An optimal relationship between taxes, currency issue and loans in the Sydravsky model with external loans
An optimal fiscal and monetary policy of government when maximizing the consumer welfare function is investigated as exemplified with the Sydravskii dynamic model with external loans. Weighty initial debts identify an optimal scheme with a certain relationship between income tax rate and face interest (inflation rate) at a Felse relationship type. The range of face interest rate is adjusted. It is shown that under certain conditions income tax and inflation rate grow when raising the initial debt charge and decrease when the latter decreases. A threshold rule for determining the inflation sign depending on the debt charge is provided.

A stochastic model of "sight" deposits amount dynamics
One of the important sources of commercial banks means accumulation are so-called "sight deposits", the main feature of which is the opportunity of their almost instant withdrawal from the bank. The deposits of such type relate to the risky bank resources (see e.g. [1-4]). Thus greatly actual becomes the problem of mathematical modeling dynamics of amounts as separate "sight" deposits, as well as the aggregate amoumt of the whole bank resources of such type. A modification of stochastic multiplication models of deposits amount dynamics [1, 5, 6] is given with taking into account the uncertainty of depositor behavior and using some schemes of reliability theory and queuing theory, which became widespread when studying complex economic processes of different nature.

Gross substitutability and comparative multivalued demand statics
in markets with friction: the hicks's law and the paradoxes of taxation
The authors consider a general equilibrium model of a system of markets with "friction" (taxes, tariffs, transaction costs, buying and selling bans). Sufficient conditions have been found - in terms of initial parameters - of the gross substitutability property fulfillment, Walras's law, as well as conditions imposed on the model parameters and price domain under which the demand mapping is subject to Hicks's law. In this case, under certain additional conditions, the dependence of price of any good on tax on it or on its stock turns out to be monotone nonincreasing mapping. The authors have also built "paradoxical" examples of growth of volumes of trade and of utilities owing to raising taxes.

Ruble exchange rate as a result of money issue, foreign trade and wandering financial flows
The author suggests a theoretical model of foreign trade and exchange rate that includes a utility function for the country and two balances of expenditure of internal and external currencies. Maximization of the utility function subject to two existing constraints allows determining analytical relations for exports and imports, internal prices, exchange rate, purchasing power parity (PPP). On the basis of the theoretical model formulae and available statistical data, regressions are built for, exports, imports and ruble exchange rate. The regression coefficients are estimated from Russian statistical series for 1996-1999 (including the point of August 1998). To analyze relationship of the catastrophe in 1998 with the GKO-OFZ pyramid, a guaranteed rate is used, i.e. the ratio of "quick money" volume to gold-and-hard currency reserves.

Modeling aggregation mechanism of participants' priorities in the enterprise's
A model is suggested of mechanism of coordinating and aggregating priorities of the organization's decision-making system participants. A general description has been obtained of multi-factor functions representing such mechanisms. Natural indicators have been developed of relative "force" of each of coordination process participants. It is shown that the requirements of action flexibility and universality of such mechanisms (when complying with some natural conditions imposed on these mechanisms) are inconsistent.

Functional properties of institutional traps
Conditions are f9rmulated under which an economic system cannot get out of a sosalled institutional trap. Conditions are based on taking into account transaction and transformation costs. It is shown that in a hufflber of cases, an exit from an ineffective state can only be on a path of sufficiently intensive economic growth and this explains the stability of many traps in the recessive Russian economy. It is proven that when using mixed institutional strategies by economic subjects which assume activities within both the old and the new norms simultaneously, the economy tends to a production recession mode Computations carried out have confirmed that institutional traps are not a fatal phenomenon of economies under reforms and it is possible to get rid of them when incurring quite moderate transformation costs.

On one approach to taking into account the influence of uncertainty and risk upon investment project efficiency
One pf possible ways of using capital-forming investment projects (IPs), Value at Risk (VaR) indicator, is specified. It is widely used lately for financial investment risk evaluation. The desirability of such approach is based on those shortcomings that, in the author's opinion, are incident to attempts to take into account any IP risk (independently of its character and origin) by introduction of risk premium in the discount rate. In advance, a brief description is given of indicators of "NFV type" that, in the author's opinion, are more adequate to today's economic realities of the Russian economy than NPV.

The influence of uncertainty on the nation debt structure
A discrete dynamic model of nation debt management with a finite horizon and a wide class of functions of losses from distorting taxation is discussed. Within the framework of a two-pejriod variant of the model, it is shown that growth of real interest rate leads to increase in total debt and decrease in the level of losses at the expense of the use by the authorities of the natural information advantage arising when issuing a nation debt. For the multi-period variant of the model, such effects are maintained only in respect to two last planning periods.
