Immer wieder werden die sinkenden Stromgestehungskosten erneuerbarer Energien herangezogen, um zu argumentieren, dass die Stromkosten in Deutschland sinken werden. Die Stromgestehungskosten stellen jedoch keine belastbare Grundlage für die Einschätzung der zukünftigen Stromkosten dar....

We analyze the effect of price caps on equilibrium production and welfare in oligopoly under demand uncertainty. We find that high price caps always increase production and welfare as compared to the situation without price cap. Price caps close to marginal cost may lead to zero production,...

We analyze a market game where firms choose capacities under uncertainty about future market conditions and make output choices after uncertainty has unraveled. We show existence and uniqueness of equilibrium under imperfect competition and establish that capacity choices by strategic firms are...

In this paper we propose a three-level computational equilibrium model that allows to analyze the impact of the regulatory environment on transmission line expansion (by the regulator) and investment in generation capacity (by private firms) in liberalized electricity markets. The basic model...

In liberalized electricity markets strategic firms compete in an environment characterized by fluctuating demand and non-storability of electricity. While spot market design under those conditions by now is well understood, a rigorous analysis of investment incentives is still missing. Existing...
