Abstract
We propose a new measure to assess market dominance. Contrary to concentration measures such as the Herfindahl–Hirschman index that characterizes the concentration of an industry, our dominance measure suggests an approach that classifies when an individual firm has a dominant position. In our measure, the criterion for dominance is relaxed as the intensity of existing competition increases or as entry barriers are lowered. We apply the dominance measure to a number of well-known competition cases.
