Low rates of internal migration in many European countries contribute to the persistence of significant regional labor market differences. I use the Mikrozensus, a large annual sample of households living in Germany, to further our understanding of the underlying reasons. This paper makes two main contributions: first, the paper quantifies the disutility of migrating. To this end, I estimate conditional logit models of the migration decision across the German federal states. Second, I then focus on the differences between immigrants and natives. I find significantly higher responsiveness to labor market differentials in the immigrant population than in the native population. Unobserved moving costs for immigrants are estimated to be only about 31 percent of this same cost for natives. The findings bear on the assessment of the economic impact of immigration, and the paper contributes to the current immigration‐related policy debates that feature prominently in many European countries, and that likely will continue to be important in light of the ongoing EU expansion and the resulting east–west migration.  相似文献

The Indigenous population in Canada totals approximately 1.6 million individuals, representing about 5% of the total population. The off-reserve Indigenous population represents the fastest growing segment of the Indigenous population, with over 50% living in urban settings. Despite the size of the off-reserve population, research on the health of Indigenous peoples tends to remain focused on reserve-based populations. The purpose of this paper is to contribute to a better understanding of health and social determinants of health among off-reserve Indigenous peoples in Canada. Using data from the 1991 and 2012 Aboriginal Peoples Surveys this paper examines changes in health status and the social determinants of health over a 20-year time span. Results show a decline in health care use and self-reported health status in the period between 1991 and 2012. The results may be related to urbanization, aging, and increased prevalence of some chronic conditions. The findings may also be tied to barriers to achieving adequate off-reserve health care—jurisdictional disputes, disjointed program coverage, systemic racism, and a lack of equity-oriented health services. There remains a pressing need for Indigenous and non-Indigenous governments, researchers, and policymakers to build new relationships that bridge these gaps in health and access to timely care.  相似文献

This contribution analyses the role of corporate regional responsibility (CRR) in cluster development, using the case of Volkswagen and its headquarter city Wolfsburg for illustration. The conceptual discussion of CRR and cluster development shows obvious synergies, as both the firm and the region benefit from the firm-led upgrading of the business environment. Recognising that their fate is mutually linked, Volkswagen started making strategic investment in its headquarter location in the late 1990s, based on a cluster concept. Despite apparent achievements in attracting suppliers and increasing the attractiveness and dynamism of the location, the company town’s dependence on its dominant firm remains obvious. Wolfsburg thus provides a showcase for the congruence of interests between firm and city as a precondition for successful CRR, but its transferability appears confined to company towns dominated by a single employer.  相似文献

The Ruhr area has advanced to the largest university region in Germany – often unnoticed within and outside. At the same time scientific institutions have become a major economic factor. Because of the higher and extra-university research institutions about 2.5 billion euros are effective as a demand potential in the region. 1.7 billion euros of this amount are directly associated with investments and operating expenditures of the scientific institutions as well as consumptions of employees and students. Additional 770 million euros result in revenues of many branches such as trade, housing, gastronomy sector, handcraft industry etc. It should not be underestimated that higher and extra-university research institutions generate with their research activities particular funding from the European Union or the rest of Germany for benefit of the region. Each euro spent by the state government for basic funding creates 39 cents third-party funding. These regional-economic effects result in noticeable employment impacts within the region. Around 25,000 people are directly employed in higher and extra-university research institutes or student unions (Studierendenwerke), about 22,000 jobs in other economic sectors are ensured or created by the induced demand. Science has thus become an important economic factor and represents an essential counterbalance to employment decline in shrinking industries of the region. The specific inclusion of science in a regional development strategy and targeted relining with appropriate measures to strengthen the science creates therefore an effective starting point for the design of structural change.  相似文献
