We explore the hypothesis that export policies and trade patterns of national players in the steam coal market are consistent with non-competitive market behavior. We test this hypothesis by developing an equilibrium model which is able to model coal producing nations as strategic players. We...

This paper analyses whether prices and trade-flows in the international market for metallurgical coals were subject to non-competitive conduct in the period 2008 to 2010. To do so, I develop mathematical programming models - a Stackelberg model, two varieties of a Cournot model, and a perfect...

The seaborne steam coal market changed in recent years. Trade volumes grew dynamically, important players emerged and since 2007 prices increased significantly and remained relatively high since then. In this paper we analyse market equilibria in the years 2006 and 2008 by testing for two...

During 2007 and 2008 steam coal prices soared to unprecedented levels. Since then much has been speculated about the drivers of these price peaks. This paper is concerned with the costs of steam coal allocation in the seaborne market and their influence on the price equilibrium. It presents an...

Ziel dieses Papers ist es, im Hinblick auf die in Deutschland geplante Einführung eines Qualitätsanreizsystems bei Elektrizitätsnetzbetreibern, eine geeignete Methode für die hierfür notwendige Bewertung der Netzzuverlässigkeit gleichbedeutend mit den wohlfahrtswirksamen Stromausfallkosten...

A model of the global gas market is presented which in its basic version optimises the future development of production, transport and storage capacities as well as the actual gas ows around the world assuming perfect competition. Besides the transport of natural gas via pipelines also the...

Ongoing climate change affects complex and long-lived infrastructures like electricity systems. Particularly for decarbonized electricity systems based on variable renewable energies, there is a variety of impact mechanisms working differently in size and direction. Main impacts for Europe...
