Abstract: When a firm invests in a new project, the risk of the project maybe higher than the current average risk level of the company. Therefore, adopting what kind of discount rate in evaluating a new project will be the key of whether or not to proceed with the project. The most recent studies on the combination of MM theory and CAPM model are based on the formula of cost of capital, which could get a beta equation of levered firm and unlevered firm. However, when we treat a company as an asset portfolio, the risk factor of the asset is the weighted average risk of equity and debt. From the definition of debt risk in MM theory, we also can get beta equation. It’s worthwhile to apply the combination of CAPM model and MM theory into the investment evaluations.

Key words: MM theory, CAPM model, project assessment, discount rate.

When a firm decides to invest a new project, how to determine discount rate becomes the most important factor. Usually firms adopt different discount rates to the different investment projects. However, how to determine specific discount rate is a critical decision. This paper will combine MM theory with CAPM model, to study how a firm determines appropriate discount rate when they...
