Model for Regulating the Reproduction Process in the Economy

The authors analyze the regulation of the reproduction process in the real and financial sectors of the economy by variations in the amount of cash in circulation and through the investment policy of the state, as well as the consequences of the collapse of the market value of securities. The production sphere is shown to unite the production system (production), banking system, market system, domestic households, and the rest of the world. It is shown that the regulators of the economic reproduction are the banking system that provides credits to production and the necessary amount and velocity of money in the real sector, the financial sector that is selling securities for cash and investing in production, and the state that pursues an investment policy for the expanded reproduction of production capital. The reproduction process of the economy of Ukraine is modeled for 2022–2024 by the statistical data of 2020 and 2021.
