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 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...

Presented here is a simplified mathematical model describing a supply side crisis caused by the coronavirus pandemic (COVID – 19). Model of a single-product economy is presented where the supply shock has a constant acceleration. If amount of the supply shock has a modest positive acceleration...

Paper introduces mathematical models describing long-time effects of real savings on economic growth. Models are built for single-product and multiple-product economy with market forces presented through the system of ordinary differential equations. Modeling results show a limited long-run...
