpetrators of domestic violence across the United States. Specific areas examined included: presence and scope; administrative entity for certifying; screening and risk assessment protocols; minimum length of treatment; theoretical or conceptual orientation; treatment content; preferred or allowable modalities of treatment; whether research findings are mentioned; methods for revising standards; and minimum education and training required for providers. We examined trends using several methods including comparisons between present and previous survey data (Maiuro et al., 2001). Positive trends were evident including increased use of multivariate models of treatment content, use of an intake assessment prior to treatment, use of a danger/lethality assessment to manage risk, recognition of the need for program evaluation and supportive research, and the requirement of a minimum level of formal education as a prerequisite for providers. We identify specific areas for further research and development and make recommendations for improving existing practice and standards of care. 相似文献

The situation in Iraq remains unstable. This is, among other factors, due to the lack of a realistic, long-term and integrative model for democratization. The current occupying powers neither dispose of a long-term plan, appropriate to the local circumstances, which could be able to include systematically local culture and social forms. Nor do they obviously have a clear step-by-step plan within the framework of an integral model which could take into account the experience of the past decades regarding sustainable democratization of Islamic core areas. This essay presents the three currently most promising and most realistic models of how Iraq can be democratized by means of a long-term, comprehensive, holistic and systematically differentiated strategy. The focus of attention is on the methodical inclusion of cultural, socio-psychological and sociological aspects. The three democratization models for Iraq are: 1) the Tatarstan model, 2) the Turkey model, 3) the model of stratified democracy. These three models are critically discussed and evaluated; in conclusion a short outlook will be drafted. 相似文献

Inherent in the decision to launch the Global Polio Eradication Initiative in 1988 was the expectation for many people that immunization against poliomyelitis would eventually simply stop, as had been the case with smallpox following its eradication in 1977. However, the strategies for managing the risks associated with a "polio-free" world must be continuously refined to reflect new developments, particularly in our understanding of the live polioviruses in the oral poliovirus vaccine (OPV) and in the international approach to managing potential biohazards. The most important of these developments has been the confirmation in 2000 that vaccine-derived polioviruses (VDPVs) can circulate and cause polio outbreaks, making the use of OPV after interruption of wild poliovirus transmission incompatible with a polio-free world. A comprehensive strategy has been developed to minimize the risks associated with eventual OPV cessation, centered on appropriate long-term biocontainment of poliovirus stocks (whether for vaccine production, diagnosis, or research), the controlled reintroduction of any live poliovirus vaccine (i.e., from an OPV stockpile), and appropriate use of the inactivated poliovirus vaccine (IPV). Although some aspects of this risk management strategy are still debated, there is wide agreement that no strategy would entirely eliminate the potential risks to a polio-free world. The current strategy for risk management in a polio-free world will continue to evolve with better characterization of these risks and the development of more effective approaches both to reduce those risks and to limit their consequences should they occur. 相似文献

We exploit Bayesian criteria for designing M/M/c//r queueing systems with spares. For illustration of our approach we use a real problem from aeronautic maintenance, where the numbers of repair crews and spare planes must be sufficiently large to meet the necessary operational capacity. Bayesian guarantees for this to happen can be given using predictive or posterior distributions. 相似文献

Our study focuses on the differences in wages and employment between French workers with French parents and French workers with at least one African parent, using the Formation Qualification Professionnelle survey (Insee, Paris, 2003). We introduce econometric decompositions, which allow us to reach conclusions when the potentially discriminated group is small. Then, we clarify the impact of discrimination at the hiring level in this context. We find that unexplained parts in the employment decompositions are much larger than in the wage decompositions. This suggests that, in France, labor market discrimination is more frequent at the hiring level than in the compensation process. 相似文献
