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...

Restricted participation in sequential markets may cause high price volatility and welfare losses. In this paper we therefore analyze the drivers of restricted participation in the German intraday auctin which is a short-term electricity market with quarter-hourly products. Applying a...

System security in electricity markets relies crucially on the interaction between demand and supply over time. However, research on electricity markets has been mainly focusing on the supply side arguing that demand is rather inelastic. Assuming perfectly inelastic demand might lead to delusive...

Despite regulation efforts, CO2 emissions from European road transport have continued to rise. Increased use of electricity offers a promising decarbonization option, both to fuel electric vehicles and run power-to-x systems producing synthetic fuels. To understand the economic implications of...

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 linear energy system model is presented which optimises the future development of electricity generation capacities and their dispatch in Europe. Besides conventional power plants, combined heat and power plants and power storages, the model considers technologies that support the future high...
