31. The End of ESG
Financial Management, 52(1), 3-17, Spring 2023 (lead article)
SSRN Top 3 download, across all SSRN journals, Sept-Nov 2022
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.

Journal of Accounting Research, 60(3), 1007-1046, June 2022
Investor Responsibility Research Center (IRRC) Institute Research Award, 2017

26. How Should Performance Signals Affect Contracts? (with Pierre Chaigneau and Daniel Gottlieb) (web appendix)
Review of Financial Studies, 35(1), 168-206, January 2022
The informativeness principle demonstrates that a contract should depend on informative signals. This paper studies how they should do so. “Good” signals of performance need not increase pay; for performance-based vesting, performance measures should affect the strike price rather than the number of vesting options.

25. Governance Under Common Ownership (with Doron Levit and Devin Reilly) (web appendix)
Review of Financial Studies, 32(7), 2673-2719, July 2019
Common ownership gives investors flexibility of what to sell upon a liquidity shock. Thus, their trades are driven more by information and less by liquidity needs, increasing price informativeness.

24. Financing Through Asset Sales (with William Mann) (web appendix)
Management Science, 65(7), 3043-3060, July 2019
Analyzes choice between asset sales and equity issuance as financing channels. Firms need not issue the claim with lowest information asymmetry, in contrast to Myers and Majluf (1984).
Coverage: [email protected], VoxEU, Harvard Law School Corporate Governance Forum

23. The Informativeness Principle Without The First-Order Approach (with Pierre Chaigneau and Daniel Gottlieb) (web appendix)
Games and Economic Behavior, 113, 743-755, January 2019
We show that the informativeness principle does not hold if the first-order approach is invalid. We derive a “generalized informativeness principle” that holds generically, even if the first-order approach is invalid.

22. Strategic News Releases in Equity Vesting Months (with Luis Goncalves-Pinto, Moqi Groen-Xu, and Yanbo Wang) (web appendix)
Review of Financial Studies, 31(11), 4099-4141, November 2018 (lead article)
CEOs strategically time corporate news releases in months in which their equity vests. These releases boost the stock price and liquidity, which the CEO takes advantage of by cashing out shortly after.

Journal of Financial Economics 126(1), 74-96, October 2017
Best Paper Award, German Finance Association, 2016
Managers learn from prices to guide their investment decisions – financial markets matter for the real economy. But value of financial markets depends not on the total amount of information in prices, but where this information comes from.

17. The Real Costs of Financial Efficiency When Some Information is Soft (with Mirko Heinle and Chong Huang)
Review of Finance 20(6), 2151-2182, October 2016
Even if the actual act of disclosure is costless, a high-disclosure policy can be costly. Increased disclosure of “hard” information distorts the relative weighting of “hard” and “soft” information, deterring investment.

16. Feedback Effects, Asymmetric Trading, and the Limits to Arbitrage (with Itay Goldstein and Wei Jiang) (web appendix)
American Economic Review 105(12), 3766-3797, December 2015
Trading impounds information into prices, guiding real decisions and improving firm value. This feedback effect increases (reduces) the profitability of informed buying (selling), creating an asymmetric limit to arbitrage.

15. The Effect of Liquidity on Governance (with Vivian Fang and Emanuel Zur) (web appendix)
Review of Financial Studies 26(6), 1443-1482, June 2013
Stock liquidity increases governance through “exit”/trading and to a lesser extent “voice”/intervention. We use decimalization to identify causal effects.

Journal of Financial Economics 102(1), 81-101, October 2011

8. The Effect of Risk on the CEO Market (with Xavier Gabaix)
Review of Financial Studies 24(8), 2822-2863, August 2011
Risk aversion causes distortions to a standard assignment model – risky firms hire less talented CEOs. Firm size is not a proxy for talent. Pay depends not only on firm size, but also risk and disutility.
