Increased spending on healthcare systems in many countries tends to attract attention to their efficiency. The aim of this paper is to evaluate the efficiency of healthcare systems in the OECD countries and indicate causes of inefficiency by applying Data Envelopment Analysis (DEA) and using additive and super-efficiency models. The homogeneity of the sample is assessed and outliers are excluded. A ranking is established on the basis of efficiency scores. By means of DEA, fully efficient units are identified, forming a reference set (of best practice) for inefficient countries to follow.

The present paper considers the problem of the success of a research project evaluated by its outputs (which can be seen as the project’s success measures) related to its inputs (constituting the project’s success factors). Data Envelopment Analysis (DEA) models are used. The inputs and outputs are selected on the basis of a review of the literature. Two models are applied to a set of research projects implemented in Poland. Advantages and disadvantages of the approach are shown. In particular, the selection of inputs, outputs and their weights needs to be researched further. But the models used in the paper, in spite of their imperfection and lack of generality, considerably help to assess and compare the projects. Therefore, DEA is an important tool for the evaluation of R&D activities.

Artykuł przybliża problematykę efektywności wydatków jednostek samorządu terytorialnego. Jego głównym celem jest porównanie wyników – uzyskanych dzięki zastosowaniu nieparametrycznej metody Data Envelopment Analysis (DEA) – w ocenie efektywności wydatków publicznych. Autorzy dokonali przeglądu dotychczasowych badań na przykładzie ośmiu europejskich państw. Stosownie do przyjętego celu pracy w pierwszej kolejności scharakteryzowano kategorię wydatków jako finalnego efektu obranej przez jednostkę samorządu terytorialnego polityki fiskalnej. W dalszej części omówiono założenia metody DEA oraz możliwości wykorzystania jej do pomiaru efektywności. Zgodnie z twierdzeniem, że kierunki wydatkowania środków publicznych na realizację zadań określane powinny być w sposób planowy i celowy, a struktura ich rozdysponowania obrazuje preferencje władz co do stopnia realizacji zadań publicznych i społecznych, interpretacją objęto analizę zmiennych wyjściowych oraz sformułowano uogólnione wnioski z badań.

The author considers in the article estimation of the technical efficiency, which measures the ability of the company to obtain the maximum output from given inputs or to use the minimum input to achieve given outputs. The comparison of two approaches: deterministic (on the example of Data Envelopment Analysis) and stochastic (on the example of Stochastic Frontier Approach) has been carried out, the advantages and disadvantages of both were also described. These methods were chosen because they have become popular in polish research. In the article the possible limitations and problems, which may influence results of studies conducted by using these methods, were considered.

Out-of-pocket expenditures are a significant barrier in accessing health services. This paper aims to analyse the structure of financing system in the context of the performance indicators of healthcare systems. The study was conducted for the 28 countries of the former Eastern bloc in the years 2000 and 2013, based on data from the World Health Organization. In the DEA-CCR input-oriented model, inputs are the percentage share of private spending in the total expenditure on healthcare and the percentage share of out-of-pocket patient spending in total private spending. The outputs are life expectancy and mortality rate. A ranking of the countries was created and the differences between the two study periods, as well the desired directions of changes in the financing structure were pointed out.

The output of a generator in power plant is the electricity, and it consists of two parts, active and reactive power. These quantities are expressed as complex numbers in which the real part is the active power and the imaginary part is the reactive power. Reactive power plays an important role in an electricity network. Ignoring it will exclude a lot of information. With regard to the importance of the generators in power plants, surely, calculating the efficiency of these units is of great importance. Data Envelopment Analysis (DEA) is a nonparametric approach to measure the relative efficiency of Decision-Making Units (DMUs). Since the generators data are complex numbers, thus, if we the use classical DEA models in order to measure the efficiency of the generators in power plants, the reactive power cannot be considered, and the measurement is limited to the real number of electric power. In this paper, a new DEA model with complex numbers is developed in order to assess the performance of the power plant generators.

The subject of the research presented in this paper is the efficiency of key commercial banks in Poland. The research sample includes 12 banks listed on the Warsaw Stock Exchange, which hold over 80% of the assets of the entire commercial banks sector in Poland. The research period is 2013-2018. The aim of the research was to examine whether the largest commercial banks are more efficient than the others and to determine the main reasons for the inefficiency of commercial banks. Data Envelopment Analysis (DEA) was used as the research method. The obtained results indicate that the average efficiency is 0.903. It turns out that the largest banks are on average quite efficient and do not have much room for improvement. In the case of large banks, the average technical efficiency PE is 0.96, while in the case of pure technical efficiency PTE it is as high as 0.99. This indicates that the largest Polish banks manage their resources very efficiently.

