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,...

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 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.

This paper studies the question of whether and how an employee innovator should commercialize an innovation, when doing so within the firm is less costly than pursuing an outside venture, but risks expropriation by the firm. We show that a weaker chance of expropriation, interpreted as the...

This paper extends the Hall-Roeger methodology in order to investigate the market structure and to measure the degree of market power in the Greek food and beverages manufacturing industry over the period 1984–2007 at the three-digit SIC level. The present paper also estimates the net and...

We investigate the dynamic relationship between advertising and product quality under duopolistic competition. By using a simplified vertical product differentiation model with voluntary advertising, we show that the firm with larger market share has a larger advertising share and that there is...

In this paper, we discuss a scenario in capital structure where two divisional managers compete for capital from a firm for their projects in a perfect information setting. We consider verifiable profits and study take-it-or-leave-it contracts where the managers ask for capital from the firm...

This paper analyzes mergers incentives in an asymmetric mixed oligopoly consisting of two identical private firms and one public firm. It is shown that when there is a technological gap between the public and private firms, both of them will want to merge when the public firm is inefficient and...
