Executive summary

My research spans dynamic contracting, international finance, and financial intermediation. 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,” “Markup cycles, dynamic misallocation, and amplification," 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.


Research overview:

Research statement

1) Financial regulation, financial intermediaries (banks, rating agencies): (4), (8), (9), (10).

2) Contract and relationship dynamics: (3), (5), (6), (9).

3) International/ macro: trade theory, DSGE models: (1), (2), (5).





(7) "Target Revaluation after Failed Takeover Attempts - Cash versus Stock," 2016, joint with Ulrike Malmendier and Farzad Saidi, Journal of Financial Economics, 119, 92-106. Online Appendix

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.


(6) “Impatience versus incentives,” 2015, joint with John Zhu, Econometrica, 83, 1601-1617. Presentation Slides from Econometric Society Meeting, Boston 2015.

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.


(5) “Markup cycles, dynamic misallocation, and amplification," 2014, joint with Christine Parlour & Johan Walden, Journal of Economic Theory, 154, 126-161.
Main insight: We analyze the IO implications of consumption-based asset pricing. In contrast to a risk-neutral economy, oligopolistic competition produces procyclical aggregate markups if valuations are governed by preferences with a relative risk aversion coefficient greater than 1. With heterogeneous industries, aggregate fluctuations may originate purely from myopic strategic behavior at the industry-level.


(4) ''Rating agencies in the face of regulation,'' 2013, joint with Christian C. Opp & Milton Harris, Journal of Financial Economics, 108, 46-61.
Abridged version of paper for Fame magazine.
Main insight: The regulatory use of ratings feeds back into the ratings of profit-maximizing credit rating agencies. Rating inflation is expected to occur for complex securities.


(3) "Expropriation risk and technology,'' 2012, Journal of Financial Economics, 103, 113-129.
Main insight: Property rights (within a country) vary across industrial sectors according to their technology intensity, leading to a pecking order of expropriation. Firms can manage expropriation risk by forming conglomerates.


(2) "Tariff wars in a Ricardian model with a continuum of goods," 2010, Journal of International Economics, 80, 212-225.
Main insight: Optimum import tariff rates in the Dornbusch-Fischer-Samuelson model of trade are increasing in both absolute advantage and comparative advantage. A sufficiently large economy prefers the Nash equilibrium of tariffs over free trade.

(1) "Rybczynski's theorem in the Heckscher-Ohlin world - anything goes," 2009, joint with Hugo Sonnenschein & Christis Tombazos, Journal of International Economics, 79, 137-142.
Main insight: The predictions of the Rybczynski Theorem can be reversed in general equilibrium. This "reverse" outcome implies immiserizing factor growth.

Working papers:

(8) “Bank risk-taking and the composition of credit supply,” December 2016, joint with Milton Harris and Christian Opp. See Video for intuition of graphical illustration of main results.

Abstract: We develop a tractable general equilibrium framework to understand the implications of banks' risk-taking incentives for the composition of credit supply. Our setup permits a rich cross-sectional distribution of borrower characteristics. Banks endogenously specialize in financing different segments of this distribution to align loan payoff states with their own survival states. The equilibrium typically features simultaneous overinvestment, banks crowding out public markets, and, underinvestment for different borrower types. Our framework highlights the importance of incorporating distributions of borrower types into bank regulators' workhorse models to gauge the effects of policy interventions such as capital injections or changes in capital requirements.

(9) “Only time will tell: a theory of deferred compensation and its regulation,” December 2016, joint with Florian Hoffmann and Roman Inderst, Presentation Slides.
Abstract: We characterize optimal contracts in settings where the principal observes informative signals over time about the agent's one-time action. If both are risk-neutral contract relevant features of any signal process can be represented by a deterministic “informativeness” process that is increasing over time. The duration of pay trades off the gain in informativeness with the costs resulting from the agent's liquidity needs. The duration is shorter if the agent's outside option is higher, but may be non-monotonic in the implemented effort level. We evaluate effects of regulatory proposals that mandate the deferral of bonus payments and use of clawback clauses.

Work in progress:

(10) “Regulatory reform and risk-taking: replacing ratings,” September 2014, joint with Bo Becker, Presentation slides. (major update soon, new data!)

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.
