Analysis of changes in technical efficiency of Russian agricultural organizations during the reform period
Studies on Russian Economic Development. 2014. P. 343–350.
The article analyzes the dynamics of the technical efficiency of agricultural organizations since the beginning of the reforms. The presence of a considerable number of non-effectively used and redundant resources, because of both the poor organization of farms and the insufficient development of market institutions in Russia, has been discovered. In general, based on the analysis, it has been concluded that there is a positive impact of market reforms on technical efficiency of agricultural organizations.

Periods of high market volatility put investors in a situation where conventional decision- making methods are less reliable. To improve returns, market participants need to understand which factors play a big role in portfolio formation. This article analyzes the determinants of Russian stock returns during the Covid-19 and the rise in geopolitical tension in 2022. ...

We consider a problem of estimating the rank correlations between inefficiency indices of decision making units and their JLMS estimators in a stochastic frontier model with exponentially distributed inefficiency. We derive expressions for asymptotic values of Kendall and Somers rank correlation coefficients and of Harrell’s C-index and provide an example of applying the obtained results ...

This paper summarizes practices of customer-driven services applied in the leading Russian bank to avoid the impact of financial sanctions (2014–2019). We show how economic sanctions and strict national policies triggered this bank to increase flexibility in customer care to attract more capital from their existing clients. The project comprised three stages: (1) to analyse ...

This paper addresses the problem of efficiency measurement in the performing arts by investigating the highly heterogeneous Russian theater market. We adopt data envelopment analysis and explore efficiency drivers, focusing on two groups of public theaters, classical academic and leading regional theaters. The scope of programming, observed through touring and new productions, is shown to ...

All countries have responded with a wide range of measures to stop the propagation of coronavirus. We apply best tube interval data envelopment analysis, in order to evaluate efficiency of quarantine measures using imprecise data. Using the Oxford COVID-19 Government Response Tracker’s (OxCGRT) data and given method, we construct time series of efficiency assessment of ...

This study is devoted to the analysis of the statistical relationship between the effectiveness of the bank and its specialization. Efficiency in the study is considered as a metric that evaluates the quality of management of an organization. Specialization in this case refers to the bank's concentration on certain types of banking products. The specifics ...

A technique for assessing the concordance between true inefficiency of decision making units in a basic stochastic frontier model and their JLMS estimates is proposed. An approximate formula for Harrell’s C-index is derived for the case of half-normal distribution of inefficiency component. A simulation study shows that the approximation error is about 0.01 and that ...

In this paper we propose a methodology for assessing the efficiency of technology transfer through merger and acquisition (M&A) and empirically estimate the effect of key factors impacting it. We implement data envelopment analysis (DEA) to calculate an efficiency score of the technology transfer process. The DEA efficiency score integrates a set of outputs (post-merger ...

Stochastic frontier model may be used to rank firms according to estimated inefficiency level, but the accuracy of the obtained rankings cannot be directly measured, because the true inefficiency levels are unobservable. The paper proposes the method of approximate calculation of Kendall's rank correlation coefficient and Harrell's C-index between the true and the estimated inefficiency ...

Рассматривается модель стохастической границы — линейная регрессионная модель, связывающая показатель деятельности субъекта принятия решения (например, объём производства предприятия) с затратами ресурсов и используемая для определения эффективности субъектов. На основании серии стохастических экспериментов определяется способность модели ранжировать субъекты по эффективности — рассчитываются коэффициент ранговой корреляции Спирмена и коэффициент согласованности Харрелла в зависимости от дисперсий двух компонент ...

The paper examines technical efficiency of Russian firms during the period from 2013 to 2018 applying the stochastic production frontier method. The estimates obtained indicate that technical efficiency grows with firm size and declines with its age. While macroeconomic situation deteriorated in 2015–2016, technical efficiency in most industries changed insignificantly. However, the number of industries with a negative trend ...

Performance evaluation enables decision makers (DMs) to have a better view about the weaknesses and strengths of leading units to improve efficiencies as a crucial goal. Data envelopment analysis (DEA) is the most popular technique to measure performance efficiency of decision making units (DMUs). However, conventional DEA is unable to consider uncertainty of input and ...
