Valuing Environmental Factors in Cost-Benefit Analysis Using Data Envelopment Analysis
Kuosmanen, Timo - 2006
Environmental cost-benefit analysis (ECBA) refers to social evaluation of investment projects and policies that involve significant environmental impacts. Valuation of the environmental impacts in monetary terms forms one of the critical steps in ECBA. We propose a new approach for environmental...

Evaluating Greek equity funds using Data Envelopment Analysis
Babalos, Vassilios; Caporale, Guglielmo Maria; … - 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...

Effects of Ownership on Hospital Efficiency in Germany
Tiemann, Oliver; Schreyögg, Jonas - In: BuR - Business Research 2 (2009) 2, pp. 115-145
The objective of our study was to evaluate the efficiency of public, private for-profit, and private non-profit hospitals in Germany. First, bootstrapped data envelopment analysis (DEA) was used to evaluate the efficiency of a panel (n = 1,046) of public, private for-profit, and private...

Changes in hospital efficiency after privatization
Tiemann, Oliver; Schreyögg, Jonas - 2011
We investigated the effects of privatization on hospital efficiency in Germany. To do so, we obtained bootstrapped DEA efficiency scores in the first stage of our analysis and subsequently employed a difference-in-difference matching approach within a panel regression framework. Our findings...

Measuring local government technical (in)efficiency: An application and comparison of FDH, DEA and econometric approaches
Geys, Benny; Moesen, Wim - 2008
Economic efficiency – understood in terms of jurisdictions providing a maximum amount of output for a given level of inputs – is one potential means to evaluate public policies. Various approaches, however, co-exist to measure the (technical) efficiency of organizations. Given that these...

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...

Financial performance measurement of Hungarian retail food companies
Fenyves, Veronika; Bács, Zoltán; Karnai, Laura; Nagy, … - In: Contemporary Economics 12 (2018) 4, pp. 459-472
The comparison of company performances, i.e., benchmarking, is becoming more and more critical. Presently, companies mostly use traditional financial ratios to evaluate their financial performance. We also use financial ratios to measure and compare company performances, from which we create...

A Generalization of the Calendar Time Portfolio Approach and the Performance of Private Investors
Hoechle, Daniel; Zimmermann, Heinz - 2007
We present a regression-based generalization of the calendar time portfolio approach which allowsfor the inclusion of continuous and multivariate investor or firm characteristics in the analysis. Ourmethod is simple to apply and it ensures that the statistical results are heteroscedasticity...
