Demographic change will be one of the most challenging issues for industrialized economies in the decades to come. In this paper, we focus on the impact of demographic change on labour markets. By setting up a stylized model of a regional labour market, we are able to analyze the interaction of...

There is much evidence against the so-called "too big to fail" hypothesis in the case of bailouts to sub-national governments. We look at a model where districts of different size provide local public goods with positive spillovers. Matching grants of a central government can induce...

Various authors, most notably Putnam (2000), have argued that low-density living reduces social capital and thus social interaction, and this argument has been used to buttress criticisms of urban sprawl. If low densities in fact reduce social interaction, then an externality arises, validating...

In this note, we show that labour market integration can be a double-edged sword. In the presence of local human capital externalities, integration and the ensuing agglomeration of skilled labour can cause a decline in human capital and the total wage sum (net of education costs). In particular,...

The purpose of this paper is to critically review the past four decades of empirical research on the relationship between internal migration and regional variation in the generosity of Canada's unemployment insurance system. It has long been argued that because the Canadian insurance system is...

This work focuses on a temporary guest-worker-type migration of individuals from the middle class of the wealth distribution. The article demonstrates that the possibility of a low-skilled guest-worker employment in a higher wage foreign country lowers the relative attractiveness of the skilled...

It is widely debated whether immigrants who live among co-ethnics are less willing to integrate into the host society. Exploiting the quasi-experimental guest worker placement across German regions during the 1960/70s as well as information on immigrants' inter-ethnic contact networks and social...

We develop a general model of legal and illegal immigration to understand the basic tradeoffs faced by a government in the decision to implement an immigration amnesty in the presence of a selective immigration policy. We show that two channels play an important role: an amnesty is more likely...

Why are better educated and more risk-friendly persons more mobile across regions? To answer this question, we use micro data on internal migrants from the German Socio-Economic Panel (SOEP) 2000-2006 and merge this information with a unique proxy for region-pair-specific cultural distances...

Immigration control-related audits and their resulting sanctions are not solely determined by impartial enforcement of laws and regulations. They are also determined by the incentives faced by vote-maximizing congressmen, agents acting on their behalf, and workers likely to compete with...
