Abstract

We attempt to make a comparative evaluation of modern
macroeconomic schools: Monetarism and New Classical School based on the
Classical System that
envisage automatic full employment or natural rate of unemployment (NRU)
equilibrium (AFNE or ANRUE) vs. New Keynesian and PostKeynesian Economics based
on the Keynesian System which gives unemployment equilibrium (UNE) or
non-automatic NRU equilibrium (NANRUE) due to insufficiency of aggregate
demand. In order to determine which school is relevant, first the basic
assumptions of these systems are compared: i) rational vs. adjusted vs.
heterogeneous expectations, ii) existence of perfect competition in all markets
leading to flexibility of prices and wages vs. imperfect competition giving
rise to rigidities, and iii) presence or lack of coordination between markets.
In the final phase of our evaluations the performance of the developed
economies are surveyed to establish whether we meet with AFNE or ANRUE or else
UNE or NANRUE; and whether policy prescriptions devised by respective schools
solve or alleviate the problem at hand when implemented. Our investigations
point out that New Keynesian and Post-Keynesian schools are more relevant
compared to Monetarism and New Classical School. The choice between New Keynesian
and Post-Keynesian Economics, however, is more difficult to make although New
Keynesian Economics seems more widespread than Post-Keynesian Economics.
Objectively, Post-Keynesian assumptions seem more realistic; normatively,
however, New Keynesian stands seems more fit to the present day move towards
globalization.
