We investigate the association between voluntary disclosure and the risk-related discount investors apply to price. First, we study the association between (endogenous) disclosure choice and the discount in price induced by changes in the underlying model parameters: this informs empirical research that ignores endogeneity of disclosure by, for example, omitting the exogenous determinants of disclosure and the discount in price from the regressions employed. Second, we investigate the incremental effect of disclosure on the discount in price: this informs empirical research that controls for the direct effect of exogenous factors on the discount in price by, for example, including the exogenous variables in regression models employed. Finally, we examine the incremental effect of disclosure on the discount in price when changes in disclosure are not induced by changes in underlying exogenous parameters: this further informs empirical research that controls for the effect of exogenous factors on both the discount in price and disclosure, and focuses on the association between 'unexplained disclosure' and the discount.
AbstractWe investigate the association between voluntary disclosure and the risk-related discount investors apply to price. Prior research indicates that when the analysis is based on a commitment to disclose the association is negative (i.e., more disclosure is associated with a lower discount). Our results suggest that with voluntary, or endogenous, disclosure the association is not necessarily negative, and in most cases the association is positive. This implies that in studies of either the discount or cost of capital, some care should be taken to distinguish endogenous disclosure choice (i.e., voluntary disclosure) from disclosure commitment.JEL classification: G12, G14, G31, M41
