Current Research

Working Papers

Three papers study how firms adjust monitoring, prices, and team incentives when legal liability, climate regulation, and performance measures change managerial risk.

Executive Liability and Internal Monitoring

Job Market Paper

Solo-authored. Draft: April 2026.

I examine whether reducing executive liability changes firms' demand for internal monitoring. Delaware's 2022 officer-exculpation reform authorized corporations to adopt charter provisions limiting covered officers' monetary liability for eligible duty-of-care breaches. Using firm-quarter job postings from U.S. public firms, I compare Delaware-incorporated firms with non-Delaware firms in a difference-in-differences design. Following the reform, the share of monitoring postings rises 7.25% more at Delaware firms.

The increase spans risk, compliance, accounting and audit, and legal roles and is stronger in R&D-intensive and uncertain industries, consistent with greater demand for process information when projects are difficult to evaluate. R&D spending and idiosyncratic risk show positive associations, while capital expenditures do not. These associations are consistent with increased risk-taking following the reform. The monitoring response is weaker with stronger external oversight and larger monitoring staffs. The findings show that changes in executive liability can alter firms' demand for internal monitoring.

Anticipatory Pricing under Climate Transition Risk: Evidence from U.S. Airlines

With Simon Birk and Ariela Caglio

Working Paper

Draft: May 2026.

Do firms raise prices before anticipated climate regulation imposes costs? We use the EPA's 2015 proposed aircraft Endangerment Finding in a route-level difference-in-differences design. One standard deviation of fleet age raises fares by 5-6 percent after the signal.

Team Incentives and Firm Risk

With Ariela Caglio and Francesca Franco

Working Paper

Draft: May 2026.

How do common executive performance metrics shape firms' project choices and risk? In S&P 1500 bonus-scorecard data, fully homogeneous scorecards rise from 62 percent of teams in 2006 to 86 percent in 2022 and predict more R&D, fewer acquisitions, and higher idiosyncratic—but not systematic—volatility.

Fully homogeneous executive teams rise steadily over the sample period, making herding visible before the risk tests.
