Professor of Finance
Olin Business School
Washington University in St. Louis

I am an economist and a Professor of Finance at the Olin Business School. My areas of expertise include  financial economics, corporate finance, contract theory, and microeconomic theory. 

In my research, I study the behavior of strategic agents in dynamic settings. I am particularly interested in the role of learning in markets with information frictions, with a focus on venture capital, private equity, real estate, and securities markets.  Recently, I have been working on how to design contracts to make credit markets more efficient in developing countries. I also dabble in sports economics.

Prior to joining Olin, I was a tenured associate professor at the Haas School of Business at the University of California, Berkeley. I earned a Ph.D. in Economics from the Stanford Graduate School of Business, a M.S. in financial mathematics from Stanford University, and a bachelor's degree of science in economics and engineering from Duke University.

I am currently serving as an Associate Editor for the Journal of Finance and the Journal of Financial Economics

A few of the projects that I'm working  on right now

(joint with David Sraer)


Recent technological innovations enable creditors to temporarily repossess collateral from their borrowers in order to incentivize repayment. We derive the optimal contract in a canonical principal-agent setting when the principal is endowed with such a technology. We provide necessary and sufficient conditions under which lockout Pareto dominates the traditional repossession technology.

(with Paul Gertler and Catherine Wolfram)

A new form of lending using digital collateral has recently emerged, most prominently in low and middle income countries. Digital collateral relies on ``lockout" technology, which allows the lender to temporarily disable the flow value of the collateral to the borrower without physically repossessing it. We explore the effect of this new form of credit both in a model and in a field experiment
