WORKING PAPERS 

Mutual Fund Trading, Greenwashing, and ESG Clientele" (with Yrjo Koskinen and Raffaele Santioni). First version (with slightly different title) August 2021. Online appendix. Revise and Resubmit at Journal of Financial and Quantitative Analysis.

Best Paper Award, Portuguese Finance Network Conference, Funchal, Madeira, July 2023.

This paper provides evidence consistent with ESG mutual funds' discretionary trading being partly responsible for the soft landing of ESG stocks in a market downturn.  


Price elasticity of demand and risk-bearing capacity in sovereign bond auctions” (with José Miguel Cardoso-Costa and José Afonso Faias). First version March 2022. Online appendix. Forthcoming at Review of Financial Studies.

BME Award 2022 to the best paper on Fixed Income Markets at the XXIX Finance Forum of the Spanish Finance Association.

This paper studies prime dealers' bidding in auctions of sovereign bonds to infer their risk-bearing capacity, an important metric for aggregate risk.


How large is the pay premium from executive incentive compensation?" (with Ana Albuquerque, Mary Ellen Carter, and Qi (Flora) Dong). This version April 2023. (online appendix) Forthcoming at The Accounting Review.

Using detailed compensation data from Incentive Lab and simulation analysis, we estimate a risk premium from pay at risk that represents 15% of total pay. The premium correlates positively with proxies for CEO risk aversion. Our estimates of the pay premium can serve as a benchmark to compensation consultants.


Market Timing, Farmer Expectations, and Liquidity Constraints" (with Bruno de Araújo, Luis Marques, Geravásia Mosse, Pippy de Vletter, and Helder Zavale). First version May 2021. (online appendix) Forthcoming at Journal of Development Economics.

This paper connects farmer expectations of produce prices to storage decisions in a context where the farmer is liquidity constrained. The evidence is consistent with the hypothesis that farmers sell right after the harvest season at low prices, knowing that prices will be higher in the future, due to the presence of liquidity constraints. (Link to paper with detailed survey information. Link to NCBA CLUSA paper based on our research.)


Strategic Corporate Purpose" (with Luís Cabral). First version September 2021.  (Paper first circulated under the title "Strategic Leadership in Corporate Social Responsibility".) Revise and Resubmit at Journal of Economics and Management Strategy.

In an industry-equilibrium model, we provide a rationale for firms to become CSR leaders. CSR solves a coordination problem by an appropriate change of the firm's objective function.


Liquidity Provision in the Secondary Market for Private Equity Fund Stakes" (with Johan Cassel, Ludovic Phalippou, and Enrique Schroth). First version May 2018.

This paper finds that asset owners (e.g., pension funds, endowments, banks), not funds specialized in the secondary market (i.e., secondary funds), provide liquidity in times of aggregate liquidity shortages, and that younger and smaller funds are the most exposed to shortages of liquidity. 


Skewness in Stock Returns, Periodic Cash Payouts, and Investor Heterogeneity,” March 2010. First version: November 2009.

Models the effect of firm announcements on conditional heteroskedasticity and trading volume.


Corporate Governance and Asset Prices in a Two-Country Model,” (with Neng Wang) July 2004.

Provides a model to explain the evidence in Jonson, Boone, Breach and Friedman (2000, JFE) who show that during the East Asian crisis, countries with better investor protection went through a lower depreciation of their currency’s exchange rate relative to the U.S. dollar.


PUBLISHED ARTICLES 

29. "Value Creation in Shareholder Activism," (with Vyacheslav Fos and Enrique Schroth). (Previously circulated with the title "Value Creation in Shareholder Activism: A Structural Approach") Journal of Financial Economics 145, pp. 153-178, 2022.  

Journal of Financial Economics Editor’s Choice.

This paper decomposes average Schedule 13D filing announcement returns into value creation (74.8%), stock picking (13.4%), and selection (11.8%) components. Higher value creation predicts improvements in firm performance and lower proxy contest probabilities, whereas abnormal announcements returns do not, suggesting that our estimate identifies more effective activism campaigns. Online appendix.


28. "The Price Effects of Liquidity Shocks: A Study of SEC’s Tick-Size Experiment," (with Shiyun Song and Chen Yao) Journal of Financial Economics 138, pp. 700-724, 2020. Online appendix.

This paper provides causal evidence of the impact of the tick size on stock prices. We document a large liquidity premium. We believe we are the first to offer such evidence in a long literature! We benefit from a unique field experiment conducted by the SEC.


27. "Resiliency of environmental and social stocks: an analysis of the exogenous COVID- 19 market crash" (with Yrjo Koskinen, Shuai Yang, and Chendi Zhang) (Appeared as working paper in the COVID Economics issue 11, CEPR Press. Originally with the title: "Love in the Time of COVID-19: The Resiliency of Environmental and Social Stocks") The Review of Corporate Finance Studies 9, pp. 593–621, 2020.

We present evidence that stocks with high ES ratings have significantly higher returns and lower return volatilities than other stocks. Firms with high ES ratings and high advertising expenditures perform especially well during the crash. This paper highlights the importance of ES policies in making firms more resilient during a time of crisis. Online appendix.


26. "Citizens United v. FEC and Corporate Political Activism," (with Zicheng Lei, Jörg Rocholl, and Chendi Zhang) Journal of Corporate Finance 60, February 2020. Online Appendix

Analyzes the response of politically active firms to the U.S. Supreme Court decision on Citizens United v. FEC. We estimate that the value of a political connection decreases by $6.9 million after Citizens United. Our evidence supports the hypothesis that independent political spending crowds out political connections.


25. "Incentive Pay and Systemic Risk," (with Luis Cabral and Jose Guedes). Review of Financial Studies 32, 4304–4342, 2019

Shows that the presence of relative performance evaluation in compensation contracts and of correlated projects creates systemic risk. Caps on incentive pay and on total pay are not ineffective in reducing systemic risk.
