Opportunities and Risks in Belief Distribution Elicitations

Researchers and practitioners have increasingly embraced the novel practice of eliciting the entire belief distributions, as it provides a more thorough understanding of stakeholders’ beliefs. My recent paper (co-authored with Professor Joe Simmons) suggests that constructing belief distributions can sometimes inadvertently exacerbate people’s overconfidence in their predictions. Read More
Are ETFs better than Mutual Funds?

I study investors’ trade-off between ETFs and open-ended mutual funds in the presence of idiosyncratic liquidity risk and aggregate uncertainty. Based on a portfolio choice model, I show that ETFs and mutual funds provide liquidity at different maturities. Read More
Learning by Monitoring: The Impact of Monitoring on VC Re-Investment Performance

This project aims to investigate the impact of monitoring on VC reinvestment performance.

Resetting the Clock: Dynamic Goal Setting Using Behavior Tracking Technology

Can companies providing goal-tracking technology innovate their products to better enable consumers to keep going when they inevitably fail (i.e., skip a workout or overeat calories)? Our research aims to fill this gap by testing the effectiveness of one type of goal tracking design: dynamic goal setting. Most traditional goal tracking apps focus on static ...Read More
Innovating Shift Work Design to Incorporate Heterogeneous Worker Preferences

Shifts are the dominant way to work in many contexts requiring 24/7 coverage, including call centers, police departments, and hospitals. While the detriments of shift work are well-documented both at the individual and organizational levels, its deployment is often unavoidable given round-the-clock staffing needs. We explore a potential organizational lever—incorporating heterogeneous preferences over shift design—to ...Read More

Research from other sectors has shown that PE firms apply best-in-class management practices to improve productivity and ...Read More
