The performance of German water utilities: A (semi)-parametric analysis

Zschille, Michael; Walter, Matthias - 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...

AНАЛИЗ ОБОЛОЧКИ ДАННЫХ (DEA) – СОВРЕМЕННАЯ МЕТОДИКА ОПРЕДЕЛЕНИЯ ЭФФЕКТИВНОСТИ ПРОИЗВОДСТВА

Lissitsa, Aleksej; Babiéceva, Tamara - 2003

техническую эффективность определенного объекта (Decision Making Unit - DMU), как coотношение произведенных товаров и услуг …The Data Envelopment Analysis (DEA) is a relatively new method to measure Technical Efficiency (TE). TE of a Decision … expressed in the different measurement units. So, aggregation of the figures into cost or revenue groups become impossible. Such …

Monte Carlo simulations of DEA efficiency measures and hypothesis tests

Kittelsen, Sverre A. C. - 1999

The statistical properties of the efficiency estimators based on Data Envelopment Analysis (DEA) are largely unknown. Recent work by Simar et al. and Banker has shown the consistency of the DEA estimators under specific assumptions, and Banker proposes asymptotic tests of whether two subsamples...

Public-sector efficiency and interjurisdictional competition: An empirical investigation

Becker, Daniel Thomas - 2008

This paper investigates the performance and efficiency of the public sector in 74 countries worldwide for the years 1985, 1990, 1995 and 2000. Similar to what is done in Afonso / Schuhknecht / Tanzi (2005, Public Choice), I calculate performance measures for various fields of government policy,...

Measuring Residential Energy Efficiency Improvements with DEA

Grösche, Peter - 2008

This paper measures energy efficiency improvements of US single-family homes between 1997 and 2001 using a two-stage procedure. In the first stage, an indicator of energy efficiency is derived by means of Data Envelopment Analysis (DEA), and the analogy between the DEA estimator and traditional...

Potential gains from mergers in local public transport: an efficiency analysis applied to Germany

Walter, Matthias; Cullmann, Astrid - 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 - 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...

Research efficiency in manufacturing: an application of DEA at the industry level

Schmidt-Ehmcke, Jens; Zloczysti, Petra - 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...
