M Science features many and diverse articles that analyze competitive responsiveness. Although recent Marketing Science editorials (e.g., Shugan 2002) suggest that competitive responsiveness is only a part of a comprehensive competitive marketing strategy, it remains a vital part. For that reason and many others, Marketing Science is particularly proud of this special issue edited by David J. R...

Competitive Responsiveness

Marketing strategy and tactics depend on the firm’s strengths and weaknesses, including marketing activities relative to those of current and potential competitors, and on customer demand. The impact of marketing often depends on how a firm’s own activities compare to those of competitors (Day and Reibstein 1997). For example, a customer’s willingness to pay for a product or service offered by ...

Comments on relaxed $(gamma, r)$-cocoercive mappings

We show that the variational inequality $VI(C,A)$ has aunique solution for a relaxed $(gamma , r)$-cocoercive,$mu$-Lipschitzian mapping $A: Cto H$ with $r>gamma mu^2$, where$C$ is a nonempty closed convex subset of a Hilbert space $H$. Fromthis result, it can be derived that, for example, the recentalgorithms given in the references of this paper, despite theirbecoming more complicated, are not...

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

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, develo...