Przedmiotem badania przedstawionego w niniejszym artykule jest efektywność kluczowych banków komercyjnych w Polsce. Próba badawcza obejmuje 12 banków notowanych na Giełdzie Papierów Wartościowych w Warszawie, które posiadają ponad 80% aktywów całego sektora banków komercyjnych w Polsce. Okres badania to lata 2013-2018. Celem badania było sprawdzenie, czy największe banki komercyjne są bardziej efektywne od pozostałych oraz wskazanie głównych przyczyn nieefektywności banków komercyjnych. Jako metodę badawczą zastosowano Data Envelopment Analysis (DEA). Uzyskane wyniki wskazują, że przeciętna efektywność wynosi 0,903. Okazało się także, że największe banki są przeciętnie dość efektywne i nie mają zbyt wielkich możliwości poprawy – przeciętna efektywność techniczna wynosi 0,96, w przypadku zaś „czystej efektywności technicznej” PTE wynosi ona aż 0,99. To wskazuje, że największe polskie banki zarządzają swoimi zasobami bardzo efektywnie.

This article presents a model to measure and assess the relative efficiency of technical universities. The analysis was performed using publically available data from 2011 for 18 universities using the composite indicators method and the SBM Data Envelopment Analysis model. Fourteen indicators for efficiency were defined in the five areas of the university performance: research, teaching, scientific staff development, quality of teaching processes and public funding. Inefficient units were identified, based on their calculated efficiency scores and the directions for change to allow them to reach greater efficiency were suggested. Methods used to assess efficiency allowed the combined effect of all relevant factors to be taken into account which described the basic operations of the university.

Financial shortfalls are typical for protected areas (PA) in many countries. The data collected in the mid-90s of the twentieth century indicate that globally there is a deficit in the amount of $2.3 billion for efficient protection of PA. Therefore, there is a growing interest in accounting for PA costs and a need to increase the efficiency of using resources. The article described Polish National Parks (NP) and presented the analysis of efficiency of using their resources with DEA method. The research was conducted in the area of tourist and scientific activity, which, along with the protection of biodiversity is the essence of NP.

Niedobory finansowania są wspólne dla obszarów chronionych (PA) w wielu krajach. Dane zebrane w połowie lat 90. XX wieku świadczą, że w skali świata występuje deficyt w kwocie 2,3 mld USD na skuteczną ochronę funkcjonujących PA. Dlatego rośnie zainteresowanie rozliczaniem kosztów funkcjonowania PA oraz potrzeba zwiększenia efektywności wykorzystania środków finansowych. W artykule scharakteryzowano polskie parki narodowe (PN) oraz przeprowadzono analizę efektywności wykorzystania ich zasobów przy zastosowaniu metody Data Envelopment Analysis (DEA). Badanie przeprowadzono w obszarze działalności turystycznej i naukowej, które wraz z ochroną różnorodności biologicznej stanowią istotę funkcjonowania PN.

Background: During the last four years, the banking sector in Bosnia and Herzegovina has been facing crisis which has caused the stagnation within the sector. Still, the results within the sector vary to a great extent from bank to bank. Objectives: The efficiency score is assessed for each bank and serves as a basis for further comparisons between banks in the period between 2008 and 2010. Methods: A modified model of Data Envelopment Analysis (DEA) has been used in order to combine several financial indicators simultaneously in a unique efficiency measure. The model provides a rounded judgement on a bank's relative efficiency. Results: Efficiency of individual banks varied throughout the observed period and not all of the banks were a part of the negative banking sector trend induced by the crisis. There is no significant difference between performance of banks in different entities of Bosnia and Herzegovina, and between smaller and larger banks. Conclusions: The results of the study can be used by bank managers to assess the performance of their banks, as observing financial ratios separately can result in a misleading conclusion. The most valuable practical implications of the findings are the provided feasible targets for the three observed years.

