In this paper we first prove an equilibrium existence theorem for finite dimensional economies with unbounded below … give conditions for equivalence between absence of arbitrage and existence of equilibrium. Lastly, we introduce the concept …

-dimensional utility function (wealth and health status). We prove that the type of health risk influences the equilibrium of insurance …

In this paper we eliminate the free disposal assumption in a general equilibrium model in which the production sector … rules. Under standard assumptions in this framework, we state this existence of an equilibrium generalizing the classical …

asset terminal value. Second, from equilibrium pricing arguments one can put a monotonicity restriction on the Radon …

transfer rate mappings. We also define a new equilibrium condition on transfer rates and we prove the existence of core payoff … vectors satisfying this condition. The additional requirement of transfer rate equilibrium refines the core concept and allows … new setting and its associated equilibrium–core solution extend the usual cooperative game framework and core solution to …

In addition to normal equilibrium, two stationary disequilibria also exist (or regimes of long-term disequilibrium …

condition for the existence of an individually rational efficient allocation or of an equilibrium is that the relative interiors … more likely is an equilibrium to exist. The paper then turns to incomplete preferences represented by a family of concave … utility functions. Several definitions of efficiency and of equilibrium with inertia are considered. Sufficient conditions and …
