Economic substance and evolutionary stages of a liquidity trap

The global financial and economic crisis and its no less essential consequences have become the top challenges of recent years for both researchers in the field of economic theory and practitioners of economic policy. The global crisis renewed interest in the problem of liquid-dity traps, putting on the agenda of scientific discussions such issues as the economic sub-stance of liquidity traps, which many developed countries of the world faced, and the causes of their occurrence.
