Abstract: This paper examines the effect of geographic and industrial diversification on firm value for a sample of over 20,000 firm-year observations of U.S. corporations from 1987-1993. Our" multivariate tests indicate the average value of a firm with international operations is 2.2% higher than comparable domestic single activity firms, while the average value of a firm with activities in multiple industrial segments is 5.4% lower than a portfolio of comparable focused domestic firms in similar activities. More importantly, we demonstrate that failure to control simultaneously for both dimensions of diversification results in over-estimation of the negative value impact of industrial diversification, but has little impact on estimates of the positive value impact of geographic diversification.
