Competition among the big and the small

Competition among the big and the small Many industries are made up of a few big firms, which are able to manipulate the market outcome, and of a host of small businesses, each of which has a negligible impact on the market. We provide a general equilibrium framework that encapsulates both market structures. Due to the higher toughness of competition, the entry of big firms leads them to sell more through a market expansion effect generated by the shrinking of the monopolistically competitive fringe. Furthermore, social welfare increases with the number of big firms because the procompetitive effect associated with entry dominates the resulting decrease in product diversity. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png The Rand Journal of Economics Wiley

Abstract

Many industries are made up of a few big firms, which are able to manipulate the market outcome, and of a host of small businesses, each of which has a negligible impact on the market. We provide a general equilibrium framework that encapsulates both market structures. Due to the higher toughness of competition, the entry of big firms leads them to sell more through a market expansion effect generated by the shrinking of the monopolistically competitive fringe. Furthermore, social welfare increases with the number of big firms because the procompetitive effect associated with entry dominates the resulting decrease in product diversity.
