This article addresses whether low educated men are displaced from their jobs by higher educated workers in the Netherlands in the period 1980–2004. In particular, we test whether structural or cyclical crowding out is predominant in the Dutch labor market. In order to do so, we try to explain the observed trends in education-specific transition rates to entry into first employment from education, exit from employment into unemployment or inactivity, and re-entry into employment from unemployment or inactivity for men by both business cycle effects (that is, changes in aggregate unemployment rates) and structural effects (that is, changes in labor supply–demand ratios for high educated). Discrete-time event history models are estimated using the OSA Labor Supply Panel 1985–2004. Retrospective information enables to study trends from 1980 onwards, so that structural effects can be distinguished from cyclical effects. The results show that structural crowding out exists at both the worker in- and outflow. First of all, it was observed that a growth in the oversupply of high educated increases the employment exit risk of low educated workers more so than that of higher educated ones. In addition, it was shown that an increase in the oversupply of high educated especially reduces the re-employment chances of low educated unemployed men. There is no evidence found for cyclical crowding out among low educated workers in the Dutch labor market.  相似文献

We consider two apparently unrelated classes of combinatorial and geometric optimization problems. First, we give compact extended formulations, i.e., polynomial-size linear programming formulations with integer optima, for optimum path problems with turn restrictions satisfying a nested compatibility condition in acyclic digraphs. We then apply these results to optimum convex polygon problems in the plane, by interpreting certain dynamic programming algorithms as sequences of optimum turn-restricted path problems with nested compatibility in acyclic digraphs. As a result, we derive compact extended formulations for these geometric problems as well.  相似文献

This qualitative study utilizes critical ethnography methods to illustrate Palestinian refugee perceptions of higher education in Jordan. Participants addressed their assimilation to the Jordanian national identity as a means of obtaining education. Content and access to education were more important than assimilation, maintenance of ethnic identity, and a homogeneous national identity. The more immediate need for academic access and social or professional capital thwarted their desire to infuse their ethnic identity in academia.  相似文献

Effective mechanisms to exempt the indigent from user fees at health care facilities are rare in Africa. A State-led intervention (2004-2005) and two action research projects (2007-2010) were implemented in a health district in Burkina Faso to exempt the indigent from user fees. This article presents the results of the process evaluation of these three interventions. Individual and group interviews were organized with the key stakeholders (health staff, community members) to document the strengths and weaknesses of key components of the interventions (relevance and uptake of the intervention, worst-off selection and information, financial arrangements). Data was subjected to content analysis and thematic analysis. The results show that all three intervention processes can be improved. Community-based targeting was better accepted by the stakeholders than was the State-led intervention. The strengths of the community-based approach were in clearly defining the selection criteria, informing the waiver beneficiaries, using a participative process and using endogenous funding. A weakness was that using endogenous funding led to restrictive selection by the community. The community-based approach appears to be the most effective, but it needs to be improved and retested to generate more knowledge before scaling up.  相似文献

The Second Generation in Europe   总被引:1,自引:0,他引:1  
The study of integration processes has now reached a crucial stage in most Western European countries with the emergence of the second generation. The oldest children born to postwar immigrants on European soil have recently entered the job market, and we can now investigate their performance in both education and employment. This opens a unique opportunity to compare the situations of second generation migrants across countries. Ostensibly the children all have the same starting position, being born in the country of settlement. The intriguing question is how differences between immigrant groups, and also differences in national contexts, work to the benefit or detriment of the second generation. We discuss the first issue briefly, confining ourselves here to Turkish and Moroccan immigrants. In addressing the issue of national contexts, we focus primarily on policies and practices rather than on broad‐reaching national integration models. We examine in detail the integration process itself in the context of vital institutional arrangements such as the education system and the mechanisms for transition to the labor market. How do such arrangements differ between countries, and how do they affect the outcomes for the second generation?  相似文献
