We bring to bear a novel dataset covering the employment history of about 450 million individuals from 180 countries to study return migration and the impact of skilled international migration on human capital stocks across countries. Return migration is a common phenomenon, with 38% of skilled...

Do new migration opportunities for rural households change the nature and extent of informal risk sharing? We experimentally document that randomly offering poor rural households subsidies to migrate leads to a 40% improvement in risk sharing in their villages. We explain this finding using a...

Argentina was the second largest destination country during the Age of Mass Migration, receiving nearly six million migrants. In this article, we first summarize recent findings characterizing migrants' long-term economic assimilation and their contributions to local economic development. The...

In this article we revive, extend and improve the approach used in a series of influential papers written in the 2000s to estimate how changes in the supply of immigrant workers affected natives' wages in the US. We begin by extending the analysis to include the more recent years 2000-2022....

Foresightful workers can take actions to reduce their exposure to risk in labor markets, but existing evidence on narrow bracketing suggests that individuals might not optimally integrate risk reduction decisions with subsequent labor decisions. In an online labor market, we vary the level of...

We develop and estimate a life-cycle consumption savings model in which observed genetic variation is allowed to affect wealth accumulation through several distinct channels. We focus on genetic markers that predict educational attainment, aggregated into a predictive index called a polygenic...

This paper presents a theoretical and empirical study of the economic progress experienced by immigrants in the U.S. labor market. The theoretical framework illustrates that the relationship between the entry wage of immigrants and the subsequent rate of wage growth depends on the technology of...

Using a human capital based growth model, we show the essential role of labor mobility and cross-country tax harmonization in equalizing income levels of countries that start off from different initial income positions. Knowledge spillovers cum labor mobility are the driving forces behind the...

By allowing for imperfectly informed markets and the role of private information, we offer new insights about observed deviations of portfolio concentrations in domestic relative to foreign risky assets, or "home bias", from what standard finance models predict. Our model ascribes the "bias" to...
