Risk-Factor Disclosure and Asset Prices

While researchers and practitioners alike estimate firms' exposures to systematic risk factors, the disclosure literature typically assumes that exposures are common knowledge. We develop a model where the firm's exposure to a factor is unknown, and analyze the effect of factor-exposure uncertainty on share price and disclosure about the exposure. We find that: (i) factor-exposure uncertainty introduces skewness and excess kurtosis in the cash-flow distribution relative to the commonly used normal distribution; (ii) risk--factor disclosure affects all moments of that distribution; and (iii) the pricing of higher moments affects the price response of disclosure and the incentives to disclose. For example, factor-exposure uncertainty may actually increase price when the uncertainty implies positive skewness in the cash flow distribution. Hence, a reduction in uncertainty through disclosure may increase cost of capital. We also extend our model to multiple firms and show that factor-exposure uncertainty manifests as uncertainty about a firm's CAPM beta.
