We test the hypothesis that rising prices of emission allowances have a stronger impact on wholesale electricity prices than falling prices (asymmetric cost pass-through). Using an autoregressive distributed lag model, we confirm this hypothesis for the German market
We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some situations ...
We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic several-layer model of European natural gas supply, consisting of upstream natural gas producers, traders in each consuming European country (or region), and final demand. Our model results suggest rather modest changes in the overall ...
We present a model with firms selling (homogeneous) products in two imperfectly segmented markets (a "high-demand" and a "low-demand" market). Buyers are mobile but restricted by transportation costs, so that imperfect arbitrage occurs when prices differ in both markets. We show that equilibria are distorted away from Cournot outcomes to prevent consumer arbitrage. Furthermore, a merger can lead to ...
In Germany, emission allowances (European Union Allowances, EUAs) for the first trading period (2005-2007) were allocated completely free of charge. In the second trading period (2008-2012) annual volumes of 40 million EUAs will be sold (Article 19 ZuG (Zuteilungsgesetz – The German Allocation Act) 2012). After an initial phase during which EUAs have been sold by the state-owned bank KfW Bankengruppe ...
