R&D expenditures and implied equity risk premiums

This study investigates the relationship between research and development (R&D) expenditures and risk premiums implied in the costs of equity capital. We posit that R&D expenditures represent an information risk factor resulting from both information asymmetry about R&D between investors and managers and low-quality R&D reporting that impairs the coordination between investors and managers with respect to managers’ investment decisions. Our results support our position by showing a positive association between R&D expenditures and implied equity risk premiums. From this research along with prior studies, investors can have better knowledge about the risky nature of R&D expenditures that drive up implied risk premiums and at the same time provide opportunities to earn excess returns in a short to long horizon. Accounting standard setters can benefit from this study’s findings that R&D expenditures represent an off-balance-sheet risk factor and thus warrant reconsidering SFAS No. 2 for potential capitalization of R&D expenditures. © 2013, Springer Science+Business Media New York.
