Equilibrium downstream mark-up and upstream free entry

Ioannis Pinopoulos

Discussion Paper Series from Department of Economics, University of Macedonia

Abstract: We consider a successive Cournot oligopoly model where firms freely enter into the upstream market. We show that, under specific conditions, a higher number of downstream firms can lead to a higher mark-up in the downstream market. Although downstream market power may increase, consumer prices still decrease with the number of downstream firms implying that higher market power does not necessarily imply lower consumer surplus.
