Between 1940 and 1970, more than 4 million African Americans moved from the South to the North of the United States, during the Second Great Migration. This same period witnessed the struggle and eventual success of the civil rights movement in ending institutionalized racial discrimination....

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 provides a novel perspective on the Great Migration out of the U.S. South. Using a shift-share identification strategy, we show how millions of Southern white migrants transformed the cultural and political landscape across America. Counties with a larger Southern white share by 1940...

This paper has two goals: first to describe a theoretical model which derives relationships among migration decisions explicitly from utility maximization under uncertainty; and second, to examine why nations vary in their internal migration. To explain variation in internal migration, we...

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...

Recent studies find that observational returns to rural-urban migration are near zero in three developing countries. We revisit this result using panel tracking surveys from six countries, finding higher returns on average. We then interpret these returns in a multi-region Roy model with...

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....

The Great Migration from the US South is a prominent theme in economic history research not only because it was a prime example of large scale internal migration, but also because it had far-reaching ramifications for American economic, social, and political change. This essay offers a concise...

There is a long-standing debate among academics about the effect of immigration on native internal migration decisions. If immigrants displace natives this may indicate a direct cost of immigration in the form of decreased employment opportunity for native workers. Moreover, displacement would...

We follow the careers 1981-2004 of 5401 star scientists listed in ISI HighlyCitedSM as most highly cited by their peers. Their number in a US region or a top-25 science and technology (S&T) country significantly increases the probability of firm entry in the S&T field in which they are working....
