This paper analyses the impact of networks on the structure of international migration flows to OECD countries. In particular, we look at whether diaspora effects are different across education levels and gender. Using new data allowing to include both dimensions, we are able to analyze the...

This paper studies the impact of low-skilled immigration on the host country’s education system, which is characterized by sources of school funding, expenditres per pupil, and types of parents who are more likely to send children to publicly (privately) funded schools. When the size of...

The role of migrants’ networks in promoting cross border investments has been stressed in the literature, possibly making migration and FDI complements rather than substitutes in the long run. In this paper, we estimate the magnitude of such business network externalities in dynamic empirical...

The aim of this paper is to highlight the positive and important role that skilled migration can have on TFP growth in the sendind countries, when diaspora effects in technology diffusion are introduced. To investigate our issue, we start from a previous paper by Vandenbussche, Aghion and Costa...

In this paper I consider two symmetric countries/regions which trade in final goods. In each country is active the manufacturing sector and both vertical and horizontal innovation conduced by individuals with heterogenous ability. I show that a more globalized world, as represented by lower...

This paper updates and extends the Docquier-Marfouk data set on international migration by educational attainment. We use new sources, homogenize definitions of what a migrant is, and compute gender-dissaggregated indicators of the brain drain. Emigration stocks and rates are provided by level...

The aim of this paper is to develop a dynamic model of migrations, in which migration is driven by size asymmetries between countries and by the relative preferences of consumers between private consumption and consumption of public goods. The dynamic trajectories heavily depend on the degree of...

Migration flows are shaped by a complex combination of self-selection and out-selection mechanisms. In this paper, we analyze how existing diasporas (the stock of people born in a country and living in an another one) affect the size and human-capital structure of current migration flows. Our...

Existing migrant networks play an important role in explaining the size and structure of immigration flows. They affect the net benefits of migration by reducing assimilation costs (’self-selection channel’) and by lowering legal entry barriers through family reunification programs...

Emigration affects institutions at home in a number of ways. While people may have fewer incentives to voice when they have exit options, emigrants can voice once abroad and contribute to the diffusion of democratic values and norms. We first document these channels and then consider...
