I examine the determinants of inter-state migration of adults within western Germany, using the German Socio-Economic Panel from 1984-2000. I highlight the prevalence and distinctive characteristics of migrants who do not change employers. Same-employer migrants represent one fifth of all...

Allowing migration activity as an integral part of demographic transition and economic development, we establish a locational quantity-quality trade-off of children and explore its macroeconomic consequences. We construct a dynamic competitive migration equilibrium framework with rural agents...

The 1930's American Dust Bowl created archetypal "Dust Bowl migrants," refugees from environmental collapse and economic upheaval. I examine this archetype, comparing migration from more-eroded counties and less-eroded counties to distinguish Dust Bowl migrants from other migrants in this era....

Exploiting a large migration of farmers to the West of Brazil between 1950 and 2010, we study how migration shapes aggregate and regional comparative advantage. We document that farmers emigrating from regions with high employment in an activity are more likely to work in that activity and have...

How integrated are labor markets within a country? Labor mobility is key to the integration of local labor markets and therefore to understanding the efficacy of policies to reduce regional inequality. We present a comprehensive framework for understanding migration decisions, focusing on the...

We investigate the role of information frictions in migration. We develop novel moment inequalities to estimate worker preferences while allowing for unobserved worker-specific information sets, migration costs, and location-specific amenities and prices. Using data on internal migration in...

From the beginning of the Covid-19 pandemic to late 2021, international immigration flows to the US decreased significantly. We document the timing and the characteristics of these significant changes in flows, their evolution until late 2022 and their geographic and sector distribution. We...

Internal migration in the United States has declined substantially over the past several decades, which has important implications for individual welfare, macroeconomic adjustments, and other key outcomes. This paper studies the determinants of internal migration and how they have changed over...

This paper introduces the concept of "climate matching" as a driver of migration and establishes several new results. First, we show that climate strongly predicts the spatial distribution of immigrants in the US, both historically (1880) and more recently (2015), whereby movers select...

We develop a general equilibrium model of frictional labor reallocation across firms and regions, and use it to quantify the aggregate and distributional effects of spatial frictions that hinder worker mobility across regions in Germany. The model leverages matched employer-employee data to...
