Welcome to my website!
I'm a PhD candidate at the University of Chicago's department of Economics. My main areas of interest are International Trade, Labor and International Macroeconomics. My research focuses on understanding the impact of temporary sectoral shocks and the role of the dollar as a global currency for both trade and finance.

Working papers
Macroprudential policy for internal financial dollarization (with Aleksei Oskolkov). R&R, Journal of International Economics.
Arguments for limits on foreign currency debt have been based on settings in which firms borrow from foreign investors. However, dollarization can arise as a domestic phenomenon in which firms insure households by borrowing from them in dollars. We revisit the arguments for prudential policy in this empirically relevant setting.
Work in progress
Labor reallocation during commodity booms: The role of uncertainty.
Banks and the geography of capital within borders (with Olivia Bordeu). We study how the distribution of bank branches across cities can matter for the inter-regional allocation of investment and ultimately spatial income differences.
Trade and financial dollarization: Firm-level theory and evidence (with Aleksei Oskolkov). We study the currency invoicing decision of Peruvian exporters during a period of de-dollarization of the national financial system. This sheds light on the different roles that the dollar plays globally in finance and trade.
