Jiasun Li



Assistant Professor of Finance
George Mason University



I received my Ph.D in finance from UCLA Anderson School of Management and B.S. in mathematics from Fudan University (Shanghai, China) prior to joining George Mason. My research interest covers FinTech (including cryptocurrency and crowdfunding), as well as the role of information in the theory of the firm and market microstructure. I have presented research at many prestigious institutions and conferences including MIT, Michigan, Northwestern, Yale, NBER, and Econometric Society. I am a winner of 2016 Yihong Xia Best paper award at CICF and 2014 Chicago Quantitative Alliance (CQA) academic paper competition.

When a group of investors with dispersed private information jointly invest in a risky project, how should they divide the project payoff ? A typical common stock contract rewards investors in proportion to their initial investment, but is it really optimal? This paper first studies as a general contracting problem the role of profit sharing in best harnessing the wisdom of the crowd, then investigates a specific application to the security design of investment crowdfunding.

I show that simple profit-sharing contracts with decentralized control could empower individuals with their collective wisdom by coordinating actions guided by dispersed private information. This result parallels existing theories for financial markets, where the equilibrium market price achieves an information aggregation effect through rational expectations. The wisdom of the crowd effect of a well-designed profit-sharing contract speaks to optimal corporate governance structures, guides security design for some new financing practices such as crowdfunding, and sheds new light on the nature of the firm: joint-stock companies endogenously emerge to complete the market.

Almost all U.S. firms now announce earnings outside of regular trading hours. This paper studies how stock prices incorporate information in after-hours trading. I find slow prices adjustment accompanied by significant trading volume. During 2002-2012, 5,881 rule-based trading opportunities generate an average return of 1.53% within four hours. After costs (assessed by a trading experiment), an investor who properly exploits the slow adjustment beats the market by 11.5% per year. The slow price adjustment persists under various levels of investor inattention, limited arbitrage capital, short-sale constraints, and market liquidity.
