The impact of geographic diversification on firm performance

This paper empirically examines the economic effects of both corporate industrial and geographic diversifications. Using a sample of 28,050 firm-year observations from 1990 to 1998, we find that industrial and geographic diversifications are associated with firm value decrease. Consistent with Denis et al. [Denis, D. J., Denis, D. K., and Yost, K. (2002). Global diversification, industrial diversification, and firm value. Journal of Finance, 57, 1951-1979], the costs of corporate diversification may outweigh the benefits of diversification. We find that geographically diversified firms have higher R&D expenditures, advertising expenses, operating income, ROE and ROA than industrially diversified firms. In addition, higher R&D expenditures create value for multi-segment global firms, but not for single-segment global firms. This result implies that there exists an interaction effect between industrial and geographic diversification. We also examine the effects of agency cost issues, as characterized by the diversification discount, on both industrial and geographic diversification. Consistent with the agency explanation, firms with high equity-based compensation are associated with higher firm value than firms with low equity-based compensation. Also, we find that firms with a higher insider ownership percentage are associated with higher excess value.
