This paper studies whether it is possible to characterize an optimal, time-consistent tariff to protect an infant-industry in the presence of learning effects. A domestic monopolist decides how much to produce, taking into account learning effects induced by its current production, while the...

This paper studies a strategic market game where agents fragment their bids on different markets. Simple conditions for existence of an interior equilibrium point are provided. In equilibrium, all agents are active on the same markets and prices are identical across markets, so that all...

This paper considers a model of oligopolistic competition and locational choice that incorporates the notion of regional industrial systems. Firms play a non cooperative game where the strategy set of firms is given by a set of existing industrial districts. Each firm is distinguished by its...

We study the development of an industry-evolution of capacity, production and prices- in a continuous-time real-options model under various assumptions on competition. Investment takes the form of sequential acquisition of indivisible units of capacity. As benchmarks, we determine the optimal...

This paper considers an investment timing problem in a dipole framework. The results of the seminal contribution by Fudenberg and Tirole (1985, RES) are extended by introduction of uncertainty. Three scenarios are identified. In the first scenario we have a preemption equilibrium with dispersed...

We analyze an oligopoly model where firms choose both quantities and access fees. Per unit prices are determined endogenously to equate quantity demanded with quantity supplied at each firm. In a Nash equilibrium of the game played by firms, the per unit prices equal mairginal cost and access...

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...

This paper investigates the endogenous choice between price- and quantity-setting behaviour in a duopoly game where firms invest in product development first, and then play a marketing game later. Only in the initial R&D stage, the two firms set up a joint venture in order to share the costs of...

In an oligopoly supergame, firms' actions in prices and quantities are subject to non-negativity constraints. These constraints can obstruct the practicability of optimal punishment (a la Abreu (1986), Lambson (1987), and Hackner (1996)) in sustaining tacit collusion. Noting that the prospect of...

We study endogenous coalition formation in contexts where individual (and group) payoffs depend on the entire coalition structure that might form. We capture potential interaction across coalitions by means of a partition function.
