The aim of Bernard Schmitt’s analysis of the monetary economy of production was twofold: to introduce and to explain the logical character of the macroeconomic laws governing our economies and to explain the origin of the pathologies that follow if these laws are not complied with. Schmitt’s main original contributions concern the theories of value, profit, and capital, as well as his explanation of inflation, unemployment and international payments, unified as quantum macroeconomic analysis. This book expounds on the key principles of quantum macroeconomic analysis as he conceived and developed them.Schmitt’s starting point was the analysis of bank money and the way it is associated with produced output. His macroeconomics was not founded on microeconomics nor derived from the aggregation of microeconomic variables. Schmitt’s theory does not rely on mathematics and modelling either; instead, it is based on logical laws derived from the nature of money and monetary payments. Part I of this book deals with the quantum macroeconomic analysis of capitalism and its pathologies developed by Schmitt and provides the elements necessary to understand its ‘structural’ mechanism. Parts II and III deal with the principles of two reforms that enable the passage from capitalism to post-capitalism and from the present non-system of international payments to an orderly system. This book provides essential reading for all those interested in heterodox approaches to macroeconomics, monetary economics, banking, international economics, and the history of economic thought.
