Passively managed index funds now hold over 30% of U.S. equity fund assets; this shift raises fundamental questions about monitoring and governance. We show that, relative to active funds, index funds are less effective monitors: (a) they are less likely to vote against firm management on...

We show that mutual funds compete for climate-conscious investment flows. In April 2018, Morningstar introduced a climate-focused label for mutual funds. The release of the "Low Carbon Designation" induced reactions on both the demand and supply sides of the market. First, investors flocked to...

We show how distributions can be reduced to low-dimensional scenario trees. Applied to intertemporal distributions, the scenarios and their probabilities become time-varying factors. From S&P 500 options, two or three time-varying scenarios suffice to forecast returns, implied variance or...

We develop a theory of arbitrage-free dispersion (AFD) that characterizes the testable restrictions of asset pricing models. AFD measures Jensen's gap in the cumulant generating function of pricing kernels and returns. It implies a wide family of model-free dispersion constraints, which extend...

We study empirically whether short selling deters the incorporation of positive information. We find a sizeable reduction of positive information impounding before earnings announcements for stocks more exposed to short selling. The price pressure from short selling cannot explain this effect....

Oil price changes fail to predict asset returns because they are too noisy. We construct an oil trend factor that filters out noise and provide evidence that it predicts bond risk premia well. This result holds in developed and emerging countries, both in sample and out of sample. Notably, the...

Most regulators grant contingent convertible bonds (CoCos) the status of equity. Theory, however, suggests that CoCos can induce debt overhang, thereby, increasing the cost of issuing equity. First, we theoretically investigate how the extent of this debt overhang varies with bank...

This chapter surveys recent econometric methodologies for inference in large dimensional conditional factor models in finance. Changes in the business cycle and asset characteristics induce time variation in factor loadings and risk premia to be accounted for. The growing trend in the use of...

We find that the degree and dynamics of sovereign bond market integration across 21 developed and 18 emerging countries is significantly heterogeneous. We show that better spanning can significantly enhance market integration through dissipating local risk premiums. Integration of the sovereign...

Poor corporate governance permits unreliable financial reporting by a firm's management. The AGR governance rating is based on the premise that a more accurate assessment of the effects of corporate governance can be formulated by taking this output of corporate governance into account in...
