Advice from Above: Sociologists Have Assessed the Impact that Priests Have on How Their Parishioners Vote
Political preferences of at least 21% of Orthodox voters in Russia may be influenced by the clergy and their fellow believers. Based on an online survey of 2,735 respondents, HSE University sociologists Kirill Sorvin and Maksim Bogachev concluded that religion has a considerable impact on people’s political choices. The scholars assume that the share of those who vote ‘in an Orthodox way’ may be higher: many respondents were under 34, and young people are a minority among Orthodox believers in Russia.

Efficient, but Not without Help: How Russian State-owned Banks Differ from Their Foreign Counterparts
HSE University economists analyzed what banks performed best on the Russian market from 2004 to 2015 - state, private, or foreign-owned ones. They found out that during stable economic and political periods, foreign-owned banks tend to take the lead, while during a crisis period, such as from 2008 to 2013, state-owned banks outperformed them. The article was published in the  Emerging Markets Finance and Trade journal.

General Schemes of Combining Rules and the Quality Characteristics of Combining

P. 29-38.
Lepskiy A.
Some general schemes and examples of aggregation of two belief functions into a single belief function are considered in this paper. We find some sufficient conditions of change of ignorance when evidences are combined with the help of various rules. It is shown that combining rules can be regarded as pessimistic or optimistic depending on the sign of the change of ignorance after applying.

On the Conflict Measures Agreed with the Combining Rules

The conflict measures induced by the conjunctive and disjunctive combining rules are studied in this paper in the framework of evidence theory. The coherence of conflict measures with combining rules is introduced and studied. In addition, the structure of conjunctive and disjunctive conflict measures is studied in the paper. In particular, it is shown that the metric and entropy components can be distinguished in such measures. Moreover, these components are changed differently after combining of the bodies of evidence.

About Relation between the Measure of Conflict and Decreasing of Ignorance in Theory of Evidence
Lepskiy A. In bk.: Proceedings of the 8th conference of the European Society for Fuzzy Logic and Technology (EUSFLAT-13). Amsterdam; Beijing; P.: Atlantis Press, 2013. P. 355-362.

The conflict measure and index of decreasing of igno-rance in frame of Dempster-Shafer theory are intro-duced. Those functionals are analyzed on the bodies of evidences of special type. It is shown that the great correlation between the bodies of evidence is a sufficient condition of decreasing of ignorance after the applying of combining rule. The relationships between the measure of conflict and the index of decreasing of ignorance in the case of different types of evidences and the application of different combining rules were investigated.

Aggregation of Forecasts and Recommendations of Financial Analysts in the Framework of Evidence Theory
Lepskiy A., Кутынина Е. А. In bk.: Advances in Fuzzy Logic and Technology 2017. Vol. 642. Cham: Springer, 2018. P. 370-381.

The article is dedicated to the method of aggregation of financial analysts’ recommendations in the framework of the evidence theory. This method considered on the example of Russian stock market and the quality of the obtained results was compared with the classical consensus forecast. It is shown that the combination rules, which are widely developed in the theory of evidence, allow aggregating the recommendations of analysts taking into account the historical reliability of information sources, the nature of the taken decisions (pessimism-optimism), the conflict between forecasts and recommendations, etc. In most cases it turned out that, obtained aggregated forecasts are more accurate than consensus forecast.
