DEA for the Assessment of Regions' Ability to Cope with Disasters
Usually, DEA methods are used for the assessment of a region’s disaster vulnerability. However, most of these methods work with precise values of all the characteristics of the regions. At the same time, in real life, quite often most of the data consists of expert estimates or approximate values. In this regard, we propose to use modified DEA methods, which will take into account inaccuracy of the data. We apply these methods to the evaluation of wildfire preventive measures in the Russian Federation regions.
Data Envelopment Analysis (DEA) models and Free Disposal Hull (FDH) models were proposed almost simultaneously in the scientific literature. In DEA models, the constraints generate a convex set. For this reason, optimization methods and software are widely used for modeling and computations for these models. Non-convexity of production possibility set of FDH models refrained significantly the development of these models. In this paper, two methods are proposed for two-and three-dimensional frontier visualization for DEA and FDH models. Computational experiments using real-life datasets documented reliability and effectiveness of proposed methods.
In this article key approaches to an assessment of efficiency of processes of modernization of the enterprises are analyzed, the comparative analusis is carried out, the most adequate methods of an assessment of results od development of the enterprises are defined. The author analyzes the existing methodology of an assessment of the functioning of economic systems and proved the need of the analysis of non-linearity of a current of time for economic systems for the assessment of the efficiency of their development.
In this paper we describe the Data Envelopment Analysis (DEA) research design and its applications for effectiveness evaluation of company marketing strategies. We argue that DEA is an efficient instrument for use in academia and industry to compare a company’s business performance with its competitors’. This comparison provides the company with information on the closest competitors, including evaluating strategies with similar costs, but more efficient outcomes (sales). Furthermore, DEA provides suggestions on the optimal marketing mix to achieve superior performance.
In this paper we provide the methodology for evaluating ef- fectiveness of international sanctions using Data Envelopment Analysis (DEA), which we use for generating the network matrix for further anal- ysis. DEA is a non-parametric technique used to compare performance of similar units, such as departments or organizations. DEA has wide applications in all industries, and has been successfully used to compare performance of hospitals, banks, universities, etc. The most important advantage of this technique is that it can handle multiple input and out- put variables, even those not generally comparable to each other. We use the ”Threat and Imposition of Sanctions (TIES)” Data 4.0 for analysis. This database contains the largest number of cases of international sanctions (1412 from the years 1945-2005) imposed by some countries on others, takes into account simultaneous sanction imposition, and also estimates the cost of all sanctions - both for those who receive and those who impose them. As input variables for DEA model we use the impact of sender commitment, anticipated target and sender economic costs, and actual target and sender economic costs. As the output variable, we use the outcome of sanctions for senders. We describe how to use DEA cross-efficiency outputs to build the network of sanction episodes. Our proposed combination of DEA and network methodology allows us to cluster sanction episodes depending on their outcomes, and provides explanations of higher efficiency of one group of sanction episodes over the others.
The article deals with criminal-legal aspects of such restraint as commitment and house imprisonment, proposes measures for improving the legislative regulation of these restraints and their practical application, formulates conclusions concerning these problems reflection in mass media, as well as typical accusatory trends in this sphere of criminal-legal jurisdiction, their causes and preventive measures.
The article presents the experience of implementation of the Federal Target Programs within the territory of the North Caucuses Federal District and concludes that implementation of the dirigist model only does not ensure the desired result. It is proposed to focus the regional economic policy on development of the direct investment funds. Meanwhile, to take a region to the catching-up development curve requires a combination of the dirigist and institutional economic growth models.
