Özet: This study aims to define an alternative index to measure market power and concentration ratio, similar to the Herfindahl Index and the Dominance Index in terms of ease, as a simple and scalable but more consistent scalar number carrying all the desired properties from such an index, which should be negatively correlated with the number of firms and positively correlated with the variance of firm market shares. In addition to examples from the US industries, based on the alternative index, we also formulate the impact of market concentration on welfare. The impact of technological progress and demand elasticity on market power however is not addressed in this study.
