Published and Forthcoming Papers

Optimal Dynamic Contracts with Moral Hazard and Costly Monitoring
with Tomasz Piskorski
Journal of Economic Theory 2016, 166: 242-281

We introduce a tractable dynamic monitoring technology into a continuous-time moral-hazard problem. Our results help explain empirical findings on the linkage between termination, performance, pay-performance sensitivity, and monitoring.

Market Selection
with Leonid Kogan, Stephen Ross, and Jiang Wang
Journal of Economic Theory, Forthcoming

We establish straightforward necessary and sufficient conditions for agents making inferior forecasts to survive and to affect prices in a general setting with minimal restrictions on endowments, beliefs, or utility functions.

Looking for Someone to Blame: Delegation, Cognitive Dissonance, and the Disposition Effect
with David H. Solomon and Tom Y. Chang
Journal of Finance 2016, 71(1): 267-302

Investors in most assets are more likely to sell gains than losses, but mutual fund investors do the opposite. Using brokerage data and an experiment, we argue that cognitive dissonance can explain these results and the effects of delegation more generally.

Resource Accumulation Through Economic Ties: Evidence from Venture Capital
with Yael Hochberg and Laura Lindsey
Journal of Financial Economics 2015, 118(2): 245-267
Featured in the Harvard Law School Forum on Corporate Governance and Financial Regulation

We characterize VC firm resources using factor analysis, and we develop a methodology to distinguish motives for coinvestment. Coinvestment is not based on resource similarity; instead it serves to mix value-added resources with capital.

Portfolio Choice with Illiquid Assets
with Andrew Ang and Dimitris Papanikolaou
Management Science 2014, 60(11): 2737-2761
Winner of the Roger F. Murray Prize, Second Place for 2011 (Awarded by the Q-group)

We present a simple model of illiquidity based on trading restrictions of uncertain duration. Uncertainty over trading opportunities is much more important than the simple inability to trade.

Disagreement and Learning in a Dynamic Contracting Model
with Tobias Adrian
Review of Financial Studies 2009, 22(10): 3839-3871
Winner of the CRA International Award for 2007 (Awarded by the Western Finance Association)

We present a dynamic contracting model with disagreement and learning. The interaction between incentive provision and learning creates an intertemporal source of “disagreement risk” that alters optimal risk sharing.

High Water Marks: High Risk Appetites? Convex Compensation, Long Horizons, and Portfolio Choice
with Stavros Panageas
Journal of Finance 2009, 64(1): 1-36
Lead Article

With an indefinite horizon, convex compensation (e.g. high-water marks and other "option-like" contracts) do not generate unbounded risk-taking. In a simple portfolio choice model, we show that risk neutral managers act as CRRA investors.

The Price Impact and Survival of Irrational Traders
with Leonid Kogan, Stephen Ross, and Jiang Wang
Journal of Finance 2006, 61(1): 195-229
Winner of the FAME Research Prize for 2004 (Awarded by the Swiss Finance Institute)
Winner of the Smith-Breeden Prize, First Place for 2006 (Awarded by the American Finance Association)

Price impact and survival are two independent concepts; neither is sufficient for the other. In a simple GE economy, we demonstrate that irrational traders can survive and/or have price impact.
