My research interests include agricultural and resource economics, labor economics, demographic economics, and economic history. I have focused my research on inter-generational occupation choices, farm succession, rural migration, and rural mortality in the US.

The Dust Bowl and Occupational Persistence in US Agriculture (Link to Job Market Paper)
In the 1930s, the United States experienced an environmental catastrophe caused by dust storms and drought, known as the Dust Bowl. This paper investigates whether this environmental shock affected occupational persistence—whether children follow in their parents’ footsteps by choosing the same occupation—when it comes to agriculture. I find that occupational persistence rates decreased by 2% after the Dust Bowl in high-erosion counties compared to low-erosion counties. Children of farmers were 15% less likely to become self-employed farmers and 10% more likely to work as paid farm workers. Furthermore, children who migrated out from Dust Bowl-affected areas were more likely to work off-farm. This study identifies that the structural transformation the US economy underwent over the course of the 20th century may have been helped by the Dust Bowl.
Compulsory Education and Occupational Persistence: Evidence from US Agriculture
This paper examines the impact of US compulsory education laws on occupational persistence in agriculture. Using the US Decennial Census Data and the Census of Agriculture from 1860 to 1910 and the Difference-in-Difference model, findings indicate a significant 8% reduction in the probability of farm household children becoming farmers. Heterogeneity analysis by gender, birth order, and race indicates that disadvantaged groups were more likely to transition from agricultural to non-agricultural sectors. Concurrently, farm numbers declined while average farm size increased, suggesting farm consolidation. This study shows evidence that US compulsory education laws play a role in accelerating structural transformation.
