Using an aggregative games approach, we analyze horizontal mergers in a model of multiproduct-firm price competition …

Oligopoly models of short-run price competition predict that large firms can exercise market power and generate …

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 … network flows in a communication network or of traffic in a transportation network. We show that increasing competition among …

We study dynamic price competition between sellers offering differentiated products with limited capacity and a common …

(QHFT) model, we classify export goods (at the HS 6-digit level of disaggregation) by quality and price competition. We find … a high proportions of quality-competition goods for the major EU countries and lower proportions for Canada, Australia … and China. However, the overlap of these quality-competition goods is not large, which suggests that characteristics of …
