A growing number of OECD countries are leaning toward adopting quality-selective immigration policies. The underlying assumption behind such policies is that more skill-selection should raise immigrants' average quality (or education level). This view tends to neglect two important dynamic...

The number of migrants from conflict regions in Africa has been increasing dramatically. The European Union shares dual responsibility for the continuing migration pressure: First, because it fostered over decades corrupt and autocratic regimes with dire disregard to principles of "good...

In response to surging immigration pressure in Europe and the United States, Western policymakers advocate foreign aid as a means to fight the 'root causes' of irregular migration. This article provides the first global evidence of the effects of aid on migration preferences, migration flows,...

This article is the first to systematically study whether foreign aid affects the net flows of refugees from recipient countries. Combining refugee data on 141 origin countries over the 1976-2013 period with bilateral Official Development Assistance data, we estimate the causal effects of a...

This paper investigates through which channels foreign aid impacts migration to donor countries. To disentangle the non-donor-specific channels (development and credit constraint channels) from the donor-specific channels (information and instrumentation channels), we use the fact that...

Why do people leave high-income countries with extensive welfare states? This article will examine what underlies the emigration intentions of native-born inhabitants of one industrialized country in particular: the Netherlands. To understand emigration from high-income countries we focus not...

Discussions of high-skilled mobility typically evoke migration patterns from poorer to wealthier countries, which ignore movements to and between developing countries. This paper presents, for the first time, a global overview of human capital mobility through bilateral migration stocks by...

Migration decisions affect those left-behind in ways that are partly taken into account by market forces (e.g., wage effects on labour markets) and for the most part these can be seen as pure externalities. Diasporas are an example of such an externality. This paper reviews the recent economic...

This paper critiques the last decade of research on the effects of high-skill emigration from developing countries, and proposes six new directions for fruitful research. The study singles out a core assumption underlying much of the recent literature, calling it the Lump of Learning model of...
