Degree of Multinationality and Financial Performance: A Study of U.S.-Based Multinational Corporations

This paper examines the marginal benefits that accrue to U.S.-based multinational corporations through increased international investment. Specifically, the study seeks to determine if increased degrees of multinationality produce additional benefits for multinational firms in terms of excess returns and/or reduced risk. The results indicate that during the period studied, the degree of multinationality did not have a significant influence on the risk and return performance of the sample firms. Thus, the study supports the findings of Qian (1996) and Siegel et al. (1995, 1995A) who report that the advantages enjoyed by multinational corporations may be going away.
