This work is divided into two complementary parts. In the first part, we develop a partial equilibrium model, through which it is possible to analyze the influence of tariff modicity and the illegal occupation of poles on four agents: energy distributors, telecommunications operators, and energy...

This paper analyses whether scale economies exists in the UK telecommunications industry. The approach employed differs from other UK studies in that panel data for a range of companies is used. This increases the number of observations and thus allows potentially for more robust tests for...

In this paper, we examine welfare implications of switching from a neutrality regime to a network management regime. While in the former a network provider or an integrated ISP should transmit data with a-bit-is-a-bit principle, in the latter it is allowed to differentiate its connection quality...

The internet giants - Facebook, Amazon, Netflix and Google, among others - have transformed society with both positive and negative effects. The negative effects have been stark. There have been huge disruptions caused by e-commerce. More recently, subtler, but even more serious negative effects...

Robert Bork's Antitrust Paradox (1978) has been justification for lack of antitrust behavior for over four decades. His test essentially asks if consumers are harmed by the pricing practices of the firm in the market in which they purchase the good or service. Even if these firms are monopoly or...

For quite a long time, network industries used to be regarded as (natural) monopolies. This was due to these industries having some special characteristics. Network externalities and economies of scale in particular justified the (natural) monopoly thesis. Recently, however, a trend towards...

We examine welfare effects of real-time pricing in electricity markets. Before stochastic energy demand is known, competitive retailers contract with final consumers who exogenously do not have real-time meters. After demand is realized, two electricity generators compete in a uniform price...

Since 1979, when the first antidumping case against China was initiated by the European Union, the EU has lodged nearly 90 antidumping proceedings against China by the end of 2000. China by now, has become the country most accused of dumping by the EU. Most of the antidumping suits have led to...

We consider market dynamics in a reduced form model. In the simplest version, there are two investors and several small noninvesting firms. In each period, one investor can acquire a small firm, the other investor decides about market entry. After that all firms play an oligopoly game. We derive...

The paper calculates the concentration in 6 major routes of the Greek ferry system (2001-2010), important not only for international tourism, including Cruises, but also for the cohesion of the Greek space with EU. Worth noting is the consolidation of companies that took place, where from 25...
