L'hyper-croissance est un phénomène perturbateur pour la PME : les exigences de rentabilité sont fortes et les équilibres financiers sont fragiles. Malgré les potentiels de croissance, les sources de défaillance sont nombreuses. Une analyse comparative d'indicateurs financiers nous permet...

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...

Victor prefers safety more than Ursula if whenever Ursula prefers some constant to some uncertain act, so does Victor. This paradigm, whose Expected Utility version takes the form of Arrow & Pratt's more risk averse concept, will be studied in the Choquet Uncertainty model, letting u and μ (v...

We propose an ethical viewpoint based on the possibility of the realization of the worst-case scenario in order to reduce future generations risks in terms of discounting. Applied to the question of conservation of a renewable resource, we show that an economy, where the social planner takes...

We provide a general theorem on the aggregation of preferences under uncertainty. We study, in the Anscombe-Aumann setting a wide class of preferences, that includes most known models of decision under uncertainty (and state-dependent versions of these models). We prove that aggregation is...

This paper applies to adverse selection theory the advances made in the field of ambiguity theory. It shows that i) a relevant second-best contract induces no production distortion considering the efficient agent as in the standard case. But the principal has to pay a higher information rent...
