We argue that the empirical evidence against the Capital Asset Pricing Model (CAPM) based on stock returns does not invalidate its use for estimating the cost of capital for projects in making capital budgeting decisions. Since stocks are backed not only by projects in place, but also the...

We demonstrate, using data for the period 1954-2003, that differences in exposure to consumption risk explains cross sectional differences in average excess returns (cost of equity capital) across the 25 benchmark equity portfolios constructed by Fama and French (1993). We use yearly returns on...

To create value, a firm must invest in projects that provide a return greater than the cost of capital. The cost of capital is not observed and its estimation requires assumptions on investors' consumption, savings, and portfolio decisions. We review the academic literature on firms' cost of...

We argue that the CAPM may be a reasonable model for estimating the cost of capital for projects in spite of increasing empirical evidence in the literature against the CAPM based on stock returns. As McDonald and Siegel (1985) and Berk, Green and Naik (1999) point out, stocks are backed by...
