Strategic Behavior in Exhaustive Ballot Voting: What Can We Learn from the FIFA World Cup 2018 and 2022 Host Elections?
Procedures aggregating individual preferences into a collective choice differ in their vulnerability to manipulations. To measure it, one may consider the share of preference profiles where manipulation is possible in the total number of profiles, which is called Nitzan-Kelly's index of manipulability. The problem of manipulability can be considered in different probability models. There are three models based on anonymity and neutrality: impartial culture model (IC), impartial anonymous culture model (IAC), and impartial anonymous and neutral culture model (IANC). In contrast to the first two models, the IANC model, which is based on anonymity and neutrality axioms, has not been widely studied. In addition, there were no attempts to derive the difference of probabilities (such as Nitzan-Kelly's index) in IC and IANC analytically. We solve this problem and show in which cases the upper bound of this difference is high enough, and in which cases it is almost zero. These results enable us to simplify the computation of indices.
High risk of informal behavior during the Olympic Games bid procedure requires some changes in the current system since the subjectivity in choosing the Olympic Games capital, risk of double selling of the votes and other informal behavior still exist.
Game theory is the mathematical discipline aimed to model various interactions of living organisms in quantitative terms. Game theory, as the universal method for the analysis of social interactions has wide applications in economics, in the theory of control and management, financial mathematics, evolutionary biology, sociology, psychology and politics, in modelling different social processes, in particular, the processes of democratic elections, processes of fair distributions of resource, processes of arms control, etc. The book is designed for all wishing to get acquainted with main ideas and methods of game theory.
The first part gives an elementary but systematic exposition of the main ideas of modern game theory without any special prerequisites in mathematics (secondary school level should be quite sufficient). The second part is devoted mostly to the mathematical methods of the theory.
To stimulate mathematical and scientific imagination and to add charm to the book we illustrate it by carefully selected artistic graphics of a world renowned mathematician and mathematics imaging artist A.T. Fomenko (to whom the authors express their deepest gratitude for allowing to use his works in this text). Though these works were originally designed to illustrate the geometric structure of the Universe, they fit nicely in the circle of ideas dealt with here.
For the second edition the book was essentially revised and updated. When preparing the 1st part of our book we aimed at selecting material reflecting the most fundamental part of the theory that we did not expected to become outdate soon. Therefore the first part remained mostly unchanged (with couple of new insightful examples added). On the other hand, for the second part, apart from correcting typos, lots of new material was prepared. In particular, Chapter 10 was essentially enlarged by more recent developments on game-theoretic treatment of option pricing and two completely new chapters were written: Chapter 12 on games with many agents analysed via the statistical limit of infinite number of players, and Chapter 13 on quantum games. These two topics represent arguably the most bright new trends in the 21 st century game theory. Due to strong physics input, the theory of quantum games still remains separated from the main stream of game theory, and our exposition is possibly the first appearance of quantum games in a mathematics textbook.
The article is devoted to the development of the principles of communicative strategies typology construction which is considered to be a method of scientific research of individuals' communicative interaction.
Conference Proceedings report findings presented at the 20th Annual Conference of the National Association of Teachers of English in Russia held in Voronezh in April, 2014. The proceedings might be useful for English language teachersworking at different levels - from University to kindergarten. linguists, interpreters and translators, as well as students and postgraduates majoring in EFL, linguistics and cultural studies.
Two studies investigated reciprocal effects of values and voting. Study 1 measured adults’ basic values and core political values both before (n=1379) and following (n=1030) the 2006 Italian national election. Both types of values predicted voting. Voting choice influenced subsequent core political values but not basic values. The political values of free enterprise, civil liberties, equality, law and order, military intervention, and accepting immigrants changed to become more compatible with the ideology of the chosen coalition. Study 2 measured core political values before (n=697) and following (n=506) the 2008 Italian national election. It largely replicated the reciprocal effects of voting and political values of Study 1. In addition, it demonstrated that left-right ideology mediated the reciprocal effects of voting and political values. Moreover, voter certainty moderated these effects. Political values predicted vote choice more weakly among undecided than decided voters, but voting choice led to more value change among undecided voters.
The author believes that today propaganda is a two way mechanism of communication. In addition to imposing and informational pressure, it involves the formation of public opinion on the basis of awareness of the benefits of the proposed policy for the society. Propaganda is not only a tool of ideology, but also an independent element in the overall structure of the ideological system, especially in conditions of Soviet "idiocracy". Therefore all attempts of Western political science and sociology to separate propaganda and education do not work on the example of Soviet reality.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.
The paper studies a problem of optimal insurer’s choice of a risk-sharing policy in a dynamic risk model, so-called Cramer-Lundberg process, over infinite time interval. Additional constraints are imposed on residual risks of insureds: on mean value or with probability one. An optimal control problem of minimizing a functional of the form of variation coefficient is solved. We show that: in the first case the optimum is achieved at stop loss insurance policies, in the second case the optimal insurance is a combination of stop loss and deductible policies. It is proved that the obtained results can be easily applied to problems with other optimization criteria: maximization of long-run utility and minimization of probability of a deviation from mean trajectory.
