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.

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: New paper, When Is (Performance-Sensitive) Debt Optimal? Existing theories of debt assume output is the only contractible performance measure available.
