Modelling of Non-Commuting Measurements

 

In the paper we propose an approach which allows to discuss on formal level non-commuting measurements. Such measurements 'disturb' a measured system and change its states. The key structure used in the description of such measurements is the structure of ortho-poset (which is a Boolean lattice in the classical case of commuting measurements). States of the system are realized as probabilistic measures on the ortho-poset. We give an application of the proposed approach to decision-making under 'non-classical' indeterminacy and to modelling 'non-classical' preferences.

Evaluating the Degree of Manipulability of Certain Aggregation Procedures under Multiple Choices


The authors would like to thank A.A. Zaslavskii and the anonymous referee for useful remarks.

The work of F. Aleskerov and D. Karabekyan was supported in part by Scientific Foundation of SU HSE, project no. 08-04-0008 and the Russian Foundation for Basic Research, project no. 08-01-00039a. The work of V. Yakuba was supported in part by the Russian Foundation for Basic Research, project no. 08-01-00039a.

The problem of manipulation in voting is studied in the case of multi-valued choice. Well-known and new schemes of preferences extension enabling one to compare all possible social choices under an arbitrary number of alternatives are presented. The known indices of degree and efficiency of manipulation are described, and new indices are introduced. These preference extension schemes and indices are used for computer-aided evaluation of the degree and efficiency of manipulation of the known voting procedures allowing multi-valued choices. The results obtained are presented for five voting rules.

Economies with Asymmetrically Informed Agents: the Concept of Limit Information

 

The research has been supported by the Council for Grants (under RF President) and State Aid of Fundamental Science Schools grant SS-4113.2008.6.

In this paper, a new concept of "limit information" is introduced and studied for Arrow-Debreu type economies with asymmetrically informed agents. The concept is based on the so-called contractual approach that presumes that agents meet and form coalitions, where the concurrent exchange of commodities and information is realized. So, in the course of a natural exchange process, the agents' information is repeatedly transformed and accumulated, and agents learn and achieve limit information. It is proved that, for a monotone information sharing rule, limit information is unique, i.e., it does not depend of the chain of coalitions implemented in the process of interaction between economic agents.

Ratings as Measure of Financial Risk: Evolution, Function and Usage

 

The rating agencies were emerged by the demand from market economy. Such agencies take the job of independent evaluation of the firms' financial strength, which allow firms decrease their expenses on their own market monitoring. It is extremely important with increasing number of potential business partners.

The paper discusses history of rating business, methods of assigning ratings, rating classification, function and the directions of use.

Analysis of the Relationship Between the Exchange Rate Policy of the Russian Central Bank and the Interest Rates: Uncovered and Covered Parity


An important condition for the transition to the free float and inflation targeting regime is the ability of the Russian Central Bank to pursue an active independent policy of interest rate adjustment. The purpose of this investigation is to analyze the effect produced by the exchange rate policy of the Russian Central Bank on the money market and to assess the sensitivity of domestic interest rates to foreign rates through the covered and uncovered interest rate parities. Assessment of variations in the coefficients of the tested relationships at different stages of the Russian Central Bank's exchange rate policy will allow judging the success of the institutional development which prepares a gradual transition to free float and inflation targeting.

Is Gas Cartel's Profitable for Russia? (A Case of European Gas Market)

 

The problem of gas cartel formation is widely discussed in many countries, including Russia. Gas cartel can exist only within the world natural gas market, the latter being possible provided liquefied natural gas (LNG) becomes wide spread. Since for Russia, European gas market is of prime importance the paper analyses perspectives of gas cartel, relative to the European market. Equilibrium states of such a market have been found for the two cases - that of a competitive behavior of LNG exporters to Europe, and of gas cartel which includes Russia and LNG exporters. Conditions ensuring that Russia gets higher profit in case of participating in a gas cartel, rather than in case of competitive behavior of LNG exporters, have been obtained.

Paradoxical Behavior of Production Sharing Participant

 

We consider a mining or other extractive project, which is fulfilled on the basis of a production-sharing agreement. These agreements provide for production sharing on the basis of current IRR or current R-factor. The implications of using such production sharing mechanisms are studied with the help of simple economic-mathematical models. It appears that in some cases these mechanisms stimulate paradoxical behavior of the investor. For example,  those variants of a project which require higher investments but return same yields happen to be more advantageous to the investor; and similar are those variants which provide smaller yields with the same investments.
