Innovation, R&D Efficiency and the Impact of the Regulatory Environment: A Two-Stage Semi-Parametric DEA Approach
Cullmann, Astrid; Schmidt-Ehmcke, Jens; Zloczysti, Petra - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009
This paper assesses the relative efficiency of knowledge production in the OECD using a nonparametric DEA approach. Resources allocated to R&D are limited and should therefore be used efficiently given the institutional and legal constraints. This paper presents efficiency scores based on an...

The Performance of German Water Utilities: A (Semi)-Parametric Analysis
Zschille, Michael; Walter, Matthias - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2011
Germany's water supply industry is characterized by a multitude of utilities and widely diverging prices, possibly resulting from structural differences beyond the control of firms' management, but also from inefficiencies. In this article we use Data Envelopment Analysis and Stochastic Frontier...

Consolidating the Water Industry: An Analysis of the Potential Gains from Horizontal Integration in a Conditional Efficiency Framework
Zschille, Michael - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2012
The German potable water supply industry is regarded as being highly fragmented, thus inhibiting high potentials for efficiency improvements through consolidation. Focusing on a hypothetical restructuring of the industry, we apply Data Envelopment Analysis (DEA) to analyze the potential...

Research Efficiency in Manufacturing: An Application of DEA at the Industry Level
Schmidt-Ehmcke, Jens; Zloczysti, Petra - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009
This paper analyzes research efficiency at the industry level in manufacturing for 13 European member and four nonmember countries during 2000 and 2004. A unique dataset was compiled that matches patent applications at the European Patent Office (EPO) to industry-specific R&D inputs from EU...

Potential Gains from Mergers in Local Public Transport: An Efficiency Analysis Applied to Germany
Walter, Matthias; Cullmann, Astrid - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2008
We analyze potential gains from hypothetical mergers in local public transport using the non-parametric Data Envelopment Analysis with bias corrections by means of bootstrapping. Our sample consists of 41 public transport companies from Germany's most densely populated region, North...

Konzessionsmodelle für Fernstraßen in Deutschland: eine ökonomische Analyse der Risikoallokation beim F- und A-Modell
Beckers, Thorsten; Hirschhausen, Christian von - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2003
This paper analyzes the risk allocation in concession models for German highways, according to the "F-Model" and the "A-Model". We first assess the deficits of traditional construction and management of highways in Germany and present the two concession models. Next, theoretical backgrounds and...
