In the framework of symmetric Cournot oligopoly, this paper provides two minimal sets of assumptions on the demand and cost functions that imply respectively that, as the number of firms increases, the minimal and maximal equilibria lead to (i) decreasing industry price and increasing or...

We consider the issue of first versus second mover advantage in differentiated-product Bertrand duopoly with asymmetric linear costs. We provide a generalization of some well-known results in the cases where prices are strategic substitutes or complements, dispensing with extraneous assumptions...
