Have the early coordination failures models achieved Keynesâ€™s programme ?
The aim of this paper is to assess how three seminal coordination failure models (Diamond ((1982)1991), Howitt (1985) and Roberts (1987) have fared against â€˜Keynesâ€™s programmeâ€™. The first part of the paper characterises Keyneâ€™s programme as consisting of the following four objectives : (a) demonstrating the existence of involuntary unemployment, (b) demonstrating that wage rigidity can be exonerated as its cause, (c) giving a general equilibrium interdependency explanation of the phenomenon within a perfect competition framework, ad (d) demonstrating that demand stimulation is the proper remedy to suppress involuntary unemployment. In a second part, I claim that no correct assessment of Keynesâ€™s programme can be made without drawing a distinction between involuntary unemployment and underemployment. These prerequisites being settled, in part three I undertake the study of the three models to conclude that none of them succeed in achieving Keynes â€˜ programme in its entirety. In the last part of the paper, I raise the issue as to whether Keynesian economists should continue to fight for the involuntary unemployment concept.
