To extend the empirical research on Gibrat's law in developing countries, this article uses a linear-in-means model to test how inter-firm interactions can affect the growth of small manufacturing firms in Tunisia. More specifically, we distinguish between the effects of own firm's...

This paper investigates the optimal partial privatization of a Stackelberg leader in a mixed oligopoly. It builds from Matsumura's duopoly Cournot model (1998) by comparing Cournot and Stackelberg models. In Cournot, partial ownership is optimal in a duopoly. In Stackelberg, partial...

We analyze Varian's (1980) Model of Sales, and show that when the number of uninformed consumers increases, prices become less competitive for all consumers. Thus, the influx of uninformed consumers generates a negative externality increasing prices paid by informed consumers.

This paper considers a spatial discrimination Cournot model with asymmetric demand. We use the geographical interpretation of the linear market and introduce differentiated products. We analyze a location-quantity game and show that agglomeration or dispersed locations may arise, depending on...

This paper develops a spatial model to analyze the stability of a market sharing agreement between two firms. We find that the stability of the cartel depends on the relative market size of each firm. Collusion is not attractive for firms with a small home market, but the incentive for collusion...

We discuss the effects of bundling two goods offered by two symmetric firms. This situation requires the use of some sharing rule for the profits from the sales of the bundle. We show that the choice of this rule may have substantial effects on prices and profits – even if the possible...

This paper develops a methodology to uncover consumer preferences from a discrete-choice demand model of product differentiation using plant-level data. When prices and quantities are observed, the appropriate strategy for estimating such model is well developed. However, most plant-level data...

In a mixed oligopoly, when the public leader becomes a private leader and the government provides output subsidies, then privatization causes the optimal subsidy, profits and welfare to fall [Economics Letters 83 (2004) 411]. We show instead that if the leader and the followers receive...

This note analyzes the repeated interaction among buyers of a homogeneous good, in a setting of imperfect buyer mobility. The buyers are assumed to play a dynamic game of imperfect information: at each stage every buyer chooses which seller to visit without knowing the current and past choices...
