[fre] Monopole discriminant et redistribution. Une interprétation des thèses d'Edgeworth. . Outre sa théorie du noyau, sa conception de la justice sociale, Edgeworth (1845-1926) a élaboré, à partir des travaux de Dupuit, une vision du monopole et de la concurrence imparfaite aussi...

SHARKEY & SIBLEY [1993] ont démontré la soutenabilité de tous les optima redistributifs dans un cadre de tarification binôme optionnel. Les résultats présentés dans ce papier montrent que leurs conclusions ne sont pas toujours valides en tarification non linéaire. Après la présentation...

This note analyzes some properties of optional two-part pricing in a two-type economy. First, the optimal contracts along the Paretian frontier are described. Then, the duality relation between the Rawlsian program and the discriminating monopoly is demonstrated. Last, this property is used to...

In a partial equilibrium framework, SHARKEY and SIBLEY [1993] show paradoxally that all redistributive optimal two-part pricings are sustainable. They also suggest the extension of their main result to non-linear pricing. In this paper, it is shown that in fact their result doesn't extend...

In several papers, Negishi revisted the foundations of competitition. Sensitive to the Edgeworthian views of exchange but strongly influenced by the law of indifference of Jevons, he tried to reconcile both approaches. The main result of this synthesis is the equivalence between the walrasian...
