The presence of a westward-moving frontier of settlement shaped early U.S. history. In 1893, the historian Frederick Jackson Turner famously argued that the American frontier fostered individualism. We investigate the Frontier Thesis and identify its long-run implications for culture and politics. We track the frontier throughout the 1790–1890 period and construct a novel, county-level measure of total frontier experience (TFE). Historically, frontier locations had distinctive demographics and greater individualism. Long after the closing of the frontier, counties with greater TFE exhibit more pervasive individualism and opposition to redistribution. This pattern cuts across known divides in the U.S., including urban–rural and north–south. We provide evidence on the roots of frontier culture, identifying both selective migration and a causal effect of frontier exposure on individualism. Overall, our findings shed new light on the frontier’s persistent legacy of rugged individualism.

Rugged Individualism and Collective (In)action during the COVID-19 Pandemic
(with Sam Bazzi and Martin Fiszbein)
Journal of Public Economics, Volume 195, March 2021
Rugged individualism—the combination of individualism and anti-statism—is a prominent feature of American culture with deep roots in the country’s history of frontier settlement. Today, rugged individualism is more prevalent in counties with greater total frontier experience (TFE) during the era of westward expansion. While individualism may be conducive to innovation, it can also undermine collective action, with potentially adverse social consequences. We show that America’s frontier culture hampered the response to the COVID-19 pandemic. Across U.S. counties, greater TFE is associated with less social distancing and mask use as well as weaker local government effort to control the virus. We argue that frontier culture lies at the root of several more proximate explanations for the weak collective response to public health risks, including a lack of civic duty, partisanship, and distrust in science.
Rural Roads, Agricultural Extension, and Productivity
Journal of Development Economics, January 2023
Low agricultural productivity is a persistent challenge for developing economies. Expansions of rural roads and agricultural extension, separately, have been proposed as solutions with mixed effectiveness. In this paper, I show that it is critical to consider roads and extension together due to their strong complementarities. I study the concurrent but independent expansions of rural roads and extension in Ethiopia, and find that, while ineffective in isolation, access to both a road and extension increases productivity by 6%. The key mechanisms include increased take up of advice, adoption of modern inputs, and advantageous shifts in crop choice and labor allocation.

Resettlement and the Agricultural Productivity of Origin Locations (under review)
How do large out-migration shocks affect agricultural productivity in origin lo-cations? Planned resettlements, forced migration, and climate change have resulted in various relocation schemes across the globe. In this paper, I examine the effects of large-scale out-migration on origin locations using a government-mandated resettlement in Ethiopia that relocated over 600,000 people from densely-populated and drought-prone areas. Using a difference-in-differences strategy that exploits plausibly exogenous variation in out-resettlement across districts with similar environmental stressors, I find that agricultural productivity increases in districts with a greater share of out-resettled population. These effects persist for several decades after the end of the resettlement program. Changes in land use facilitated by the out-resettlement may have helped to lessen land degradation and improve agricultural productivity.
Activation of Ethnic Tensions: Resettlement, Diversity, and Conflict in the Long Run
How does diversity affect conflict when intergroup cleavages become salient? Between 1984-86, Ethiopia forcibly resettled over 600,000 people in an emergency program, increasing ethnic diversity across districts. In 2015, unrelated protests over Addis Ababa’s expansion plan triggered a nationwide surge in ethnic salience. Using a difference-in-differences design, I show that historically resettled districts that had been peaceful for years saw more conflicts targeting civilians, perpetrated by militias, when ethnicity became salient. Rising ethnic salience increased in-group identification and eroded interethnic trust. Conflict was severe in less integrated resettlement districts, where the national shock to ethnic relations activated latent local divisions.
Industrial Policy and Misallocation in the Ethiopian Manufacturing Sector
Recent literature highlights that policy induced misallocation of resources across firms within a sector has significant effects on aggregate manufacturing TFP and the overall economic development of a country. In this paper, using a rich plant level census data from 1996-2009, I examine the distortionary effects of two policies designed to support prioritized sub-sectors and regions on the productivity of the Ethiopian manufacturing sector. The first policy, implemented during 1996-2002, was an activist industrial policy favoring import substitution while the second policy, active during 2003-2012, emphasized export promotion. I find that there is a severe misallocation in Ethiopian manufacturing sector, but it has lessened over the studied period. Although improvements in resource allocation across firms of different physical productivity contributed to the observed decline in the dispersion of revenue productivity, there are still large aggregate TFP gains, 92%-180%, from the removal of idiosyncratic distortions. The results suggest that establishment of the priority sector support policies exacerbated the extent of the misallocation, and the sector-based variations (as opposed to location-based) of the policies largely account for the dispersion in revenue productivity. Following the amendment of the first priority sector support policy, the decrease in the within-priority region dispersion of revenue productivity is the driving force for the observed improvements in allocative efficiency.
