Toward a general theory of competitive dominance: comments and extensions on powell (2003)

Deskripsi

In a recent paper, Powell (2003) studied 20-year performance in 21 industries, using an ordinal performance measure ('wins'), and the Gini coefficient as a measure of competitive dominance. The findings suggest that firm performance is statistically indistinguishable from performance in non-business domains such as politics, games, sports, and pageants. This paper extends these findings, developing the statistical foundations for a general theory of competitive dominance. The paper presents a Gibrat-based null hypothesis, develops a decomposable index of competitive dominance, and suggests statistical procedures and empirical methods for future research..Printed Journal
