内蒙古牧区生态移民补偿机制的合理化研究

内蒙古生态移民不仅关系到解决日益突出的草畜矛盾,恢复草原生态系统,而且有可能从根本上改变牧民的生产和生活条件。生态移民机制良性运行将涉及到如何对生态移民的合理化补偿问题。现行补偿机制科学论证不充分,缺乏夯实的经济分析理论基础,特别是没有将非经济成本纳入成本与收益的分析之中,加之社会某些不公因素,阻碍了生态移民政策真正成为一项利国利民的系统工程。内蒙古牧区生态移民补偿机制的合理化、标准化,要求政府构建各利益主体之间的协调机制、科学完善移民补偿制度,缓解各社会利益群体矛盾,使生态移民成为能够取得实际效果的公共政策。     

Evaluating the H-1B visa program： Theoretical issues

The H-1 B visa program is popular and controversial at the same time. It is supposed to serve U.S. interests by helping bring some of the most talented scientists and engineers （S＆E） to this country. There is considerable dispute, however, whether the program is successful in this regard, or whether employers misuse it to undercut the salaries of citizens and green card holders who apply for the same positions. This paper sorts out some of the theoretical issues that complicate empirical analyses and which, if ignored, could produce misleading results.     

Changes in recreation participation in natural environments after immigration among immigrants in the U.S., Netherlands,Germany and Poland1

This study examines the use of natural environments for recreation among immigrants and factors that led to changes in their use of natural environments between home and host countries. The data were collected through individual interviews with 13 Latino and 13 Chinese immigrants in the U.S., 15 Ukrainian and 11 Vietnamese immigrants in Poland, 9 Moroccan immigrants in the Netherlands and 9 Turkish immigrants in Germany. The findings show that changes in the use of natural environments for recreation are related to different types of nature in home and host countries, access-related issues, quality of natural environments, work focus among immigrants, transportation problems, cultural differences, lack of knowledge of opportunities, life stage and ageing. Based on the findings, we develop a model that outlines different types of interaction with natural environments among immigrants following their settlement in the host countries.     

Revisiting the Relationship between Ethnic Diversity and Preferences for Redistribution: Reply

Here, we respond to the comments raised by Nekby and Pettersson‐Lidbom on our paper Dahlberg et al. (2012, Journal of Political Economy 120, 41–76). We argue that our estimates are internally valid, but we acknowledge that the external validity could have been discussed more thoroughly.     

移民对国际贸易的影响——国外文献综述

传统的国际贸易理论一般认为劳动力的流动对国际贸易是替代作用，但是以Gould和Rauch为代表的一些经济学家从信息不完美和合约履行等角度认为移民对国家贸易会产生促进作用，并作了大量的实证分析，从而丰富了国际贸易理论，本文对这些文献进行了总结和综述，并做出简要评论。     

Globalisation versus de-coupling: German emigration and the evolution of the Atlantic labour market 1870–1913

The decline of German emigration to the United States after 1895 was precipitate to a degree not matched by other “old immigration” sources. The paper considers possible reasons for this: the effect of land availability, relative growth rates of the US and German economies, and the impact of the so-called “new immigration” from southern and eastern Europe. It concludes that German immigration was unusually affected by competition from newer migrant sources, due to skill similarities and similar patterns of settlement. However, the more rapid growth of the German economy after 1895 and the movement of the land frontier into areas less suited to German agricultural skills also played a part. It shows that the skills possessed by migrants were an important factor in migrant earnings. The arrival in the US of large numbers of immigrants with similar skill endowments and lower reservation wages made emigration to the United States a less attractive option for potential German migrants after 1895.     

Age at immigration and educational attainment of young immigrants

This paper investigates up to what immigration age the educational attainment of young immigrants in the Netherlands is similar to the educational attainment of second-generation immigrants. The borderline immigration age appears to depend on gender and country of origin.     

Segregation,Social Polarization and Immigration in Athens during the 1990s: Theoretical Expectations and Contextual Difference

This article investigates trends in segregation, polarization and inequality in Athens during the 1990s, and focuses on what may seem a paradoxical coexistence of decreasing segregation with increasing social polarization and inequality. To explain this coexistence, the article examines the distinction between social polarization in specific contexts and the dominant assumptions about social polarization, which derive from the global city thesis, and the structure of the city's housing market, which prevented the substantial wave of immigration during the 1990s from intensifying segregation. Arguing for more context awareness, the article does not try to stress the specificity of the Athenian case, but, mainly, to reveal the context‐dependent character of the dominant assumptions about segregation and social polarization and, therefore, to show their limitations.
