Abstract

The article continues a publication with the same title and outlines the development of the economic theory during the 20th century. The review of the evolution of the neoclassical school ends with the study on the emergence and development of modern macroeconomics. Special attention is put on the newest trends in macroeconomics from the last quarter of the 20th century. The non-orthodox economic schools - institutionalism and marxism and their evolution during the century are studied. It is pointed out that although at the end of the century the pluralism of economic ideas is preserved, there is a clear trend of growing interaction and infiltration among the main theoretical schools, which will have an important influence on the nature of the economic theory in the future.
