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 that includes differential equations relating the commodity's production, consumption, and price values. Shown are conditions for the fluctuations of these values

Presented here is 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 a simplified mathematical model to reflect a weak recovery after the financial crisis. The model confirms hypothesis that the weak recovery is caused by a decline in investment not compensated by the interest rate decrease. The model explains a transformation of economic trend...
