The benefits captured in an appraisal of a railway investment are determined by what timetables the analyst assumes in the scenarios with and without the investment. Without an explicit, objective and verifiable principle for which timetables to assume, the appraisal outcome is virtually...

This paper analyzes the effects of the green transformation on the German electricity sector with respect to the energy political triangle. It focuses on how the development of renewable energies will affect security of electricity supply. In a cost-benefit analysis, the value of supply security...

Under conditions of risk it makes a difference whether the discount rate is determined as an expected present or as an expected future value. This difference which is dubbed as the Weitzman-Gollier puzzle has stimulated an intensive discussion which, however, is somewhat confusing. In this paper...

Uncertainty has an almost negligible impact on project value in the standard economic model. I show that a comprehensive evaluation of uncertainty and uncertainty attitude changes this picture fundamentally. The illustration of this result relies on the discount rate, which is the crucial...

We report on the panel discussion held at the ICDM'10 conference on the top 10 data mining case studies in order to provide a snapshot of where and how data mining techniques have made significant real-world impact. The tasks covered by 10 case studies range from the detection of anomalies such...

The social cost of carbon - or marginal damage caused by an additional ton of carbon dioxide emissions - has been estimated by a U.S. government working group at $21/tCO2 in 2010. That calculation, however, omits many of the biggest risks associated with climate change, and downplays the impact...

In 2010, the European Commission has formulated some clear objectives to come to one single European telecommunications market by 2020 in its Digital Agenda. These objectives require large investments in new infrastructure. Optical access networks can cope with the high bandwidth required by...

Previous literature has identified considerable non-pecuniary costs to macroeconomic fluctuation and uncertainty. The present paper investigates whether and to what extent labor market institutions can mitigate those costs. We study how life satisfaction of European citizens is affected by...

That climate policies are costly is evident and therefore often creates major fears. But the alernative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are, and in addition, they are substitutes. This brings climate policies naturally in the...
