Using the simple model of Comanor and Frech (1985), I show that vertical mergers and exclusive dealing contracts are not behaviorally equivalent.

Einkaufen in Internet, die Nutzung von sozialen Netzen oder Online- Banking gehören zum Alltag der Verbraucher in Deutschland. Das Thema Privatsphäre und Datenmissbrauch ist deshalb nahezu täglich in den Medien. Da ist es erstaunlich, dass fundiertes wissenschaftliches Wissen, wie Verbraucher...

This paper develops a simple model of competition among interconnected networks. Access fees are determined either by a regulator or by competition. We show that the price is higher when they compete in both access prices and final tariffs non-cooperatively than when the access fees are...

This (revised) study seeks to examine the rise, expansion, and ultimate decline of the Italian wool-based textile industries over a period of six centuries (from ca. 1100 to ca. 1730). An international trade model combining transaction costs and comparative advantage is employed to explain the...

This paper provides a comprehensive econometric framework for the empirical analysis of countervailing power. It encompasses the two main features of pricing schemes in business-to-business relationships: nonlinear price schedules and bargaining over rents. Disentangling them is critical to the...

We analyze an equilibrium choice of a product quality within a supply chain consisting of a manufacturer and a supplier. A quality of an intermediate good is private information of the supplier and determines the quality of a final product. The manufacturer holds all bargaining power and...

We analyse the effects of input price discrimination in the canonical model where an upstream monopolist sells to downstream firms with various degrees of efficiency. We first recast a series of existing results within our setting, extending previous findings related to discrimination in...
