We provide a discipline for belief formation through a model of subjective beliefs, in which agents hold strategic beliefs. More precisely, we consider beliefs as a strategic variable that agents can choose (consciously or not) in order to maximize their utility at the equilibrium. These...

In this paper, we show that behavioral features can be obtained at a group level when the individuals of the group are heterogeneous enough. Starting from a standard model of Pareto optimal allocations, with expected utility maximizers but allowing for heterogeneity among individual beliefs, we...

In this paper we analyse the risk attitude of a group of heterogenous agents and we develop a theory of comparative collective risk tolerance. In particular, we characterize how shifts in the distribution of individual levels of risk tolerance affect the representative agent's degree of risk...

This paper presents an equilibrium model in a pure exchange economy when investors have three possible sources of heterogeneity. Investors may dier in their beliefs, in their level of risk aversion and in their time preference rate. We study the impact of investors heterogeneity on the...

: MOISE est une méthodologie de gestion de la connaissance qui comporte une étape de spécification de la connaissance, laquelle distingue la connaissance statique de la connaissance dynamique. Cette étape met en œuvre un langage de représentation de la connaissance graphique (LRC) qui...

Notre société dite société de l'information est en train de laisser la place à une société de la connaissance. La théorie de Shannon a permis de poser un cadre formel pour l'étude de l'information. Le présent papier propose une transposition de cette théorie à l'étude de la...

In this paper, we propose a method to model evolution processes of Knowledge in an organisation. We set the concepts of the methodology and describe the evolution models that will complete the historic point of view of MKSM systemic approach. Our goal is to make mechanisms that lead to...
