The boll weevil spread across the Southern United States from 1892 to 1922 having a devastating impact on cotton cultivation. The resulting shift away from this child labor–intensive crop lowered the opportunity cost of attending school, and thus the pest increased school enrollment and...

We study the importance of discretion in antitrust enforcement by analyzing the response of asset prices to the sudden accession of Theodore Roosevelt to the presidency. During McKinley's term in office the largest wave of merger activity in American history occurred, and his administration did...

This paper examines the effect of ethnic enclaves on economic outcomes of Norwegian immigrants in 1910 and 1920, the later part of the Age of Mass Migration. Using different identification strategies, including county fixed effects and an instrumental variables strategy based on chain migration,...

We provide the first estimates of ethnic segregation between 1850 and 1940 that cover the entire United States and are consistent across time and space. To do so, we adapt the Logan-Parman method to immigrants by measuring segregation based on the nativity of the next-door neighbor. In addition...

This paper examines the long-run effects of the 1906 San Francisco Earthquake on the spatial distribution of economic activity in the American West. Using variation in the potential damage intensity of the earthquake, we show that more severely affected cities experienced lower population...

The nullification of slave wealth after the U.S. Civil War (1861-65) was one of the largest episodes of wealth compressions in history. We document that white Southern households holding more slave assets in 1860 lost substantially more wealth by 1870, relative to households that had been...

Using data over more than a century, we show that shifts in the location of manufacturing industries are a domestic reflection of what the international trade literature refers to as the product cycle in a cross-country context, with industries spawning in high-wage areas with larger pools of...

The COVID-19 pandemic has reignited interest in responses to the 1918-19 influenza pandemic, the last comparable U.S. public health emergency. During both pandemics, many state and local governments made the controversial decision to close schools. We study the short- and long-run effects of...

Using novel data on 50,000 Norwegian men, we study the effect of wealth on the probability of internal or international migration during the Age of Mass Migration (1850-1913), a time when the US maintained an open border to European immigrants. We do so by exploiting variation in parental wealth...

The Age of Mass Migration (1850-1913) was among the largest migration episodes in history. During this period, the United States maintained open borders. Using a novel dataset of Norway-to-US migrants, we estimate the return to migration while accounting for migrant selection across households...
