This paper presents an equilibrium model in a pure exchange economy when investors have three possible sources of … impact of investors heterogeneity on the properties of the equilibrium. In particular, we analyze the consumption shares, the …

Focusing mainly on equilibrium existence results, this paper emphasizes the role of fixed point theorems in the … development of general equilibrium theory, as well for its standard definition as for some of its extensions. …

coalition structure, we show that the stability index relative to the equilibrium, to the beta core and to the exact core is a …

Unlike partial equilibrium analysis which study the equilibrium of a particular market under the clause "ceteris … paribus" that revenues and prices on the other markets stay approximately unaffected, the ambition of a general equilibrium … model is to analyze the simultaneous equilibrium in all markets of a competitive economy. Definition of the abstract model …

finish by studying the existence and the unicity of the equilibrium in the sense of Lucas or Romer. …

general theorem on the existence of equilibrium without requiring that the commodity space or its dual be a vector lattice …

Compendious and thorough solutions to the existence of a linear price equilibrium problem, the second welfare theorem …. The motivation comes from economic applications showing the need to bring within the scope of equilibrium theory vector …

This paper explores risk-sharing and equilibrium in a general equilibrium set-up wherein agents are non … probability. Hence, optimal allocations are comonotone. This enables us to study the equilibrium set. When agents have different …

equilibrium existence theorems, especially in an infinite dimensional setting. For well-behaved exchange economies that we call … decentralizing Edgeworth equilibrium allocations as non-trivial equilibria. As we assume neither transitivity nor monotonicity on the … preferences of consumers, most of the existing equilibrium existence results are a consequence of our results. A natural …
