Die Entscheidung der Organisation erdölexportierender Länder (OPEC) im Herbst 2014, ihre Förderquote trotz des dramatischen Falls der Rohölpreise nicht zu senken, hat diese Gruppe wieder einmal ins Rampenlicht der öffentlichen Diskussion gerückt. Obwohl einige der wichtigsten...

The recent decision by the Organization of the Petroleum Exporting Countries (OPEC) not to decrease their output quota in spite of a drastic decline of crude oil prices has brought renewed attention to this supplier group dominating the crude oil market. However, the empirical evidence that OPEC...

We discuss potential developments of the world natural gas industry through 2030. We use the World Gas Model (WGM), a multi-period strategic representation of the global natural gas sector, between 2005 and 2030. We specify a 'base case' and then analyse the sensitivity of the world natural gas...

We investigate the exertion of market power in the global crude oil market over the past years. Recognizing the difficulty of identifying market power in the crude oil market by empirical studies, we propose a numerical partial equilibrium model formulated as a mixed complementarity problem. Our...

Climate change mitigation and the transformation to a global low-carbon economy is a pressing issue in policy discussions and international negotiations. The political debate is supported by the scientific community with a large number of projections, pathway simulations and scenario analyses of...

Lack of transmission capacity hampers the efficient integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate to what extent the expansion of the transmission grid promotes competition, efficiency, and welfare. This work...

Assessing and quantifying the impacts of technological, economic, and policy shifts in the global energy system requires large-scale numerical models. We propose a dynamic multi-fuel market equilibrium model that combines endogenous fuel substitution within demand sectors and in power...

The liberalisation of the natural gas markets and the importance of natural gas as a transition fuel to a low-carbon economy have led to the development of several large-scale equilibrium models in the last decade. These models combine long-term market equilibria and investments in...
