I am an assistant professor of finance at the City University of Hong Kong (CityU). My research is empirical and focuses on issues in corporate governance, labor mobility, and entrepreneurship. I teach corporate finance and international finance in the undergraduate and graduate economics and finance programs at CityU. I earned my PhD from UCLA Anderson School of Management in 2017.
Director Networks, Mobility, and Governance: Evidence from Corporate Bankruptcies
with Nimesh Patel
We exploit a quasi-natural experiment to investigate how directors' reliance on professional connections in their search for new directorships impacts board composition and corporate governance policies. For directors who have not held board positions or employment at bankruptcy-filing firms, we find that those who nevertheless have current or past connections to other directors with explicit work histories at bankruptcy-filing firms experience a decline in mobility around the time of filing: directors with these connections have a 5 percent lower chance of finding new board positions within a year. Additionally, we find these suspended director network ties make board recruitment of new directors more difficult. As a result, average board size decreases and average director tenure increases. Lastly, we provide evidence that director mobility can interfere with corporate governance, as firms with less mobile directors show improvements in shareholder rights.

How do Passive Funds Act as Active Owners? Evidence from Mutual Fund Voting Records

The rise of passive institutional investors in the U.S. stock market raises questions about the governance implications of their portfolio firms. While the existing literature documents various governance changes in response to changes in passive ownership, it remains unclear through what mechanism such changes take place. We address this question by comparing the proxy voting records of passive and active funds. We find that compared to their active peers within the same fund family, passive funds often exert corporate governance changes on portfolio firms not via how they vote for a given proxy ballot, but rather by influencing what proxy items get included on the ballot in the first place. Our results support a “behind-the-scene” intervention argument on how passive funds approach corporate governance of their portfolio firms.
Profit Windfalls and Investment Channels in Innovation: Evidence from Patent Term Extensions
I show that capital expenditure, debt issuance, and patent acquisitions are sensitive to cash flow for mature innovating firms. By exploiting the random timing of patent term expiry dates and their unexpected extensions around the adoption of a provision in the Uruguay Round Agreements Act, I find that a one standard deviation increase in the citation-weighted patent portfolio share of term-extended patents leads to an increase in cash flow by 1.5 percent of book assets. Given these windfall profits, I find evidence of physical capital investment, debt issuance reduction, and acquisitions of external technology. Internal investments in R&D, on the other hand, show no response, suggesting high R&D adjustment costs for large, mature firms.
