Sept 22: New paper, The End of ESG. ESG is both very important and nothing special. It’s very important for long-term value, and thus relevant for everyone, not just ESG folks. It’s nothing special versus other drivers of value and shouldn’t be put on a pedestal.

April 22: New paper, Socially Responsible Divestment. Blanket exclusion of “brown” industries provides no incentives for brown firms to take corrective actions, as they will be divested regardless. We show that the most effective strategy is often “tilting” – underweighting a brown industry but being willing to hold best-in-class firms.

Spring 22: The Purpose of a Finance Professor published in Financial Management. Based on my keynote speech at the 2021 FMA Annual Meeting.

Jan-Feb 22: When People Listen to Happy Songs, the Market Outperforms. Harvard Business Review magazine “Defend Your Research” interview.

Jan 22: How Should Performance Signals Affect Contracts? published in Review of Financial Studies. The informativeness principle demonstrates that a contract should depend on informative signals. This paper studies how they should do so.

Sept 21: The Long-Term Consequences of Short-Term Incentives forthcoming in Journal of Accounting Research. Vesting equity is associated with a higher likelihood of M&A and share repurchases, and higher short-term returns but lower long-term returns to these actions.

Jul 21: Music Sentiment and Stock Returns Around the World forthcoming in Journal of Financial Economics. We introduces a real-time, continuous measure of national sentiment – the positivity of songs that citizens listen to – and link it to abnormal stock returns (which subsequently reverse), volatility, and mutual fund flows.

Jul 21: New paper, When Is (Performance-Sensitive) Debt Optimal? Existing theories of debt assume output is the only contractible performance measure available. We show that debt continues to be optimal when the firm has access to other performance signals – and how these signals should affect the debt repayment, leading to performance-sensitive debt.

Jun 21: New paper, CEO Compensation: Evidence From the Field. We survey directors and investors on how they set CEO pay in practice, revealing a number of departures from mainstream academic models.
