Industry competitiveness using Herfindahl and entropy concentration indices with firm market capitalization data
Abstract:While previous studies of industry concentration have traditionally utilized sales or market share data, no studies that we are aware of have been done with market capitalization data. If the markets are successful at valuing a firm's current and future prospects, it can be argued that concentration indices and other metrics based on the market value of the firms in an industry should be a good proxy for market power within an industry. This study presents a study of the market concentration using the Herfindahl and entropy concentration indices for 13 industries.
