I am the Mitsui Life Research Fellow at the Ross School of Business at the University of Michigan, Ann Arbor. This fall, I will join WU Vienna as Assistant Professor of Finance (tenure track).

My research interests are in theoretically founded empirical Asset Pricing.

I document a new stylized fact: the higher the share of institutional ownership in a stock, the more its price-dividend ratio is driven by expected return variation rather than by changes in dividend growth expectations. As a general equilibrium outcome, expected return variation (i.e. return predictability) crucially depends on investor properties. Strongly time-varying volatility in the marginal utility of institutional managers as marginal investors in stocks with high institutional ownership provides a natural explanation for the result. In a general equilibrium model, imperfectly shared time-varying redemption risk generates the observed predictability patterns among a priori identical stocks. My findings help explain the weak return predictability of small and value stocks and the postwar predictability reversal.

We introduce Implied Volatility Duration (IVD) as a new measure for the timing of uncertainty resolution, with a high IVD corresponding to late resolution. Portfolio sorts on a large cross-section of stocks indicate that investors demand on average about seven percent return per year as a compensation for a late resolution of uncertainty. In a general equilibrium model, we show that `late' stocks can only have higher expected returns than `early' stocks, if the investor exhibits a preference for early resolution of uncertainty. Our empirical analysis thus provides a purely market-based assessment of the timing preferences of the marginal investor.

I test the hypothesis that the differences in return predictability between the value and growth portfolios are indeed due to value stocks having shorter cash flow duration. I find that duration acts as amplification for the change in dividend yields that is caused by discount rate variation. However, differences in return predictability across book-to-market sorted portfolios go beyond the effect of duration. For comparable cash flow duration, discount rate variation explains about 40% more of the dividend yield variation for growth stocks as opposed to value stocks. This is consistent with recent research suggesting that the exposure to value-specific risks is not driven by duration.
