We use book translations as a new measure of international idea flows and study the effects of Communism's collapse in Eastern Europe on these flows. Using novel data on 800,000 translations and difference-in-differences approaches, we show that while translations between Communist languages...

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...

I reflect on the role of modern economic history in economics. I document a substantial increase in the percentage of papers devoted to economic history in the top-5 economic journals over the last few decades. I discuss how the study of the past has contributed to economics by providing ground...

The United States has admitted more than 3 million refugees since 1980 through official refugee resettlement programs. Scholars attribute the success of refugee groups to governmental programs on assimilation and integration. Before 1948, however, refugees arrived without formal selection...

This paper provides an overview of recent empirical and methodological advances in the study of historical intergenerational mobility trends, with a focus on key measurement challenges. These advances are made possible by the recent digitization of historical censuses and new methods of...

Immigrant enclaves offer valuable ethnic amenities but may delay assimilation. We study enclave formation in the Age of Mass Migration by using the centralized location decisions for "ethnic" Catholic churches. After a church opening, same-ethnicity residents of chosen neighborhoods experienced...

We compile, transcribe, and standardize historical records for 2.5 million students at 65 elite (private and public) U.S. colleges. By combining these data with more recent survey and administrative data, we assemble the largest dataset on the socioeconomic backgrounds of students at American...

We explore how socio-economic background shapes academia, collecting the largest dataset of U.S. academics' backgrounds and research output. Individuals from poorer backgrounds have been severely underrepresented for seven decades, especially in humanities and elite universities. Father's...

We compile large datasets from Norwegian and US historical censuses to study return migration during the Age of Mass Migration (1850-1913). Return migrants were somewhat negatively selected from the migrant pool: Norwegian immigrants who returned to Norway held slightly lower-paid occupations...

Using two million census records, we document cultural assimilation during the Age of Mass Migration, a formative period in US history. Immigrants chose less foreign names for children as they spent more time in the US, eventually closing half of the gap with natives. Many immigrants also...
