Horizontal Mergers Without Synergies May Increase Consumer Welfare


  • Stennek, Johan

    () (The Research Institute of Industrial Economics)


Markets with imperfect competition do not induce a cost-minimizing allocation of production between firms. The market's ability to rationalize production is even more limited if costs are private information to firms. Merger in such markets generate an efficiency gain associated with the pooling of information. Not only may costs be reduced, the price level and price variability may also decline and consumers may thus gain.
