While the meaningful theorems of neo-classical theory of the producer are well known, the neo-keynesian counterparts are not. Therefore, this paper will present those new meaningful theorems and their relations with neo-classical theory. On the one hand, this paper is of interest to the...

When some necessary Walrasian conditions are eliminated, a differentiable manifold is obtained. Here, it is called the Patinkin-Malinvaud manifold since our device to define it amounts to recover the methodology of these authors. Such a methodology is sufficient to contain in the same logical...

The paper is divided into two parts. In the first one, three complete systems of demand equations are derived, namely, the standard neo-classical model, a model under quantity rationing and the general reduced form of walrasian models. The standard neo-classical model has no spillover eflects...

This paper contains a discussion on three contributions done by Maurice Allais which are largely unknow. We present his conception on microeconomic dynamics (it is still revolutionary), his characterization of substitution and complementarity (it is still original) and finally, the links between...

The purpose of this paper is to integrate into a general model of an open economy the study of optimal wedges on domestic and foreign transactions.

After greeting the recent propositions of the E.C.C.'s Report ("Au-delà des frontières") as a potentially useful document to encourage discussions on the efficiency of our institutions, the reviewer recasts them in a first best framework, a second best one and a socio-cultural one. By any...
