We examine the properties of equilibrium stock returns in an incomplete information economy in which agents need to learn the hidden state of the endowment process. Both Bayesian and suboptimal learning rules are considered, including near-rational learning, conservatism, representativeness,...

One finding of recent empirical studies is that financially distressed stocks have large dispersion in their book to market value of equity (BM) ratios. In this paper we provide an explanation based entirely on rational decision making by investors. Our main argument is that the likelihood of a...

We develop a dynamic equilibrium model to derive testable time-series and cross-sectional implications for the endogenous relations among ownership concentration, managerial incentives, and asset prices. For a given firm at any date, ownership concentration is positively related to managerial...

It is conventionally perceived in the literature that weak analysts are likely to under weight their private information and strategically bias their announcements in the direction of the public beliefs to avoid scenarios where their private information turns out to be wrong, whereas strong...

It is conventionally perceived in the literature that weak analysts are likely to under-weight their private information and strategically bias their announcements in the direction of the public beliefs to avoid scenarios where their private information turns out to be wrong, whereas strong...

Time-varying leverage driven by common shocks to firm asset returns introduces a factor structure in idiosyncratic equity return volatilities (IVOL). In a standard dynamic capital structure model in which the CAPM holds for asset returns, we show that three factors explain the IVOL...

Actively managed mutual funds exhibit heterogeneous and time-varying returns to fund and industry scale. When a fund starts out, it exhibits increasing returns to scale (IRS) to industry size and decreasing returns to scale (DRS) to fund size. As funds get older and larger, industry size IRS...

We examine the dynamic properties of equilibrium stock returns in an incomplete information economy in which the agents need to learn the hidden state of the endowment process. We consider both the case of optimal Bayesian learning and suboptimal learning, including near-rational learning, over-...
