Danish ready-mixed concrete is produced in regional oligopolies. Firms rely on price discrimination through secret discounts. The antitrust authority interprets this as lack of competition and has decided to activate its chief weapon against dormant competition: To make the market more...

This paper provides experimental evidence on exit behavior of asymmetrically sized firms in a duopoly with declining demand. We conduct three treatments: (a) The basic model with indivisible real capital. The structure of this treatment represents the main findings of Ghemawat and Nalebuff...

This paper analyzes a model of capacity choice followed by price competition under demand uncertainty. Under various assumptions regarding the nature and timing of demand realizations, we obtain general predictions concerning the role of demand uncertainty on equilibrium outcomes. We show that...

This Paper introduces a simple extensive form pricing game. The Bertrand outcome is a Nash equilibrium outcome in this game, but it is not necessarily subgame perfect. The subgame perfect equilibrium outcome features the following comparative static properties. The more similar firms are, the...

In view of the uncertainty over the ability of merging firms to achieve efficiency gains, we model the post-merger situation as a Cournot oligopoly wherein the outsiders face uncertainty about the merged entity’s final cost. At the Bayesian equilibrium, a bilateral merger is profitable...

We derive a measure of firm speed of price adjustment that is directly inversely related to market power and compare this to the measure derived by Martin (1993). However, both measures are incorrect when firms have non-zero price conjectural variations and treat competing price levels as...

This study examines spatial variation in the price and accessibility of fast food across a major urban area. We use novel data on the price of a representative fast-food meal and the location of fast-food restaurants belonging to one of three major chains in the District of Columbia and its...

This article develops a model, based on switching costs and technological uncertainty, which explains some aspects of the price dynamics of e-commerce. Switching costs and intertemporal cost correlation lock-in consumers. Firms initially charge low prices to build a customer base. If firms fail...

The paper studies how does the size of a cartel affect the possibility that its members can sustain a collusive agreement. I obtain that collusion is easier to sustain the larger the cartel is. Then, I explore the implications of this result on the incentives of firms to participate in a cartel....
