The restructuring of telecommunication in Central and Eastern Europe occurs at a time when the classical structures of telecommunication are falling apart worldwide. Coming from the socialist system in which telecommunication did not exist as an independent economic activity, the Eastern...

This study analyzes issues related to "green", i.e. low-carbon electricity investment in Europe. While traditionally the focus of attention was on green transmission lines, it has become clear in the course of this study that even though high-voltage electricity transmission is an important...

We apply the EMF 23 study design to simulate the effects of the reference case and the scenarios to European natural gas supplies to 2025. We use GASMOD, a strategic severallayer model of European gas supply, consisting of upstream natural gas producers, traders in each consuming European...

In this paper, we present a nonparametric comparative efficiency analysis of 179 communal public transport bus companies in Germany (1990-2004). We apply both deterministic data envelopment analysis (DEA) and bootstrapping to test the robustness of our estimates and to test the hypothesis of...

In this paper, we analyze structural changes in long-term contracts in the international trade of natural gas. Using a unique data set of 262 long-term contracts between natural gas producers and importers, we estimate the impact of different institutional, structural and technical variables on...

This paper provides a cross-country efficiency analysis of electricity distribution companies in East European transition countries (Poland, Czech Republic, Slovakia and Hungary). We compare the relative technical efficiency of East European regional distribution companies (RDCs) among...
