Search intensity in oligopoly

Article Abstract:

A price-setting oligopoly game, where the existence of buyers with differing price information is featured, is presented. Aside from having determined the general conditions that result in equilibrium with price dispersion, a revealing reinterpretation of models characterized by less complex information structures is provided. Results revealed that additional price information in the market affects prices differently. Average prices can only decrease after poorly informed buyers have been reached.

Effects of cost changes on oligopolists' profits

Article Abstract:

A study was conducted to examine the effects of cost changes which influence firms in a constant-returns-to-scale Cournot oligopoly. Analysis shows that cost increases may be good for some or even all firms. The effect of such cost variations on firms is conditioned by market share levels, industry cost levels, the number of participating firms in the market and on the demand curve's slope elasticity.
