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...

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...

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.

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...

The impact of input price changes on industry concentration in a Cournot oligopoly depends on the type of firm heterogeneity and on the curvature of the demand function. Firms might be heterogeneous in their ability to use the input undergoing the price change, or in their ability to use...

This paper explores the asymmetric adjustment speed of gasoline price in twelve European Union (EU) countries transmitted directly in a single stage formulation. The empirical results shed new light on the taxation effect and its role to the price asymmetry nexus, pointing that in many EU...

This note analyzes the impact of indirect network effects in emerging two-sided markets on prices, quantities, profits and market entry assuming market enlargement induced by indirect network effects. Only if indirect network effects are small, the conventional results of market entry apply,...

We consider a two-stage location-price Hotelling model where the consumers can only buy from one direction, as presented by Kharbach (2009, Economics Bulletin). We show that the equilibrium outcome derived by Kharbach does not constitute a subgame perfect Nash equilibrium.
