I study the internal migration of native-born white men in the United States using linked census data covering all possible 10- and 20-year periods 1850--1940. Inter-county migration rates were stable over time. Selection into migration on the basis of occupational status was also largely stable...

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...

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...

We study how recent gentrification shocks impact Black and Hispanic neighborhoods, including where minority households move to after a shock and if the subsequent spatial distribution of households within a labor market area affects segregation. We first report that household moves from a given...

Migration is a key mechanism through which local labor markets adjust to economic shocks. In this paper, we analyze the migration response of American workers to two of the most important shocks that hit US manufacturing since the 1990s: Chinese import competition and the introduction of...

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...

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...

We develop a dynamic spatial growth model to explore the role of trade and internal migration in the process of spatial development and aggregate growth. Growth is shaped by the best global and local ideas that contribute to the local stock of knowledge. Global ideas diffuse more to locations...

This paper explores how historical gender roles become entrenched as norms over the long run. In the historical United States, gender roles on the frontier looked starkly different from those in settled areas. Male-biased sex ratios led to higher marriage rates for women and lower for men. Land...

This paper studies how agricultural production responds to the loss of agricultural labor during the process of urbanization and structural transformation. Using household microdata from India and exogenous variation in migration opportunities induced by urban income shocks, we show that...
