Research Notes and Commentaries toward a General Theory of Competitive Dominance: Comments and Extensions On
نویسندگان
چکیده
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.

The main question of this research is, can the tradi...
متن کاملA History of Selected Topics in Categorical Algebra I: From Galois Theory to Abstract Commutators and Internal Groupoids
This paper is a chronological survey, with no proofs, of a direction in categorical algebra, which is based on categorical Galois theory and involves generalized central extensions, commutators, and internal groupoids in Barr exact Mal’tsev and more general categories. Galois theory proposes a notion of central extension, and motivates the study of internal groupoids, which is then used as an a...
