"The Price Effects of Liquidity Shocks: A Study of SEC’s Tick-Size Experiment," (with Shiyun Song and Chen Yao) first version November 2017. Revise and Resubmit at Journal of Financial Economics.
This paper provides causal evidence of the impact of the tick size on stock prices. We believe we are the first to offer such evidence in a long literature! We benefit from a unique field experiment that the SEC is presently conducting.
"Are CEOs paid extra for riskier pay packages?," (with Ana Albuquerque, Mary Ellen Carter, and Qi (Flora) Dong) first version July 2018.
We offer a direct test on a fundamental hypothesis in optimal contracting models. According to this hypothesis, incentive pay is expensive to the principal because risk averse agents demand higher pay for riskier pay packages. We find consistent evidence that CEOs with riskier pay packages are paid more, but the additional pay is economically small. Our evidence suggest that CEOs are saturated with incentives.
"Liquidity Provision in the Secondary Market for Private Equity Fund Stakes," (with Johan Cassel, Ludovic Phalippou, and Enrique Schroth) first version May 2018.
This paper finds that asset owners (e.g., pension funds, endowments, banks), not funds specialized in the secondary market (i.e., secondary funds), provide liquidity in times of aggregate liquidity shortages, and that younger and smaller funds are the most exposed to shortages of liquidity.
Analyzes the response of politically active firms to the U.S. Supreme Court decision on Citizens United v. FEC. We estimate that the value of a political connection decreases by $6.9 million after Citizens United. Our evidence supports the hypothesis that independent political spending crowds out political connections. Online Appendix
