Abstract

An attempt was made to evaluate entirely and objectively Keynes’ place in economics, his extraordinary approaches and views on: the crucial role of investments in relation to savings under the conditions of crises and stagnation in economy; the major significance of the fiscal policy as an instrument of macroeconomic regulation; the inefficient cut of government expenditure under depression; the moderate conservative nature of his social philosophy. The evolution of the main Keynesian Schools and trends is monitored – New Keynesians, Post Keynesians in two versions (the English Cambridge School and the American Monetary System), the Non-Equilibrium analysis and New Keynesians.
