Zusammenfassung Für die umweltorientierte Verflechtungsanalyse wird eine Verdichtung der in Input-Output- Tabellen enthaltenen Informationen gewünscht, wobei die quantitative Bedeutung der Verflechtungen weiter erkennbar sein soll. Dazu wird am Beispiel kumulierter Energieaufwendungen ein...

In this paper, the role of the Internet as an instrument for investor relations activities is addressed. The empirical study compares the Internet investor relations activities of US, UK and German corporations. A sample comprising the respective country's relevant stock market 100 index (S&P,...

Distributed Generation (DG) units are said to have the potential to become an integral part of the future power systems. Today, DG units are characterised by high specific investment costs, but nevertheless are politically promoted because of their high degree of energy efficiency and their...

Natural gas storages may be valued by applying real options theory. However, it is crucial to take into account that most evolving gas markets, like the German spot market, lack liquidity. This implies that large-scale operation of storages reduces the achievable operating margin since storage...

The ongoing transformation of the European energy system comes along with new challenges, notably increasing amounts of power generation from intermittent sources like wind and solar. How current objectives for emission reduction can be reached in the future and what the future power system will...

Improvements in the building stock insulation and the replacement of heating systems will have to take place within the next decades in order to lower heat demand and the associated carbon emissions of the building sector. The current study presents an integrated, iterative modelling approach to...

It is common practice to base investment decisions on price projections which are gained from simulations using price processes. The choice of the underlying process is crucial for the simulation outcome. For power plants the core question is the existence of stable long-term cointegration...

We analyze the treatment and impact of idiosyncratic or firm-specific risk in regulation. Regulatory authorities regularly ignore firm-specific characteristics, such as size or asset ages, implying different risk exposure in incentive regulation. In contrast, it is common to apply only a single...
