In this paper we first introduce an approach relying on market games to examine how successive oligopolies operate between downstream and upstream markets. This approach is then compared with the traditional analysis of oligopolistic interaction in successive markets. The market outcomes resulting from the two approaches are analysed under di¤erent technological regimes, decreasing vs constant returns.
