I am a PhD candidate in Economics at CEMFI. In this website you can find a copy of my CV and research projects, including my Job Market Paper.

My primary research interests are in the intersection of the fields of banking and finance and macroeconomics . I will be available for interviews at the 2022 European Job Market and in January 2023 during the ASSA meetings.

Working Papers

Sectoral Credit Allocation, Capital Requirements and Financial Stability [Link]
(Job Market Paper)

Banking crises are often preceded by large expansions in residential real estate credit. However, banks' prudential regulation imposes typically lower minimum equity-capital funding requirements on residential real estate lending than on corporate lending. This paper quantifies the consequences of regulatory designs that fail to take into account the macroprudential dimension of the growth in real estate lending. I develop a DSGE model in which banks intermediate real estate loans to households and corporate loans to firms and where abnormally high defaults in either of these sectors can make banks fail. Calibrated for the Euro Area, results show that capital requirements based on the default risk of individual exposures amplify the reallocation of credit towards the real estate sector in the path to banking crises. Distortions to the allocation of credit in the path to crises, as well as the frequency and severity of banking crises, can be better mitigated by sector-specific macroprudential buffers than by generic buffers such as the Countercyclical Capital Buffer (CCyB) of Basel III.

Optimal Capital Requirements and Financial Integration [Link]

This paper studies the welfare implications of changes in regulatory capital requirements in the presence of cross border banking activities. Using a two-country DSGE model with financial frictions, calibrated to match the characteristics of international credit in synthetic Core and Periphery countries in the Euro Area, this paper analyzes the optimal level of Basel-type capital requirements set on corporate loans. Results show that: a) a uniform increase in the level of capital requirements can be welfare improving for both countries, with Core countries preferring lower levels of capital requirements; b) if capital requirements are set in each country separately, it is optimal to impose higher capital requirements for exposures in the Periphery, and c) penalizing the cross border activities of banks with higher capital requirements, even if international loans are more volatile than their domestic counterparts is not, in general, welfare improving.
