Some Practical Guidance for the Implementation of Propensity Score Matching

Caliendo, Marco; Kopeinig, Sabine - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2005

researcher has decided to use PSM, he is confronted with a lot of questions regarding its implementation. To begin with, a first … decision has to be made concerning the estimation of the propensity score. Following that one has to decide which matching …. Each implementation step involves a lot of decisions and different approaches can be thought of. The aim of this paper is …

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...

Estimating Alternative Technology Sets in Nonparametric Efficiency Analysis: Restriction Tests for Panel and Clustered Data

Neumann, Anne; Nieswand, Maria; Schubert, Torben - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2013

Nonparametric efficiency analysis has become a widely applied technique to support industrial benchmarking as well as a variety of incentive- based regulation policies. In practice such exercises are often plagued by incomplete knowledge about the correct specifications of inputs and outputs....

Evaluating Greek Equity Funds Using Data Envelopment Analysis

Babalos, Vassilios; Caporale, Guglielmo Maria; … - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2009

This study assesses the relative performance of Greek equity funds employing a non-parametric method, specifically Data Envelopment Analysis (DEA). Using an original sample of cost and operational attributes we explore the effect of each variable on funds' operational efficiency for an...

Allocative Efficiency Measurement Revisited: Do We Really Need Input Prices?

Badunenko, Oleg; Fritsch, Michael; Stephan, Andreas - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2006

The traditional approach to measuring allocative efficiency is based on input prices, which are rarely known at the firm level. This paper proposes a new approach to measure allocative efficiency which is based on the output-oriented distance to the frontier in a profit - technical efficiency...

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...

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...

Technological Change and Transition: Relative Contributions to Worldwide Growth during the 1990s

Badunenko, Oleg; Henderson, Daniel J.; Zelenyuk, Valentin - DIW Berlin (Deutsches Institut für Wirtschaftsforschung) - 2007

In this paper we used the procedures developed in the Kumar and Russell (2002) growth-accounting study to examine cross-country growth during the 1990's. Using a data set comprising developed, newly industrialized, developing and transitional economies, we decomposed the growth of output per...
