We use recent immigration data from 195 countries and propose an index of population diversity based on people's birthplaces. This new index is then decomposed into a size (share of foreign born) and a variety (diversity of immigrants) component and is available for 1990 and 2000 disaggregated...

Migration is an important and yet neglected determinant of institutions. The paper documents the channels through which emigration affects home country institutions and considers dynamic-panel regressions for a large sample of developing countries. We find that emigration and human capital both...

Migration contributes to the circulation of goods, knowledge, and ideas. Using community and individual-level data from Moldova, we show that the emigration wave that started in the late 1990s strongly affected electoral outcomes and political preferences in Moldova during the following decade...

The gravity model has provided a tractable empirical framework to account for bilateral flows not only of manufactured goods, as in the case of merchandise trade, but also of financial flows. In particular, recent literature has emphasized the role of information costs in preventing larger...

We empirically investigate the relationship between a country's economic complexity and the diversity in the birthplaces of its immigrants. Our cross-country analysis suggests that countries with higher birthplace diversity by one standard deviation are more economically complex by 0.1 to 0.18...

We investigate the relationship between the presence of migrant inventors and the dynamics of innovation in the migrants' receiving countries. We find that countries are 25 to 60 percent more likely to gain advantage in patenting in certain technologies given a twofold increase in the number of...
