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 object of this paper is twofold: 1) to introduce the disaggregated legal tax rates into a macroeconometric model containing disaggregated marginal propensities to consume; 2) to simulate variations of tax rates in order to study the relative efficiency of individual tax rates for economic...

We introduce a general to specific approach suitable for panel data. We are led to perform singular value decompositions based on a multivariate variance analysis equation, in which the individual and time effects are explicitely taken into account. This methodology is applied to the analysis of...
