Mathematical modeling of macroeconomic indicators and its impact on the development of economic policy measures

The crisis state of the modern Russian economy, caused by powerful anti-Russian sanctions of Western countries, requires the intensification of economic policy. The article shows that its theoretical postulates, based on the findings of modern economic science, are not always fair. Conducted quantitative modeling of the mutual dynamics of inflation and unemployment in Russia for the period 2010-2021. refutes the existence of an inverse relationship between these indicators. That is, the traditional Phillips curve in the modern Russian economy cannot adequately describe the situation. A more critical approach is needed to the application of those "common economic truths" that are set out in the educational literature and are familiar to any qualified economist. Life is richer than any theory, and the theory must be tested in practice by carrying out quantitative calculations and modeling real economic indicators.
