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 individually for 49 relatively large countries with a fairly advanced level of economic development, for the rest of the world within three international economic associations (OECD, Old EU countries, and New EU countries), and for the world (as a whole) in 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 are constructed for these 53 subjects, which include all countries of the world. The necessary conditions for ensuring GDP growth in modern Russia above the global average while maintaining macroeconomic stability are shown.
