DIFFERENTIATION, EFFICIENCY AND INFLATION IN ECONOMIC THEORY

The paper proposes four parameters to measure the efficiency of investments and their inflation. These parameters were calculated for relatively large 49 countries with a fairly advanced level of economic development separately, and for the rest of the world within the framework of 3 international economic associations (OECD, Old EU countries and New EU countries) and the World (as a whole) for two-time ranges (1996–2008) and (2009–2023). Based on the calculated parameters, ratings of the efficiency of investments and broad money supply (M3 aggregate) and their inflation for these 53 subjects, which include all countries of the world, are constructed. The necessary conditions for ensuring the growth rate of GDP of modern Russia above the world average while maintaining macroeconomic stability are shown.
