We study the efficiency of oligopoly equilibria in a model where firms compete over capacities and prices. The … demands across the firms. We first establish the existence of pure strategy subgame perfect equilibria (oligopoly equilibria … oligopoly equilibria of this game can be arbitrarily low. However, if the best oligopoly equilibrium is selected (among multiple …

We study the efficiency of oligopoly equilibria in congested markets. The motivating examples are the allocation of …

We study the efficiency properties of oligopoly equilibria in congested networks. Our measure of efficiency is the … oligopoly equilibria can be bounded by 1/2, where strong oligopoly equilibria are equilibria in which each provider plays a … strict best response and all of the traffic is transmitted. However, even with strong oligopoly equilibria, inefficiency can …
