1. If a new project has the same risk as the common stock of the firm, what discount rate should the firm use?

2. If a new project has the same risk as the entire firm (debt and equity), what discount rate should the firm use? (Hint: Betas are “additive.” In the present context, this means the following. The value of the firm

(V ) equals the sum of the value of equity (E) and debt (B). That is, the firm is really a portfolio of equity and debt. As a result, the beta of the firm equals the weighted average of the betas of equity and debt, where the weights are given by the ratios of E over V and B over V , respectively.)
