This paper outlines what are the essential features of the theory of the monetary circuit. It provides both theoretical and historical foundations to this approach and contrasts it with alternative conceptions of money, including the neoclassical and other heterodox approaches (in particular,...

This document contains three texts. The first one discusses Capital Theory, the second one discusses Keynes achievements and the third one its General Theory of Employment, Interest and Money.

This article explains how movements in the unemployment rate reflect the relative rates of growth of employment and the labour force and are related to the participation rate, labour productivity growth and output growth. A framework is provided in which to analyse the determinants of movements...

The Fisher equation predicts that nominal interest rates and inflation should move together one-for-one. Recently published work argues that both nominal interest rates and inflation are non-linear. The evidence in this paper suggests that nominal interest rates are well described as two-regime...

We establish necessary conditions of optimality for problems of optimal control Theory in the discrete time framework with infinite horizon. Our necessary conditions are in the form of Pontryagin principles. We treat smooth and partially nonsmooth settings, without concavity. A strong motivation...

This paper addresses various attempts by so-called new Keynesians, writing mainly in the 1980s and 1990s, to strengthen the analytical basis, in particular the microeconomic foundations, of these assertions. What, exactly, have then the new Keynesians accomplished, and how should their...

This paper compares two alternative theories of Aggregate supply, both with a "New Keynesian Flavor". The first assumes that prices are rigis due to the existence of menu costs of the kind advanced by Mankiw [38] and Akerlof and Yellen [2]. The second derives price stickiness endogenously as one...

Money has always been something of an embarrassment to economic theory. Everyone agrees that it is important; indeed, much of macroeconomic policy discussion makes no sense without reference to money. Yet, for the most part, theory fails to provide a good account for it. Indeed in the...
