We analyse optimal pricing and quality of a monopolistic journal and the optimality of open access in a two-sided model. The predominant aspect of the model that determines the quality levels at which open access is optimal is the nature of the relationship between readers and authors in a...

We provide a two-sided model in a vertical di§erentiation context. We solve the model and we calculate the equilibrium in terms of advertising levels, subscription fees and qualities provision, both in duopoly - two platforms of different quality - and in monopoly case. We would like to...

This paper shows in a vertical product differentiation model with variable costs of quality that monopolistic third-degree price discrimination always reduces welfare regardless of whether the quality is fixed or is endogenous. The results provide rich implications for antitrust policy.

Triggered by the concentration process in the electricity and gas markets, the land of Hesse proposes to give the German cartel office power to divest dominant firms or oligopolies if this is necessary to restore competition. The paper shows that the reform would be in line with constitutional...

We consider the role of the endogenous choice of platform quality in a broadcasting duopoly market where competing media platforms choose also their level of advertising. We compare the equilibrium levels of quality, advertising and welfare under private and mixed duopoly competition. We show...

Empirical models of differentiated product demand are widely used by both academics and practitioners. While these methods treat carefully the potential endogeneity of price, until recently they have assumed the number and characteristics of the products offered by firms are exogenous. This...

The NCAA is commonly viewed as a cartel. We model the cartel relationship between the member teams and the NCAA central organization as a principal-agent relationship. Our model predicts imperfect agency behavior on the part of the NCAA with corresponding overregulation relative to the level...

This paper presents a theory of vertically interrelated markets of identical fixed size under implementation of positive indirect network effects. By introducing two Salop circles, a two-sided market model is provided, where intermediaries of differentiated copyrights for intellectual property,...
