In an oligopoly, prior to choosing quantities/prices, each firm has an opportunity to form pair-wise collaborative links with other firms. These pair-wise links defines a collaboration network. We study stable and efficient networks under different types of market competition. We find that...

This paper estimates a model of retail oligopoly where consumers choose between stores using consumer data which specifies the firm operating the chosen store and not the specific store (as is convenient practice for retail surveys). The location and other characteristics of the stores are...

The endogeneity of equilibrium strategies makes modelling uncertainty about the behaviour of other economic players difficult. Recent developments in decision and game theory offer an opportunity to include strategic uncertainty as an explanatory variable in economic analysis. This paper...

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...

In this paper, the authors consider a European industry characterized by vertical product differentiation. Using a two-stages model with quality choice made before price competition takes place, the authors show that EU antidumping policy that takes the form of price-undertaking offers a...

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...

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...

It has been shown that if buyers have zero search cost and the remainder a common positive search cost, and sellers post prices, then there is a unique symmetric Nash equilibrium-sellers choose a price distribution. We show that increasing the number of search cost types results in another...

A model of an oligopolistic market with a homogeneous product is examined. Each subject of the model uses a conjecture about the market response to variations of its production volume. The conjecture value depends upon both the current total volume of production at the market and the subject's...

We analyse the incidence of ad valorem and unit excise taxes in an oligopolistic industry with diffentiated products and price-setting (Bertrand) firms.
