For the purpose of determining the influence of the amount of savings circulating in national economy on that economy's growth or drop, a discrete mathematical model with one commodity was developed describing its production as a function of joint investments, depreciation, and introduction of...

Presented here is the disequilibrium model of business fluctuations for quantity and prices, which is based on the Input-Output Model of Wassily Leontief. Disequilibrium states are described by the second-order differential equation system that interrelates commodities' demand, production, and...

Presented here is the mathematical model with one commodity describing the dynamics of the inflationary process. This model is also applied to research how the hypothesis of rational expectations could affect the commodity's demand and production after increasing the amount of money on the market

Presented here is the mathematical model with one commodity binding the commodity's demand, production, consumption, and savings values, and describing the economic system's reaction after increase of commodity's demand on market. It is also shown the formula for optimal behavior of an interest rate
