In August 2020, I joined the Frankfurt School of Finance & Management as an Assistant Professor of Finance. I obtained PhD in Finance from the Swiss Finance Institute (SFI) and École Polytechnique Fédérale de Lausanne (EPFL). My research interests lie in empirical corporate finance and corporate governance.

Why Are Firms With More Managerial Ownership Worth Less?
→FORTHCOMING IN THE JOURNAL OF FINANCIAL ECONOMICS

with Rüdiger Fahlenbrach, René M. Stulz, and Jérôme Taillard

Using more than 50,000 firm-years from 1988 to 2015, we show that the empirical relation between a firm’s Tobin’s q and managerial ownership is systematically negative. When we restrict our sample to larger firms as in the prior literature, our findings are consistent with the literature, showing that there is an increasing and concave relation between q and managerial ownership. We show that these seemingly contradictory results are explained by cumulative past performance and liquidity. Better performing firms have more liquid equity, which enables insiders to more easily sell shares after the IPO, and they also have a higher Tobin’s q.

Rewriting History II: The (Un)Predictable Past of ESG Ratings
[October 2020]

with Florian Berg and Zacharias Sautner

The explosion in ESG research has led to a strong reliance on ESG rating providers. We document widespread changes to the historical ratings of Refinitiv ESG, formerly ASSET4, a key rating provider. Across two downloads in 2018 and 2020, we document large rewritings in ESG ratings, which are systematic and partially related to firm characteristics. The retrospective rating changes have important implications for researchers and investment professionals. Depending on whether the original or rewritten data are used, rankings and classifications of firms into ESG quantiles change. We demonstrate that these changes affect tests that relate ESG ratings to stock returns.

Why Do U.S. CEOs Pledge Their Own Company's Stock?
[March 2019]

Solo-authored

This paper presents the first large-scale empirical analysis of the pledging phenomenon among U.S. CEOs. Between 2007 and 2016, 7.6% of publicly listed U.S. firms disclosed that their CEOs had pledged company stock as collateral for a loan. On average, CEOs pledge 38% of their shares. The mean loan value is an economically sizeable $65 million. CEOs use the funds to either double down (6.0%), hedge their ownership (3.5%), or to obtain liquidity while maintaining ownership (90.5%). My event study results reveal that stock market participants view pledging as value-enhancing, but perceive significant pledging as value-destroying. Similarly, I find no evidence of its negative shareholder value consequences, except for CEOs who engage in significant pledging.
