DlSAGGREGATION, DISEQUlLlBRIUM AND THE NEW CLASSICAL MODEL

Abstract

This paper estimates a disaggregated disequilibrium goods market model with rational expectations for the U.S.A. Both the new classical equilibrium model and the alternative Keynesian model with sluggish price adjustment are nested within this approach. Therefore likelihood ratio tests are used to evaluate them. Estimates for 1946-1989 show that the U.S. goods market is a disequilibrium market and the parameter measuring the variability of excess demand across the markets is well determined.
