My research spans dynamic contracting, financial intermediation, and international finance. My most recent work on financial intermediation analyzes the interplay between financial regulation and risk-taking incentives in the financial sector. The corresponding papers are published in top general interest journals (Econometrica) and leading field journals such as the Journal of Economic Theory, the Journal of Financial Economics and the Journal of International Economics. My favorite papers are “Impatience versus incentives,” “Only time tell: A theory of deferred compensation and its regulation," and ''Rating agencies in the face of regulation.'' I have been a board member of the Finance Theory Group since September 2016. I have achieved teaching excellence at Berkeley Haas (Median score = 6 / 7) in every section since 2010 across a variety of degree programs (undergraduate, M.B.A. and Ph.D.). Last rating: 6.3 / 7 in MBA core finance course in Spring 2016. I won the 2017 Poets and Quants "Top 40 under 40" award for professors of world-wide business schools.

Main insight: Capital markets interpret a cash offer as a economically large and positive signal about the fundamental value of target resources (in contrast to a stock offer). We expose a significant look-ahead bias affecting the previous literature on this topic.
Main insight: We study the dynamics of contracts in repeated principal-agent relationships with an impatient agent. Despite the absence of exogenous uncertainty, Pareto-optimal dynamic contracts generically oscillate between favoring the principal and favoring the agent.

(8) “Bank capital, risk-taking, and the composition of credit,” January 2017, joint with Milton Harris and Christian Opp. See Video for intuition with graphical illustration.
Abstract: We propose a general equilibrium framework to analyze the cross-sectional distribution of credit and its exposure to shocks to the financial system, such as changes to bank capital, capital requirements, and interest rates. We characterize how over- and underinvestment in different parts of the borrower distribution are linked to the capitalization of the banking sector and the distribution of borrowers' risk characteristics and bank dependence. Our model yields a parsimonious asset pricing condition for firms' cost of capital that sheds light on heterogeneity in interest rate pass-through across borrower types, as well as its dependence on the health of the banking sector.

Abstract: We expose that a reform of capital regulation for insurance companies in 2009/2010 eliminated (to a first-order approximation) capital requirements for holdings of non-agency mortgage backed securities. Post reform, insurance companies allocate 54% of their purchases of new MBS issues toward non-investment grade assets (as opposed to 6% pre reform), a large increase in risk-taking.
