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.

Here author made an attempt to extend the Continuous-Time Model of Business Fluctuations on the space domain. Research methodology is based on Time-Space Model of Wave Propagation developed by author to describe fluctuation processes in physics.

Presented here the mathematical model with one commodity that describes the acceleration of commodity production as a linear function of commodity's deficit on market. The solution of derived differential equation gives the required fluctuations of the commodity's production.

Presented here is the economical model with one commodity that is produced by two independent business entities. Investigated is the mutual impact of entities on each other, and formally described is the dynamics of competitive behavior. The research techniques and results are based on the...

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...

Presented here is the mathematical model of business fluctuations, which can be observed in the Economy described by the Input-Output Model of Wassily Leontief. These fluctuations are obtained as a solution of the corresponding matrix differential equations, which interrelate commodities'...
