The paper is a brief account of Georges-Théodule Guilbaud?s (1912-2006) contributions to contemporary aggregative theories. An unnoticed precursor, Guilbaud anticipated on the algebraic conception of aggregation and on the more recent judgment aggregation theory, which generalizes social...

This paper analyzes how economic history and cliometrics can improve our understanding of the financial crises. We discuss the contributions of authors like Reinhart and Rogoff, Bordo and Eichengreen. According to Reinhart and Rogoff the recent crisis is similar in many aspects to former...

Hayek regards complexity as specific to spontaneous orders or self-organizing structures. These orders are characterized by the phenomena of irreducible ignorance and emergence (of new properties of the whole which its separate parts do not possess) and by the incapacity to handle them. Their...

J.S. Mill is generally considered to be the theorist who gave birth to the concept of natural monopoly in its modern sense. Yet, no author has specified that Mill distinguishes two types of monopoly, the ?natural monopoly? and the ?practical monopoly?. I show that Mill?s notion of ?practical...

This article analyses Maurice Allais?'s contribution to the study of the stability of a competitive equilibrium. In his Traité d?'économie pure [1943], he demonstrates the local stability of a walrasian economy under a set of hypothesis tantamount to gross substitutability (Negishi [1962])....
