Public pensions and voting on immigration

In a recent paper, Scholten and Thum (1996) analyze the impact of a pay-as-you-go (PAYG) pension system with a fixed replacement ratio on the immigration policy in a democracy. We extend the analysis of median voters choice in two respects. First, in contrast to Scholten and Thum (1996) who assume myopic voting behavior, our paper considers fully rational agents and provides a solution under this more complex behavioral assumption. Voting with rational agents yields a more liberal immigration policy than with myopic voters. Second, we examine a different decision structure with a fixed contribution rate to the pension system. In this case the majority rule leads to a completely different solution.

Education Policy, Student Migration, and Brain Gain

In this paper, we analyse how increasing student migration from a less developed to a developed country alters education policy in the developed country, and how it affects human capital and welfare in the two countries. We argue that a higher permanent migration probability, i.e., a higher probability that international students continue to stay in their host country after graduation, incentivises the host country to improve its education quality. A higher education quality in turn raises the human capital of all students, including returning students. As long as the permanent migration probability is not too large, this positive quality effect increases human capital and welfare in both the less developed country (LDC) and the developed host country. Thus, a brain gain to the LDC occurs. A decline in the taxes on labour income in the two countries can reinforce this brain gain, although the developed country then raises the tuition fees.
