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...

Theories of justice in the spirit of Rawls and Harsanyi argue that fair-minded people should aspire to make choices for society as if in the original position, that is, behind a veil of ignorance that prevents them from knowing their own social positions. In this paper, we provide a fairly...

This paper argues that mainstream economic the- ory, far from providing an indisputable plea in favor of shareholder value-maximization, o ers striking arguments showing quite the opposite: pro t maximization cannot be a legitimate prioritar- ian goal for private rms. This opens the door for a...

This paper provides a new framework for monetary macro-policy, where the Central Bank potentially intervenes both on short-term and long-term loans markets, and can do this alternatively by manipulating interest rates or money supply. Following Bonnisseau and Orntangar (2010) and Giraud and...

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...

Extractive industries face two main challenges in terms of CSR and poverty reduction: 1) recognize that societal activity is part of their core business; 2) take part in socio-economic projects that contribute to their stakeholders' empowerment and not only to their living conditions. Based on...

This paper argues that mainstream economic theory, far from providing an indisputable plea in favor of shareholder value-maximization, offers striking arguments showing quite the opposite : profit-maximization cannot be a legitimate goal for private firms. This opens the door for a widening of a...
