Abstract. We analyze the consequences of an increase in the supply of highly educated workers on relative and real wages in a search model where wages are set by Nash bargaining. A key insight is that an increase in the average education level exerts a negative externality on wages through its positive externality on the firms’ outside option. As a consequence, the real wage of all workers decreases in the short run. Since this decline is more pronounced for less educated workers, wage inequality increases. In the long‐run a better educated work force induces firms to invest more in physical capital. Wage inequality and real wages of highly educated workers increase while real wages of less educated workers may decrease. These results are consistent with the US experience in the 1970s and 1980s. Based upon differences in legal employment protection we also provide an explanation for the diverging evolution of real and relative wages in Continental Europe.  相似文献

Urbanized areas show a high proportion of non-native plants and can work as dispersal points to the surrounding areas. Ensenada is a fast growing city located in the northwestern peninsula of Baja California (Mexico). It is the southern extreme of a bi-national, coastal urban corridor that extends from Los Angeles, California south to Ensenada. This corridor is part of the biodiversity hotspot of the California Floristic Province. The aim of this study was to analyze the composition and distribution of the spontaneous flora in the city of Ensenada. We systematically sampled two differentiated urban environments, vacant lots and arroyos, in 2006 and 2007. We found a total of 158 plant species, 61% of them were non-native species. Arroyo areas showed higher non-native species richness than vacant lots (21.9 vs. 13.6 species/transect) and could be potential dispersal vectors for non-native species to natural areas outside of the city, or in the reverse direction also.  相似文献

On the grounds of borrowing and reforming Hirschman’s terminology, ‘exit, voice, loyalty’, we show both a conceptual and a methodological framework that can be used to raise questions in transitology studies. These issues include the following points: are there any models being developed concerning the transition countries?; are there any similar models in Western Europe?; is there any convergence between the models of both Eastern and Western Europe? If the answer to the last issue is yes, then in which areas? Or if it is a no, is it true that a special economic, social and also political system is developing in Eastern Europe? Another issue concerns how strong the growth potential of the different models is. It also examines which are the successful models and which are not, and what is the role of the economic and political elite in the development of these models. This study includes only the theoretical framework.  相似文献

Because of its recent and rapid growth, the Spanish development apparatus provides an appropriate arena for studying nongovernmental organizations (NGOs). This article uses case studies of three NGOs—Manos Unidas, Intermón Oxfam, and Madre Coraje—to explore the tension between the internal and external dynamics that affect these organizations. Although powerful external forces promote structural isomorphism with its attendant bureaucratization and professionalization, several internal factors—youth, small size, certain ideologies, charismatic leaders, and privileging identification with the organization rather than expertise when recruiting participants—resist these homogenizing processes. DiMaggio and Powell's iron cage hypothesis (1983) therefore can be only partially confirmed. We suggest an intriguing, intimate connection between charisma and democracy.  相似文献

The authors of this article describe a study of European companies the aim of which was to review the extent of multiple scenario analysis in company planning. They describe the differences in planning between users and non-users of the system, and analyse the benefits and drawbacks of using the system.  相似文献

The lack of vocational rehabilitation in Iceland inspired the Janus Rehabilitation initiative in the year 2000. The team currently consists of two occupational therapists, a social worker, a physiotherapist, a psychologist, and a physician. Janus uses resources from local education establishments and is located at the Reykjavík Technical School. A client-centred approach is used, enabling a flexible rehabilitation timeframe. The aim is to help the client back to employment/education. Advantage is taken of the facilities of the school where integration between education and rehabilitation takes place. Forty individuals have been admitted, with a mean time from work of 2.9 years, (range: 0-11 years). Seventeen (43%) have returned to employment/education. Twenty-three of those entering the programme are still on invalidity pension. The Canadian Occupational Performance Measurement (COPM) shows improvement in occupational performance and satisfaction. The Icelandic Quality of Life measurement also shows improvement. The results have been promising. However, a larger group is needed in order to draw clear unequivocal conclusions.  相似文献

This article describes research on fishermen's health and sleeping habits in Iceland. It presents the first findings of the project that were presented in October 2002 at a conference that was organized during Seamen Safety Week in Iceland. It covers physical and mental stress symptoms, sleep disturbance, and obesity, as well as fishermen's own reaction to their health and well-being. Take notice that the findings that are presented in this article can be found in a report presented in August, when the whole study will be finished. Finally, it is concluded how successful the response has been and how the project can be used positively with other studies. It is also noted that, in fact, these findings will be used for further studies linked to safety on board.  相似文献

Marriage and family therapy (MFT) training programs need to create opportunities for all students to develop cultural competency by raising their racial awareness and sensitivity. Likewise, therapists of color need to be offered space in MFT programs to voice their experiences and venues for their voices to be heard. This article reports on the efforts within a master's level, accredited MFT training program to create space, through participatory action research, for the unique experiences of therapists of color and White therapists who are deeply committed to racial sensitivity.  相似文献

Contextual variables, such as average education, gender composition, ethnicity and unionization, influence individual incomes differently when aggregated to occupations and to industries. Discriminatory effects exerted on income by ethnic and gender segregation in occupational labor markets are in some cases counterbalanced by segregation in industrial labor markets. Employment in different industries influences income irrespective of individual characteristics of the employees and irrespective of aggregate characteristics of their occupations. This impact of industrial location is also independent of organizational characteristics of the industries, even if the choice of characteristics is determined by the economic segmentation theory.  相似文献

In this paper, we introduce an extension of the generalized exponential (GE) distribution, making it more robust against possible influential observations. The new model is defined as the quotient between a GE random variable and a beta-distributed random variable with one unknown parameter. The resulting distribution is a distribution with greater kurtosis than the GE distribution. Probability properties of the distribution such as moments and asymmetry and kurtosis are studied. Likewise, statistical properties are investigated using the method of moments and the maximum likelihood approach. Two real data analyses are reported illustrating better performance of the new model over the GE model.  相似文献
