This paper examines the impact of rising U.S.-China geopolitical tensions on three main dimensions of science: STEM trainee mobility between these countries, usage of scientific works between scientists in each country, and scientist productivity in each country. We examine each dimension from a...

On February 5, 1917, the United States passed the Immigration Act of 1917, which included a test for all migrants arriving to the U.S. to prove they were literate. The Literacy Test was one of the first and few times the U.S. used a broad 'skill-based' immigration policy in an attempt to limit...

This paper shows that the ancestry composition shaped by century-long immigration to the US can explain the current structure of global supply chain networks. Using an instrumental variable strategy, combined with a novel dataset that links firm-to-firm global supply chain information with a US...

How does persecution affect who migrates? We analyze migrants' self-selection out of the USSR and its satellite states before and after the collapse of Communism using census microdata from the three largest destination countries: Germany, Israel, and the United States. We find that migrants...

The close connection between US and China in scientific research and education in the 2000s produced a large group of China-born researchers who work in the US ("diaspora") and a larger group of China-born researchers who gained US-research experience and returned to do their research in China...

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...

The effects of immigration are reasonably well understood in developed countries, but they are far more poorly understood in developing ones despite the importance of these countries as immigrant destinations. We address this shortcoming by studying the effects of immigration to Brazil during...

We study the relationship between firm centralization and organizational reproduction in satellite locations. For decentralized firms, the ethnic compositions of inventors in satellite locations mostly resemble their host cities, with little link to the inventor composition of their parent...

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...

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....
