These two volumes bring together a set of important essays that represent a "new Keynesian" perspective in economics today. This recent work shows how the Keynesian approach to economic fluctuations can be supported by rigorous microeconomic models of economic behavior. The essays are grouped in...

Macroeconomists have largely converged on method, model design, reduced-form shocks, and principles of policy advice. Our main disagreements today are about implementing the methodology. Some think New Keynesian models are ready to be used for quarter-to-quarter quantitative policy advice. We do...

In this symposium I shall play the role in which I was cast, the unreconstructed old Keynesian. Considering the alternatives, I do not mind being billed as a Keynesian, an old Keynesian at that. But old Keynesians come in several varieties, and I speak for no one but myself. Nor do I defend the...

The new Keynesians made more rapid progress in understanding the microeconomics of unemployment than in understanding the microeconomics of nominal price rigidity. But the past five years have seen important breakthroughs in this second area. This paper will describe these breakthroughs, discuss...

Changes in both the macroeconomy and in macroeconomics suggest that the IS-LM-AS model is no longer the best baseline model of short-run fluctuations for teaching and policy analysis. This paper presents an alternative model that replaces the assumption that the central bank targets the money...

The IS-LM model has no greater prospect of being a viable analytical vehicle for macroeconomics in the 1990s than the Ford Pinto has of being a sporty, reliable car for the 1990s. Because of its treatment of expectations, the IS-LM model, as traditionally constructed and currently used, is a...

The theoretical and empirical international trade literature suggests that there is long-term valuation/devaluation of the real exchange rate in the developed/undeveloped economies. We argue that the real exchange rate is affected by: i) intercountry differentials of the services sector...

The objective of this article is to present the structure and the first computational simulations of a one-sector macrodynamic model that imbed some elements of the post- keynesian theoretical framework. The theoretical elements embed in the model are: i) determination of the level of output by...

It is developed a dynamic macromodel of utilization and growth of productive capacity, in which the supply of credit-money is endogenous and firms' debt position - and thus the financial fragility of the economy à la Hyman Minsky - is explicitly modeled. The rate of interest is set as a markup...

The paper presents a post-keynesian growth model in which (i) the mark-up rate varies in the long-term due to a misalignment between the actual rate and the 'desired' profit rate; and (ii) the capital-output ratio is not necessarily constant, on the contrary it may shift as a result of the...
