Companies and capitals may face different variants of European markets, being necessary to classify these markets by establishing their importance within the whole strategy of the company. Another goal is the wish to cover as many of these markets as possible under maximum efficiency conditions...

A recent literature has provided empirical evidence that markups are increasing and are heterogeneous across firms. In standard monopolistic competition models, such heterogeneity implies inefficiency even in the presence of free entry. We enrich the standard model of monopolistic competition...

We model the main arguments of the net neutrality debate in a two-sided market framework with network congestion sensitive content providers and Internet consumers on each side, respectively. The platform is controlled by a monopolistic Internet service provider, who may choose to sell content...

We consider a two-sided market model with a monopolistic Internet Service Provider (ISP), network congestion sensitive content providers (CPs), and Internet customers in order to study the impact of Quality-of-Service (QoS) tiering on service innovation, broadband investments, and welfare in...

We examine optimal price ceilings when the regulator is uncertain about demand and supply conditions and maximizes expected consumer surplus. We consider both a perfectly competitive benchmark and imperfectly competitive settings where symmetric firms compete in supply functions. Our analysis...
