The book "Economic Theory and the Experience of Development in the USSR and Russia" offers a comprehensive analysis of the economic mechanisms that shaped the growth and development of the Soviet Union and Russia after 1950. Written by Hungarian economist D'jordy Shimona-mladshego, the monograph is based on the Kaldorian approach and addresses central themes such as production, equilibrium prices, income distribution, profit formation, wages, and capital accumulation. The developed models allow for a nuanced examination of economic development and clearly distinguish themselves from the assumptions of classical and neoclassical economics. The book is aimed at a broad audience interested in political economy, economic theory, and its practical application.
