Duopoly competition can take different forms: Bertrand, Cournot, Bertrand-Stackelberg, Cournot-Stackelberg and joint profit maximization. In comparing these market structures this paper make three contributions. First, we find a clear price (output) ranking among these five markets when goods...

When goods are substitutes (complements), we find a clear price (output) ranking across five duopoly markets, namely Cournot, Bertrand, Cournot-Stackelberg, Bertrand-Stackelberg, and joint profit maximization. We explain these rankings in terms of levels of conjectural variation.

Duopoly competition can take different forms: Bertrand, Cournot, Bertrand-Stackelberg, Cournot-Stackelberg and joint profit maximization. In this paper we find a clear price ranking among these five markets when goods are substitutes and an output ranking when goods are complements. Moreover,...
