Cet article constitue la mise au point et le developpement d'une communication anterieure sur le meme sujet. Il concerne le probleme pose par l'incompatibilite de la regle de vente au cout marginal preconisee par les Welfare Economics, et les conditions d'equilibre budgetaire imposees par les Pouvoirs Publics aux entreprises nationalisees. La methode consiste en une de Pareto appliquee a un modele general dont les liaisons de structure comportent a la fois des liaisons entre les quantites et des liaisons entre les valeurs. Les resultats obtenus, rassembles dans la section 8, sont commentes et compares aux solutions anterieurement proposees a ce probleme. Un resume de cet article est constitue par les sections 1, 3, et 8, qui peuvent etre lues sans prendre connaissance des calculs. Le modele developpe dans la section 2 a pour objet de faciliter l'interpretationdonnee dans la section 3, et d'expliquer plus clairement l'intervention des prix et revenus dans les liasons du systeme; mais la maximation exposee dans la section 5 est effectuee sur le modele transforme qui, a la fin de la section 4, rassemble sous une forme condensee les liaisions du systeme. La section 9, enfin, a l'occasion de la critique faite de la politique traditionnelle des monopoles publics, commente certains points particuliers des resultats exposes dans la section 8.

A framework for a static theory of consumer behavior is advanced which will not only subsume the standard indifference curve approach and the technique of preference, but will also admit a more general class of behavior patterns. The proposed theory analyzes consumer behavior from two related aspects, the first being that concerned with the consumer's subjective point of view as to his actions in the market, and the second being concerned with the economist's point of view as an objective observer of the consumer's market behavior. The paper deals with the n-commodity case, and makes no restrictive assumptions as to the regularity of the commodity space, existence of a utility function, continuity of consumption, or non-satiation in taste. In addition to the usual postulates for static analysis, only two behavioral axioms are assumed: (a) a revealed preference transitivity type axiom, and (b) a no-price illusion axiom (somewhat similar to the usual no-money illusion assumption). Demand theorems analogous to those commonly derived in consumer theory are proved by means of a generalized revealed preference approach and by the use of convex set theory in Euclidean n-space.

THIS study attempts to evaluate the importance of some influences on inter-industry changes in average hourly earnings for the period I939 to I947 in manufacturing. We consider the relationships between earnings changes and the original earnings level, changes in production, employment, productivity, the importance of wages in total costs, and the extent of unionization. Our statistical investigation covers 57 manufacturing industries, including all those industries for which Census Bureau output indexes, or combinations of them, comparable to B. L. S. data on hours and earnings were available.'
