What Affects the Implied Cost of Equity Capital?

We estimate implied cost of equity capital for a sample of firms from 1984 to 1998 using the Ohlson and Juettner (2000) model that does not make restrictive assumptions about clean surplus and payout policies. We find that cost of equity capital is strongly positively associated with conventional risk factors such as earnings variability, systematic and unsystematic return volatility, and leverage, and is negatively associated with analyst following. These associations are robust to controls for industry membership and to running the regression in changes instead of levels. Our results support the Ohlson-Juettner metric as a robust and appealing measure of cost of equity capital
