摘要: We consider Bertrand oligopoly TU-games with differentiated products. assume that the demand system is Shubik’s and firms operate at a constant identical marginal average cost. Our main results state in \(\alpha \), \(\beta \) \(\gamma \)-characteristic function form satisfy convexity property, meaning there exist strong incentives for large-scale cooperation between on prices.
