Assessing Alternative Proxies for the Expected Risk Premium
评估了五种估算公司股权资本成本的方法，发现其中两种（rDIVPREM和rPEGPREM）与风险的关系稳定且可预测，优于其他方法。
Managers, investors, and researchers have a compelling interest in identifying a reliable empirical proxy for firm-specific cost of equity capital (r). In theory, deducing r is possible if the market's future cash flow forecast and current stock price are observable. Practically, deducing r is dependent on the ability to estimate the market's forecasted terminal value. We evaluate five methods of deducing firm-specific r (labeled rDIVPREM, rGLSPREM, rGORPREM, rOJNPREM, and rPEGPREM) that deal with this conundrum differently. The extent to which the estimates are associated with firm risk in a stable and meaningful manner is the basis for our assessment. We find that the rDIVPREM and rPEGPREM estimates are consistently and predictably related to risk, while the alternatives are not. Based on these results, we conclude that rDIVPREM and rPEGPREM dominate the alternatives.
