This article provides experimental estimates of the impact of a voucher for private care on labour force participation and use of private and public child care within the Nordic system of universal provision of public care. In a market that was providing high-quality, low-cost public child care, a voucher is nevertheless found to have a significant, positive effect for the use of private child care with zero effects on either use of public care or labour force participation. The use of private increased by five percentage points in the whole country and by five to seven percentage points in areas that suffer from excess demand for child care as a result of the introduction of the private child care voucher.  相似文献

"This paper is divided into four sections. Section I deals with theoretical issues behind labor migration in general with emphasis on 'brain drain'. Section II is concerned with an empirical analysis of third world professional immigration into the U.S. for the time period 1972-1987. Section III discusses policy implications to deal with [the] 'brain drain' problem."  相似文献

This paper contains three subjects. First, an extension of Mokken's nonparametric item response models from dichotomous items to items with two or more ordered answer categories is proposed. Second, a computer program to analyze multicategory item scores is presented. This program is called MSP. The analyses by means of MSP are based on the multicategory extension of Mokken's theory. Finally, an application of MSP to empirical multicategory test data is presented in order to illuminate its possibilities.  相似文献

With a combined career of over 60 years in oncology nursing, the authors reflect on the critical elements in the question, "How can we afford to die?" Three high-profile patient scenarios in three different decades promised to improve use of advance directives but did not. Recent societal events, including the debates about health care reform, have brought attention again to end-of-life issues and care. Quickly approaching a "perfect storm" of an aging population, an inefficient and costly illness-oriented health care system, and health care profession shortages, the United States will not be able to afford delivering futile interventions. Nurses, who are consistently seen as the most trusted professionals, must take action in strategies the authors present.  相似文献

This paper develops a simple spatial model of fundraising, in which charities select a target population to solicit donations. First, we show that in a competitive charity market without any intervention, the number of charities in the market and/or the overall net funds raised by charities may be suboptimal. Next, we analyze whether a social planner can prevent such shortcomings and show that a regulatory mechanism can be designed to achieve socially desirable outcomes. In contrast to the previous literature, our model does not necessarily produce monopoly as the optimal market structure. We show that if fixed costs associated with establishing charities are sufficiently low, then the optimal market structure is not a monopoly. Given the importance of the trade‐off between the volume and variety of charitable services, we argue that this result may be of particular interest to policy makers.  相似文献

This paper considers a reputation model of optimal taxation in which the public is unsure about the government type. A long-lived government can be trustworthy (meaning that it commits to its announced tax rate) or opportunistic (meaning that it retains the ability to change its tax rate after announcing it). Unlike in most prior studies, the committed strategy in this model is optimally chosen by the trustworthy type. We show that this change has significant consequences for the equilibrium dynamics. The optimal committed strategy is found to vary with the time preferences of the two government types, the initial reputation of the government, and the elasticity of household production. This formulation explains differences in policy responses across governments in the face of similar credibility problems.  相似文献
