When analyzing economic aspects at regional levels, the spatial dimension of the data plays a crucial role. This is the case as spatial data and models are often characterized by two spatial effects, namely spatial dependence and spatial heterogeneity. The field of spatial econometrics is a separate field in econometrics that explicitly incorporates these spatial effects into econometric models. Following ...
In this paper the German congestion management regime is analyzed and future congestion management costs are assessed given a higher share of intermittent renewable generation. In this context, cost-based re-dispatching of power plants and technical flexibility through topology optimization are considered as market-based and technical congestion management methods. To replicate the current market regime ...
The North and Baltic Seas Grid is one of the largest pan-European infrastructure projects, increasing the potential of harnessing large amounts of renewable energy. This paper addresses the economic implications of different development scenarios of the North and Baltic Seas Grid on individual countries and stakeholders which may raise concerns about the implementation in largely nationally dominated ...
We analyse a stylized model of the world grain market characterized by a small oligopoly of traders with market power on both the supply and demand side. Crops are stochastic and exporting countries can impose export tariffs to protect domestic food prices. Our first results is that export tariffs are strategic complements and that for poor harvests equilibrium tariffs can explode (shedding some light ...
This article proposes a two-stage oligopoly model for the crude oil market. In a game of several Stackelberg leaders, market power increases endogenously as the spare capacity of the competitive fringe goes down. This effect is due to the specific cost function characteristics of extractive industries. The model captures the increase of OPEC market power before the financial crisis and its drastic ...
This dissertation focuses on selected aspects of network congestion arising in liberalized electricity markets and their management methods with a special weight placed on the integration of increased renewable generation in Europe and Germany. In a first step, the theoretical concepts of congestion management are introduced complemented by a review of current management regimes in selected countries. ...
The large-scale natural gas equilibrium model applied in Egging, 2013 combines long-term market equilibria and investments in infrastructure while accounting for market power by certain suppliers. Such models are widely used to simulate market outcomes given different scenarios of demand and supply development, environmental regulations and investment options in natural gas and other resource markets.. ...
When speculative price bubbles on real estate markets burst, the effects for the real economy are often devastating taking the form of substantial losses in production and employment. This paper discusses the degree to which institutional frameworks can prevent speculative bubbles from emerging and expanding. Comparing experiences in different countries indicates that, in Germany, institutional regulations ...
We analyze regulatory regimes for electricity transmission investment in the context of transformation of the power system towards renewable energy. We study three distinctive developments of the generation mix with different implications on network congestion, which may be either of temporary or permanent nature. We address the relative performance of a combined merchant-regulatory price-cap mechanism, ...
