Der Workshop hat die Diskussion von Modellansätzen und -ergebnissen zu aktuellen Fragen des Stromsektordesigns zum Ziel. Dabei sollen sowohl konzeptionelle Fragen der Modellierung als auch relevante empirische Probleme (Daten, Ergebnisinterpretationen, etc.) behandelt werden. Zu jedem Themenblock gibt es einen bzw. mehrere Diskutanten sowie eine allgemeine Diskussion. Die Veranstaltung...
The German decision to finally phase-out nuclear electricity has led to a debate on its effects on electricity prices, emission prices in the European emission trading system, as well as on international electricity trade. We investigate these effects with a Electricity market model for Europe with investments in power plants under oligopolistic conditions in Germany. We find modest price increases ...
Questions about the future availability of inexpensive coal supplies are rising. In this paper a numerical model is developed to investigate the evolution of the international market for steam coal used for electricity generation. The "COALMOD-World" model is an equilibrium model that computes future trade flows, infrastructure investments and prices until 2030. The model includes the major domestic ...
Better understanding the innovative process of renewable energy technologies is important for tackling climate change. Though concentrating solar power is receiving growing interest, innovation studies so far have explored innovative activity in solar technologies in general, ignoring the major differences between solar photovoltaic and solar thermal technologies. This study relies on patent data to ...
This paper studies technological change in renewable energies, providing empirical evidence on the determinants of innovative activity with a special emphasis on the role of knowledge spillovers. We investigate two major renewable energy technologies - wind and solar - across a panel of 21 OECD countries over the period 1978 to 2004. Spillovers may occur at the national level, either within the same ...
We investigate the role of crude oil spot and futures prices in the process of price discovery by using a cost-of-carry model with an endogenous convenience yield and daily data over the period from January 1990 to December 2008. We provide evidence that futures markets play a more important role than spot markets in the case of contracts with shorter maturities, but the relative contribution of the ...
Governments willing to commit themselves to maintain carbon prices at or above a certain level face the challenge that their commitments need to be credible both for investors in low-carbon technology and for foreign governments. This article argues that governments can make such commitments by issuing long-term put option contracts on the price of CO2 allowances. This mechanism gives investors the ...