Research background: The insurance market is an important part of the financial system. The international concept of insurance operations brings certainty and helps to balance the economic results. Purpose of the article: The aim of the paper is to compare the efficiency of life insurance of commercial insurance companies in the Czech Republic and Poland using the Data Envelopment Analysis model (DEA). Methods: The methods used in the paper are descriptive statistics, DEA model and Tobit regression model. DEA models are nonparametric quantitative models for efficiency assessment. They use linear programming to transform multiple inputs into multiple outputs. The efficiency of the subjects analyzed is assessed based on the efficiency scores. Findings & Value added: The subject of our analysis was 17 commercial insurance companies in the Czech Republic and 26 commercial insurance companies in Poland. Ten insurance companies were efficient on the common Czech-Polish insurance market. The share of efficient insurance companies was approximately equal. The arithmetic mean of the efficiency scores was higher in Poland than in the Czech Republic. The variability of the efficiency scores of Czech insurance companies was greater than the variability of the efficiency scores of Polish insurance companies. The correlations with efficiency score as the dependent variable and with market share as the independent variable of Tobit regression were very low.

The aim of this study is to evaluate and compare the financial and managerial efficiency of healthcare inpatient systems in one country. The research question is: What factors give rise to efficiency variations within the regional healthcare system (hospitals)? A two-step approach proposed by Simar and Wilson has been applied. The first step applies the Data Envelopment Analysis to estimate the unit (i.e., a Polish region in our research) efficiency scores, which is followed by truncated regression with double bootstrapping to examine the impact of uncontrolled variables on efficiency scores. The efficiency scores obtained in 16 regions from the output-oriented model with non-increasing returns to scale indicate a full effectiveness of five regions. The DEA scores of the other regions exceed the value of 0.8 and do not differ significantly. The bootstrap-corrected DEA scores do not considerably change the efficiency assessment. The direction of the impact of the ‘percentage of people above 65 years of age’ variable and the ‘growth rate of total liabilities on efficiency’ variable is opposite to that observed for the ‘average salary’ variable. The results obtained suggest that the regional healthcare system efficiency can be affected by the ageing population, pay pressure, and liabilities.

The study investigates the differences in technical, pure technical, and scale efficiencies of domestic and foreign banks in Algeria over the period of 2000–2012. The study uses annual data of 10 foreign banks and 05 domestic banks operated in Algeria. The input-oriented Data Envelopment Analysis model is used to measure the banks’ efficiency score. In addition, a set of parametric and non-parametric tests are used for investigating the differences in efficiency between foreign and domestic banks. The findings reveal that the banks in Algeria could improve their technical efficiency by 23%. In addition, it seems that banks in Algeria suffer from the scale inefficiency. On the other hand, the foreign banks are more technically efficient than domestic banks. The superiority of foreign banks in technical efficiency is due to their superiority in the scale efficiency.

Celem pracy jest ocena efektywności finansowej i zasobów gospodarczych nadleśnictw w Polsce Południowej w 2012 roku za pomocą metody DEA. W ramach analizy efektywności finansowej, określono maksymalne, potencjalne przychody ze sprzedaży drewna dla poszczególnych nadleśnictw przy danych kosztach. Z kolei, przy przeprowadzaniu analizy efektywności zasobów gospodarczych, próbowano określić maksymalną ilość drewna, możliwą technologicznie do pozyskania przy danych zasobach. Szczególną uwagę poświęcono jednostkom uznanym za skrajnie nieefektywne, dla których przeprowadzono analizę za pomocą tzw. wzorców efektywności. Dodatkowo, w celu wprowadzenia rankingu wśród jednostek efektywnych i uszczegółowienia interpretacji miar efektywności, wykorzystano model nadefektywności.

The aim of this paper is to evaluate financial and economic resources efficiency of forest districts in the South Poland in 2012 by means of DEA. Within financial efficiency analysis, maximal potential lumber sales income for the forest districts at fixed costs was determined. Next, within economic resources efficiency analysis, the maximal amount of lumber is evaluated, which is technologically achievable at some fixed resources. Special attention was paid to extremely inefficient units, where an analysis using the so-called benchmarks of efficiency was performed. Additionally, in order to rank the units classified as efficient and to expand the interpretation of the efficiency measures, the super-efficiency model was employed.

This study adopted two-stage DEA to estimate the technical efficiency scores and assess the impact of the two most important components of fossil fuel associated with oil production on macroeconomic efficiency of Seven oil producing African countries during 2005-2012. Our results showed that increasing the consumption of natural gas would improve technical efficiency. Furthermore, increasing the share of fossil fuel in total energy consumption has negative effect on the efficiency of the economies of the top African oil producers. Also, we found that increasing the consumption of primary energy improves efficiency in these economies. We therefore, recommend that governments and other stakeholders in the energy industry should adopt inclusive strategies that will promote the use of natural gas in the short term. However, in the long-run, efforts should be geared towards increasing the use of primary energy, thereby reducing the percentage share of fossil fuel in total energy consumption.
