Project valuation and investment decisions: CAPM versus arbitrage

Magni, Carlo Alberto (2007): Project valuation and investment decisions: CAPM versus arbitrage. Published in: Applied Financial Economics Letters , Vol. 3, No. 1 (March 2007): pp. 137-140.

Abstract

This paper shows that (i) project valuation via disequilibrium NPV+CAPM contradicts valuation via arbitrage pricing, (ii) standard CAPM-minded decision makers may fail to profit from arbitrage opportunities, (iii) standard CAPM-based valuation violates value additivity. As a consequence, the standard use of CAPM for project valuation and decision making should be reconsidered.
