Marktstrukturen in der Trinkwasserversorgung

Mit mehr als 6.000 Unternehmen kann die Trinkwasserversorgung Deutschlands im internationalen Vergleich als höchst fragmentiert angesehen werden. Während die Trinkwasserversorgung in zahlreichen Ländern durch eine ähnliche Fragmentierung gekennzeichnet ist, gibt es aber auch Beispiele höchst konsolidierter Versorgungsstrukturen: so gibt es in England und Wales lediglich 22 Trinkwasserversorgungsunternehmen ...

Market Power, Fuel Substitution and Infrastructure: A Large-Scale Equilibrium Model of Global Energy Markets

Assessing and quantifying the impacts of technological, economic, and policy shifts in the global energy system require large-scale numerical models. We propose a dynamic multi-fuel market equilibrium model that combines endogenous fuel substitution within demand sectors and in power generation, detailed infrastructure capacity constraints and investment, as well as strategic behaviour and market power ...

Noise Expectations and House Prices: The Reaction of Property Prices to an Airport Expansion

We examine the effects of an airport expansion on the prices of houses and apartments located under the planned flight paths. We focus on the role of expectations of aircraft noise during the expansion of Berlin-Brandenburg International Airport. The publication of the flight paths can be seen as an exogenous event. It provides local residents and potential home buyers with reliable information in ...

Elasticities of Supply for the US Natural Gas Market

In this paper we investigate natural gas producer's reactions to changes in market prices. We estimate price elasticities of aggregated supply in the most competitive market for natural gas: the United States. Using monthly time series data form 1987 to 2012 our analysis is based on an Autoregressive Distributed Lag (ARDL) Bound Cointegration approach to obtain short and long-run elasticities of natural ...

The Welfare Impact of Parallel Imports: A Structural Approach Applied to the German Market for Oral Anti-Diabetics

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of demand and, based on an oligopolistic model of multiproduct firms, we then recover the marginal costs and ...

Mietpreisbremse: Wohnungsmarktregulierung bringt mehr Schaden als Nutzen

Die Mietpreise in Deutschland steigen seit einigen Jahren wieder stärker. Vor allem in Metropolen wie Berlin, Hamburg und München lagen die Zunahmen zuletzt über dem gesamtdeutschen Durchschnitt von rund zwei Prozent. Die Bundesregierung möchte auf diese Entwicklung mit einer Mietpreisbremse reagieren, die unter anderem die Mieten bei Wiedervermietungen beschränken soll. Doch sind staatliche Eingriffe ...

Von einer Explosion der Mieten kann keine Rede sein: Sechs Fragen an Konstantin Kholodilin

Monitoring der Kosten- und Nutzenwirkungen des Ausbaus erneuerbarer Energien im Jahr 2013: Untersuchung im Rahmen des Projekts "Wirkungen des Ausbaus erneuerbarer Energien (ImpRES)", gefördert vom Bundesministerium für Wirtschaft und Energie

Network Expansion to Mitigate Market Power: How Increased Integration Fosters Welfare

Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. This work proposes a three-stage model for grid investment: a benevolent planner decides on network upgrades, considering welfare benefits ...

National-Strategic Investment in European Power Transmission Capacity

The transformation of the European energy system requires substantial investment in transmission capacity to facilitate cross-border trade and to efficiently integrate renewable energy sources. However, network planning in the EU is still mainly a national prerogative. In contrast to other studies aiming to identify the pan-European (continental) welfare-optimal transmission expansion, we investigate ...
