Abstract
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.

Notes
The forecasted earnings per share is the mean forecast of earnings per share. We substitute the mean forecast with the median forecast of earnings per share, and we obtain qualitatively similar empirical results.
We also use all available firms with fiscal year end in December and non-December to re-do our analyses. Despite slightly weak relationship among variables, the results using all available firms are qualitatively similar to our reported results. Because firms with fiscal year end in December make up the majority of our sample, we present results based on the firms with fiscal year end in December.
Untabulated descriptive statistics show that our sample covers a wide range of industries based on the Fama and French’s (1997) industry classification.
Using CRSP equally-weighted market index yields the results similar to those employing CRSP value-weighted market index.
After deletion of firms in the financial institution and utility industries, the full sample contains 35,105 observations with 5,834 distinct firms.
