The Effect of Horizontal Mergers, When Firms compete in Prices and Investments

By: Massimo MottaEmanuele Tarantino
Abstract: We study the effects of mergers when firms offer differentiated products and compete in prices and investments. Since it is in principle ambiguous, we use aggregative game theory to sign the net effect of the merger: We find that only if it entailed sufficient efficiency gains, could the merger raise total investments and consumer surplus. We also prove there exist classes of models for which the results obtained with cost-reducing investments are equivalent to those with quality-enhancing investments. Finally, we show that, from the consumer welfare point of view, a R&D cooperative agreement is superior to any consumer-welfare reducing merger.
