COVID-19 and the efficiency of health systems in Europe

Lupu, Dan; Țigănașu, Ramona - In: Health Economics Review 12 (2022) 1, pp. 1-15

Background: This study aims at analyzing the efficiency of the health systems of 31 European countries in treating COVID-19, for the period January 1, 2020 - January 1, 2021, by incorporating some factors from a multidimensional perspective. Methods: The methodology used in the research was Data...

Testing productivity change, frontier shift, and efficiency change

Asmild, Mette; Kronborg, Dorte; Rønn-Nielsen, Anders - 2018

Inference about productivity change over time based on data envelopment (DEA) has focused primarily on the Malmquist index and is based on asymptotic properties of the index. In this paper we propose a novel set of significance tests for DEA based productivity change measures based on...

Exact tests on returns to scale and comparisons of production frontiers in nonparametric models

Rønn-Nielsen, Anders; Kronborg, Dorte; Asmild, Mette - 2019

When benchmarking production units by non-parametric methods like data envelopment analysis (DEA), an assumption has to be made about the returns to scale of the underlying technology. Moreover, it is often also relevant to compare the frontiers across samples of producers. Until now, no exact...

Stöver, Britta; Sibbertsen, Philipp - 2020

Due to the advancing economisation and the associated discussion on the distribution of public budgets and tax revenues, the efficiency of higher education institutions is increasingly coming into focus. Since the 2000s, more and more studies on the efficiency of German universities have been...

More on confidence intervals for partially identified parameters

Stoye, Jörg - 2008

merely weaken the superefficiency condition and with assumptions that remove it altogether. Imbens and Manski's confidence … region is found to be valid under weaker assumptions than theirs, yet superefficiency is required. I also provide a different … confidence interval that is valid under superefficiency but can be adapted to the general case, in which case it embeds a …

Identifying suspicious efficient units in DEA models

Krivonozhko, Vladimir E.; Førsund, Finn R.; Lychev, … - 2012

Applications of the DEA models show that inadequate results may arise in some cases, two of these inadequacies being: a) too many efficient units may appear in some DEA models; b) a DEA model may show an inefficient unit from the point of view of experts as an efficient one. The purpose of this...

Smoothing the frontier in the DEA models

Krivonozhko, Vladimir W.; Førsund, Finn R.; Lychev, … - 2016

Some inadequate results may appear in the DEA models as in any other mathematical model. In the DEA scientific literature several methods were proposed to deal with these difficulties. In our previous paper, we introduced the notion of terminal units. It was also substantiated that only terminal...

Analysis of the territorial efficiency of European Funds as an instrument to reduce labor gender differences

Blanco, Miguel; Bares, Lydia; Hrynevych, Oksana; … - In: Economies 9 (2021) 1, pp. 1-15

Gender equality has been one of the goals of the European Union since 1957. Article 157 of the Treaty on the Functioning of the European Union authorizes the European Parliament and the Council to adopt all those measures that guarantee the application of the principle of equality opportunities...

The efficiency of universities in achieving sustainable development goals

Perović, Lena Malešević; Kosor, Maja Mihaljević - In: Amfiteatru Economic Journal 22 (2020) 54, pp. 516-532

This paper investigates the efficiency of European universities in achieving Sustainable Development Goals (SDGs). We make use of newly published University Impact Rankings that account for SDGs, whereby institutions that achieved high scores are those that are, in addition to scientific...
