We study a discrete time dynamic game of price competition with spatially differentiated products and price adjustment costs. We characterise the Markov perfect and the open-loop equilibrium of our game. We find that in the steady state Markov perfect equilibrium, given the presence of...

In a duopoly industry with environmentally differentiated products, we examine the effects of introducing a mandatory environmental quality standard on firms' environmental quality choices, profits, and the average environmental quality offered by the industry. We show that at low standard...

We develop a product-differentiated model where the product space is a network defined as a set of varieties (nodes) linked by their degrees of substitutability (edges). We also locate consumers into this network, so that the location of each consumer (node) corresponds to her “ideal”...

This paper provides sufficient conditions under which the negotiated wage in unionized oligopolistic industries with centralized negotiations is independent of a number of product market features (such as the number of firms, the degree of product substitutability, or the type of market...

This paper presents a micro-econometric model testing for changes in firms' product and pricing decisions in two American industries where leading companies have sharply increased their financial leverage. According to the latest econometric theory, the empirical analysis is carried out through...

Allowing firms to cooperate in their R&D is an industrial policy, which has received much attention in recent economics literature. Many of these contributions are based on the seminal analysis of d'Aspremont and Jacquemin (1988). We provide a general version of their model, which encompasses...

This paper analyses the problem of price discrimination in a market where consumers have heterogeneous preferences both over a horizontal parameter (brand) and a vertical one (quality). Discriminatory contracts are characterised for different market structures. It is shown that price dispersion,...

This paper shows that as long as the stock market has perfect foresight, some dividends are distributed, and incentives are paid more than once or are deferred, stock-related compensation packages are strong incentives for managers to support tacit collusive agreements in repeated oligopolies....

This paper investigates the structure of bilateral oligopolies - a simple version of Shapley Shubik games with two types of traders and two commodities. It shows that interior equilibria exist, studies the example of CES utility functions to uncover the relation between the complementarity of...
