I am a PhD candidate in Economics at New York University. My research interests include Macroeconomics, Urban Economics, and Real Estate.

I will be available for interviews at the CEEE meeting in Toronto (Dec 2019), the EEA meeting in Rotterdam (Dec 2019), and the ASSA meeting in San Diego (Jan 2020).

I investigate the extent to which land-use restrictions, through their impact on house prices, act as a barrier to labor mobility. To do so, I develop a multi-region heterogeneous agents model of migration and housing, where land-use restrictions act as a friction affecting the productivity of land and the housing supply. Using the structure of the model, along with data on regional prices, output, and housing densities, I estimate a measure of implied restrictions across a panel of U.S. states. Consistent with the existing measure of restrictions, the model-implied measure suggests that restrictions are most stringent in regions with high incomes and house prices. Further, the measure shows that the states that were most restricted in the past have become even more restrictive over time. I calibrate the model to 2014 and show that the variation in regional productivities and land-use restrictions generate the income and house price gaps observed in the data. Performing a counterfactual exercise, I find that lowering the level of restrictions in California back to its level in 2000 results in a large reallocation of labor. The state's population rises by 45%, while the income gap and house value gap between California and the rest of the U.S. falls by 3.7% and 2.7%, respectively. I also study the importance of borrowing constraints and moving costs in hindering labor mobility and find that conditional on the observed income and house price gaps, neither plays a significant role.
