Arrow-Debreu state preference approach to derivatives pricing is embedded into decision theoretical framework. Derivatives prices are considered as decision variables. Axiomatic decision theory, concerned with the attitude toward uncertainty and existence of closed in *-weak topology sets of...

Recent discussions on the volatility of agricultural prices have been drawing on factors as low short term elasticities of supply and demand, climatic risk, market uncertainty, central banks monetary policies, trade barriers, biofuel development and, finally, speculation. Much debate has aroused...

Closed sets of finitely-additive probabilities are statistical laws of statistically unstable random phenomena. Decision theory, adapted to such random phenomena, is applied to the problem of valuation of European options. Embedding of the Arrow-Debreu state preference approach to options...

This paper deals with bounded rationality as a way to describe behavior and focuses on the question of how to build such boundedly rational models. The first part is a discussion of the reasons why such models are needed and on the situations in which they can be regarded as more particularly...

[eng] Experimental methods, economics and game theory : "nunc est bibendum ". This paper aims at answering a question about the development of experimental economics : Quis, quid, ubi, quibus auxiliis, cur, quomodo, quando ?. It offers a brief historical account of the emergence of an...

[fre] La rationalité désignatrice des « meilleures » actions à sélectionner, telle que la pensée économique l'a progressivement dégagée, soulève des problèmes considérables dès lors que les avenirs possibles sont caractérisés comme incertains. Cet article montre, après quelques...

[eng] Our paper presents some results of an experimental study comparing the des­criptive power of the Expected Utility (EU) model and of a Rank Dependent Utility (RDU) Model allowing the decision maker to subjectively transform objective pro­babilities. The descriptive power of the EU model...
