Costs of equity for individual firms are estimated in a Bayesian framework using several factor-based pricing models.

Evidence of structural breaks in the historical return distribution raises concerns about averaging a long series to estimate the current equity premium. Data before a break are relevant if one believes that large shifts in the premium are unlikely or that the premium is associated, to some...

Costs of equity for individual firms are estimated in a Bayesian analysis framework using several factor-based pricing models. Substantial prior uncertainty about mispricing often produces an estimated cost of equity close to that obtained with mispricing precluded, even for a stock whoses...

Equity costs of capital for individual firms are estimated using several models that relate expected returns to betas on one or more pervasive factors. A Bayesian approach incorporates prior uncertainty about an asset's mispricing as well as uncertainty about betas and factor means. Substantial...

This study explores multivariate methods for investment analysis based on a sample of return histories that differ in length across assets. The longer histories provide greater information about moments of returns, not only for the longer-history assets, but for the shorter-history assets as well.
