Abstrakty

Autorka zwróciła uwagę na ewolucję oceny kształtowania aktywnej polityki pieniężnej w nowoczesnej makroekonomii nurtu neokeynesowskiego. Wskazała na elastyczność obecnego ujęcia tej szkoły, która zaadaptowała do swojej teorii te elementy z dorobku innych kierunków myśli ekonomicznej, które nie podważały jej sposobu interpretacji, świadcząc równocześnie o postępie w ramach keynesowskiego paradygmatu.

Post Keynesian economics was achieving triumphs in practice and theory till the beginning of the 1970s. However, the powerful development of Monetarist and New Classical ideas crowd the Keynesians out the mainstream of economics. Two assumptions, namely the thesis that agents are in a state of continuous equilibrium and rational expectations hypothesis (REH), turned out to be the most dangerous for the Keynesian position. In accordance with those suppositions the economists became dominated by the opinion that monetary policy is ineffective and cannot influence the real variables. Nevertheless, in the mid 1970s Keynesians started to construct models including REH and nominal (price and/or wage) rigidities showing that monetary policy has its stabilizing power after all. It was argued that the New Classical assumption of perfectly elastic prices and wages does not reflect the real circumstances while REH is a very promising idea. Soon it became also obvious that the assumption of rigid prices in models with rational expectations is not a precondition for obtaining the desirable results. The power of monetary policy can be based on uncertainty and the costs of gathering and processing the information. The successful Keynesian response to Monetarist and New Classical counterrevolution was the beginning of New Keynesian economics. Owing to the openness on attainments of opposing economic schools and accommodation ability New Keynesians managed to regain the position lost at the beginning of the 1970s. (original abstract)
