How many immigrants with less than university education, for a given immigration quota, maximise economic output? The answer is zero in the canonical model of the labour market, where the marginal product of a university-educated immigrant is always higher. We build an alternative model in which...

The past several decades have witnessed a rebirth of global labor mobility. Workers have begun to move between countries at rates not seen since before World War One. During the same period, economists' study of international migration has been framed by a particular textbook model of location...

In Deutschland fehlt es zusehends an Gesundheitsfachkräften. Daher wächst das Interesse, solche Kräfte auch in Entwicklungsländern zu rekrutieren. Um damit verbundene Probleme für die Herkunftsländer zu vermeiden, orientiert sich die Bundesregierung - wie andere Industrieländer auch - an...

Like many rapidly aging countries Germany is experiencing an increasing lack of health care professionals. There is growing interest also in recruiting health care personnel in developing countries, alongside concerns about potential effects of that recruitment on health overseas. In this...

For decades, migration economics has stressed the effects of migration restrictions on income distribution in the host country. Recently the literature has taken a new direction by estimating the costs of migration restrictions to global economic efficiency. In contrast, a new strand of research...

Large international differences in the price of labor can be sustained by differences between workers, or by natural and policy barriers to worker mobility. We use migrant selection theory and evidence to place lower bounds on the ad valorem equivalent of labor mobility barriers to the United...

Labor markets are increasingly global. Overseas work can enrich households but also split them geographically, with ambiguous net effects on decisions about work, investment, and education. These net effects, and their mechanisms, are poorly understood. We study a policy discontinuity in the...

Purpose – The purpose of this paper is to examine the historical origins of the international goal for rich countries to devote 0.7 per cent of gross national income (GNI) to aid, in order to assess its present relevance. Design/methodology/approach – The paper reviews all the original...

Raising school enrollment, like economic development in general, takes a long time. This is partly because, as a mountain of empirical evidence now shows, economic conditions and slowly-changing parental education levels determine children's school enrollment to a greater degree than education...
