Welcome to my website! I am with the U of Iowa as a Visiting Assistant Professor of Finance. I got a Ph.D. in Finance after spending 5 years at the U of Arizona in Tucson, and dual B.A. degrees in Economics and Law after 4 years at Nankai University in Tianjin, China. I also conducted academic research at Equifax in Atlanta and at the National Institute of Financial Research, Tsinghua University in Beijing.
I am interested in understanding factors that drive economic agents’ decision making and the implications of these choices for investment performance, financial fragility, and firm value. I am passionate about generating novel insights in finance by integrating perspectives from information economics, labor economics, industrial organization, and law and economics. My current research focuses on hedge funds, mutual funds, private equity, and insurance.
I will be on the 2026-2027 job market. You can reach me at ygao108fin@gmail.com.

[1] AI Automation and Effort Allocation: Evidence from Sophisticated Investors
Do high-skilled workers exert more effort at human-intensive tasks in the AI era? I hypothesize that AI automates sophisticated investors’ machine-based information acquisition tasks, thereby shifting effort toward human-interaction-based ones. Using an event-study design and a shift-share IV strategy, I find a significant increase in hedge funds’ earnings call participation—along both extensive and intensive margins—following their adoption of automated downloads of SEC filings. Funds’ post-automation call attendance is associated with higher returns and more profitable stock trades. Overall, this study empirically identifies a novel effort-reallocation mechanism through which automation raises productivity for high-skilled workers performing partially automatable tasks.

[2] Whom You Know Matters: Mutual Fund Workplace Networks and Investment Performance
Do investors rely on workplace networks and what organizational structures facilitate workplace information flows? We provide new insights by constructing a novel fund-level skill-weighted measure of interfund comanager connections (ICC). We find that funds with a higher ICC exhibit more similar portfolio holdings to connected funds. A higher ICC is also associated with better fund performance. We use plausibly exogenous superstar manager departures to pin down causality. Value-relevant information is transmitted: ICC funds profit more from trading on overlapped hard-to-research stocks and non-local stocks than non-ICC funds. We also present first evidence on the evolution of mutual fund workplace networks.

[3] Prices versus Voices: Dissecting the Governance Epitome of Passive Investing
I provide novel evidence on the governance implications of passive investing through the lens of CEO turnover-performance sensitivity (TPS). I formulate competing hypotheses that passive ownership affects CEO TPS via less informative stock prices or stronger governance-related shareholder voices. Using Russell index reconstitutions to perform difference-in-discontinuity estimations and shock-based IV analyses, I show that the consistent positive relation between passive ownership and CEO TPS is likely causal, consistent with large passive voting blocks amplifying active shareholders’ ability to press for stronger governance. Poorly performing CEOs being replaced is seen as a bright side of passive ownership by the stock market.
