Season Fluctuations Separation on the Basis of Variational Principles
A distribution-free procedure for separating "season waves" (cycles) from arbitrary time series based on variational principles is considered. In its initial statement, the problem is not correct in Tikhonov's sense. A regularization suggested separates a class of solutions for which the problem becomes correct. It is shown that the existence of singularities in the initial realization leads to trend "noising". The preciseness of "season wave" restoration depending on series parameters is estimated. Numerical results for model series and a number of macroeconomic indices are presented.

Econometric Cross-Impact Analysis of Share Prices in Stock Market Technological Sector
In the article, a method of identification of statistical, causal relationships between share prices and stock market indices as a tool for their forecasting is considered. As a statistical base of calculations, series of daily quotations for 1991-1999 for some major companies and of stock indices are used. To evaluate the influence. Granger's test is applied. It is shown that the application of this approach is especially advisable when a great number of market participants is considered and it is necessary, first of all, to establish the fact itself of the existence of causal relationship. In this case, the method suggested makes it possible to identify market leaders and to essentially narrow the domain of possible regressors search in a more detailed statistical analysis.

The equilibrium transfer prices under vertical interaction
of production economic agents
The author considers the relations between the supplier's and the consumer's net profit and amount of transfer, rate for intra-group transactions and own circulating assets. The values of the transfer price mechanism parameters are determined for which total production agents' profit is maximum. Formulae are obtained to calculate .rates for intra-group transactions and transfer for which the supplier and the consumer have positive net profit increments in relation to its maximum value in the case of using market prices. It is proved that transfer prices effects for the supplier, the customer and the state are positive for any relationships between own means of production agents and their needs of circulating assets when the financial market is well developed and for a solvent supplier and/or when the consumer's funds are insufficient in the case of a non-developed financial market. A model of equilibrium transfer price mechanism is proposed. It is shown that the equilibrium set is the set of optimal - by the total net profit maximization criterion - agents; states with rates for intra-group transactions providing non-negative effects for the supplier and the consumer. When using the equilibrium mechanism of transfer prices and reinvesting profit, the agents function on a stationary trajectory and it gives total net profit, equal - ceteris paribus - to maximum net profit of a vertically integrated firm consisting of these agents.

Interindustry balance mathematical models under a dispersed market
The author considers mathematical models of a multi-product market consisting of interlocking dispersed markets. The static model describes a multi-product market in an equilibrium state. Methods of searching for an equilibrium state based on mathematical methods of hydraulic circuits are proposed. The dynamic model of a dispersed market is a sequence of its interlocked equilibrium states. The model allows - with taking into account consumption of irreproducible resources - to forecast the development of market subjects over time, to simulate competition among them and governing impacts on the system to regulate market relations.

A modified Braun method for solution of a "non-classic"-type matrix game
Diversity of decision-makers' preferences in economic problems has engendered diversity of decision-making criteria under uncertainty. Application of a number of criteria in forming a conflict situation model leads to changing the structure of traditional models which entails the impossibility of direct application of well-known iterative procedures to obtain the solution. A modification of the method proposed by Braun is considered for solving a mixed extension of matrix games with the purpose of its generalization for a wider class of problems. The connection of this approach with game processes of a more general type is shown.

Dynamic efficiency of the equilibrium transfer prices mechanism
The object of investigation is the path of a supplier and a consumer functioning when they use the mechanism of equilibrium transfer prices and reinvest profits. Formulas have been obtained to calculate the parameters of the equilibrium state. It is shown that the strategically optimal is the equilibrium path under the maximum permissible transfer rate. Under holding, where the permissible value of such a rate can be larger, the agents' total net discounted income is increased in relation to the variant of equilibrium path under economically independent enterprises vertical interaction.

Problems of regulating economic growth in macroeconomic models
The author considers the evolution of theory of economic growth from the Harrod-Domar model to the "new neoclassical wave". It is shown that within the framework of the neoclassical theory (including taking into account endogenous scientific and technical progress too) there is no reallocation of means among production factors through which long-term growth could be achieved the rate of which were not be determined by an extensive factor - the growth rate of volumes of labor used. Possibilities are studied of modeling economic growth at the expense of the innovation component of development within the framework of the new neoclassical school. A model of production function is suggested, taking in account the relationship between accumulated volume of technological knowledge, efficiency of labor and structure of fixed capital. Interrelationship is shown of this approach with those of the former and the "new" neoclassical theory. For the class of models in question, factors of economic growth based on innovations are studied and possibilities of realizing these factors are analyzed.

The gross substitutability property for piecewise linear
The article deals with studying the gross substitutability property of demand generated by utilities, quasi-linear with respect to money. For piecewise functions the gross substitutability property is easily expressed in terms of the function tesselation. With the use of this criterion, it is shown that the gross substitutability emplies submodularity of the utility function and is equivalent to supermodularity of the Fenchel-conjugate function.

Model research of corruption under privatization
The author studies a closed equilibrium model of corruption under privatization. Unlike models described earlier (see , ), the scale coefficient of penalty functions acts as an endogenous variable, determined from the condition of sum of bribes minimization. To organize bribe revealing checks, a fixed amount of money is assigned and all additional expenditures connected with conducting these checks are covered at the expense of penalties. The existence of stable equilibrium with minimum corruption level is established and its properties are described.
