In this paper we study the problem of long-term capacity adequacy in electricity markets. We implement a dynamic model in which operators compete for investment and electricity production under imperfect Cournot competition. The main aim of this work is to compare three investment incentive...

The effects of a new firm's entry into the telecom service market are examined further. These consist of up- and downstream markets, corresponding to the first and second stages in game theory. When a new entrant can succeed in process innovation and lower production cost, entry of the entrant...

This paper evaluates four publicly discussed policy options to mitigate market power in the German wholesale electricity market. These four options are: a regulatory solution favoured by the Federal Ministry for Economics and Technology, the implementation of a day-ahead flow-based market...

This paper studies competition in data-driven markets, that is, markets where the cost of quality production is decreasing in the amount of machine-generated data about user preferences or characteristics, which is an inseparable byproduct of using services offered in such markets. This gives...

Am 26. Februar 2007 hat die EU-Kommission ein beschleunigtes Vertragsverletzungsverfahren gegen Deutschland wegen der Einführung von angeblichen "Regulierungsferien" in dem jüngst novellierten Telekommunikationsgesetz (TKG) eröffnet. Die Kommission vermutet, dass die dort getroffene...

Die europäischen Postmärkte sollen bis spätestens Ende 2012 vollständig liberalisiert werden. Im Zuge dieser Entwicklung werden derzeit die nationalen Regulierungsrahmen den neuen Bedingungen angepasst, und es wird diskutiert, inwiefern die bisherigen Monopolanbieter (auch) zukünftig ihren...

In a duopoly industry with environmentally differentiated products, we examine the effects of introducing a mandatory environmental quality standard on firms’ environmental quality choices, profits, and the average environmental quality offered by the industry. We show that at low standard...

We consider a duopolistic industry in which pollution is a by-product of production and firms are given emission permits that they can trade. The common wisdom is that allowing for trade in emission permits promotes efficiency. We demonstrate that this common wisdom cannot automatically be...

In the framework of a vertically differentiated mixed duopoly, with uncovered market and costless quality choice, we study the existence of a price equilibrium when a welfare-maximizing public firm producing low quality goods competes against a profit-maximizing private firm producing high...

Shaked and Sutton (1982) and Gelman and Salop (1983) are best remembered for their neat conclusions: a limited quality or limited capacity is an effective tool to relax competition and facilitate entry in a market. We aim at comparing the respective merits of these two strategic commitments. We...
