We consider a differential information economy with infinitely many commodities and analyze the veto power of the grand coalition with respect the ability of blocking non-Walrasian expectations equilibrium allocations. We provide two different Walrasian expectations equilibrium equivalence...

We study upper semi-continuity of the private and coarse core and the Walrasian expectations equilibrium correspondences for economies with differential information, with Boylan (1971) topology on agents’ information fields. Copyright Springer-Verlag Berlin/Heidelberg 2005

We consider the problem of optimal risk sharing of some given total risk between two economic agents characterized by law-invariant monetary utility functions or equivalently, law-invariant risk measures. We first prove existence of an optimal risk sharing allocation which is in addition...

Cet article compare les modèles unitaire et collectif sur la base de données collectives simulées en présence de divers types de taxation des revenus. Nous distinguons en particulier un système d’imposition individuelle et un système d’imposition jointe. En spécifiant un modèle...

This paper compares collective and unitary models on the basis of simulated collective data with income taxation. We distinguish the cases of individual and joint taxation. Estimating a flexible unitary model, we obtain strikingly different “preference” parameters depending on the type of...

We prove the existence of Pareto optimal allocations within sets of acceptable allocations when decision makers have probabilistic sophisticated variational preferences dened on random endowments in L1.

We consider in this paper two Markovian processes X and Y , solutions of a stochastic differential equation with jumps, that are comonotonic, i.e., that are such that for all t , almost surely, Xt is greater in one state of the world than in another if and only if the same is true for Yt . This...
