The American Civil War fractured communities in border states where families who would eventually support the Union or the Confederacy lived together prior to the conflict. We study the subsequent migration choices of Civil War veterans and their families using a unique longitudinal dataset covering enlistees from the border state of Kentucky. Nearly half of surviving Kentucky veterans moved to a new county between 1860 and 1880. We find strong evidence of sorting along ideological dimensions for veterans from both sides of the conflict. However, we find limited evidence of a positive economic return to these relocation decisions.

I find that childhood exposure to the Dust Bowl, an environmental shock to health and income, adversely impacted later-life human capital—especially when exposure was in utero—increasing poverty and disability rates, and decreasing fertility and college completion rates. The event's devastation of agriculture, however, had the beneficial effect of increasing high school completion, likely by pushing children who otherwise might have worked on the farm into secondary schooling. Lastly, New Deal spending helped remediate Dust Bowl damage, suggesting that timely and substantial policy interventions can aid in human recovery from natural disasters.

This article examines the impact of the 1850 Austro-Hungarian customs union on production land-use outcomes. Using newly digitized data from the Second Military Survey of the Habsburg Monarchy, we apply a spatial discontinuity design to estimate the impact of trade liberalization on land use. We find that the customs union increased cropland area by 8 percent per year in Hungary between 1850 and 1855, while forestland area decreased by 6 percent. We provide suggestive evidence that this result is not confounded by the emancipation of the serfs, population growth, or technological change in agriculture.

I analyzed the market of paintings in Florence and Italy (1285–1550). Hedonic regressions on real prices allowed me to advance evidence that the market was competitive and that an important determinant of artistic innovation was driven by economic incentives. Price differentials reflected quality differentials between painters as perceived at the time (whose proxy is the length of the biography of Vasari) and did not depend on regional destinations, as expected under monopolistic competition with free entry. An inverse-U relation between prices and age of execution is consistent with reputational theories of artistic effort, and prices increased since the 1420s.

We use a new trade dataset showing that nineteenth century sub-Saharan Africa experienced a terms of trade boom comparable to other parts of the “global periphery.” A sharp rise in export prices in the five decades before the scramble (1835–1885) was followed by an equally impressive decline during the colonial era. This study revises the view that the scramble for West Africa occurred when its major export markets were in decline and argues that the larger weight of West Africa in French imperial trade strengthened the rationale for French instead of British initiative in the conquest of the interior.

The 1918 Influenza Pandemic killed millions worldwide and hundreds of thousands in the United States. This article studies the impact of air pollution on pandemic mortality. The analysis combines a panel dataset on infant and all-age mortality with a novel measure of air pollution based on the burning of coal in a large sample of U.S. cities. We estimate that air pollution contributed significantly to pandemic mortality. Cities that used more coal experienced tens of thousands of excess deaths in 1918 relative to cities that used less coal with similar pre-pandemic socioeconomic conditions and baseline health. Factors related to poverty, public health, and the timing of onset also affected pandemic mortality. The findings support recent medical evidence on the link between air pollution and influenza infection, and suggest that poor air quality was an important cause of mortality during the pandemic.

Most studies of female workers in the 1940s focus on labor supply. We use the basics of supply and demand to measure the impact of WWII on the short- and medium-run demand for female workers in manufacturing. Demand rose for both salaried and production female workers during the war and then fell after the war. However, the post-war demands for both groups were substantially higher than before the war and higher than the levels that would have been reached had the demands followed a counterfactual growth path from the boom period in the 1920s.

Structural transformation is a key indicator of economic development. We present the first time series of male labor sectoral shares for England and Wales before 1800, using a large sample of probate and apprenticeship data to produce national- and county-level estimates. England experienced a rapid decline in the share of workers in agriculture between the early seventeenth and the beginning of the eighteenth centuries, associated with rising agricultural and especially industrial productivity; Wales saw few changes. Our results show that England experienced unusually early structural change and highlight the mid-seventeenth century as a turning point.

Big data is an exciting prospect for the field of economic history, which has long depended on the acquisition, keying, and cleaning of scarce numerical information about the past. This article examines two areas in which economic historians are already using big data – population and environment – discussing ways in which increased frequency of observation, denser samples, and smaller geographic units allow us to analyze the past with greater precision and often to track individuals, places, and phenomena across time. We also explore promising new sources of big data: organically created economic data, high resolution images, and textual corpora.

In nineteenth century Britain atmospheric pollution from coal-fired industrialization was on the order of 50 times higher than today. We examine the effects of these emissions on child development by analysing the heights on enlistment during WWI of men born in England and Wales in the 1890s. We find a strong negative relationship between adult heights and the coal intensity of the districts in which these men were observed as children in the 1901 census. The subsequent decline in atmospheric pollution likely contributed to the long-term improvement in health and increase in height.

We estimate the effect of age at arrival for immigrant outcomes with a new dataset of arrivals linked to the 1940 U.S. Census. Using within-family variation, we find that arriving at an older age, or having more childhood exposure to the European environment, led to a more negative wage gap relative to the native born. Infant arrivals had a positive wage gap relative to natives, in contrast to a negative gap for teenage arrivals. Therefore, a key determinant of immigrant outcomes during the Age of Mass Migration was the country of residence during critical periods of childhood development.
