The existence of an exact Walrasian equilibrium in non convex economies is still a largely unexplored issue. In this paper an existence result for exact equilibrium in non convex economies is provided by following the "almost-near" approach introduced by Postlewaite and Schmeidler for convex...

The geometric analysis of Cournot-Nash (CN) equilibrium has been developed mainly by using reaction curves (see, e.g. Tirole (1988), Cabral (2000)). Since they are defined in the quantity space, the use of such graphical approach yields a discontinuity with respect to the perfectly competitive,...

The problem of choice of technique in single production linear models has been extensively analysed under the assumption that the set of processes available in the economy is exogenously given and globally known. However, since Atkinson and Stiglitz's 1969 article economists have considered...

The existence of an exact Walrasian equilibrium in nonconvex economies is still a largely unexplored issue. This paper shows that such an equilibrium exists in nonconvex economies by following the nearby economyapproach introduced by Postlewaite and Schmeidler (Approximate Walrasian Equilibrium...

This note provides a new proof of the existence of a walrasian equilibrium in pure exchange economies under quite standard and general assumptions. The proof still employs a fixed point argument, however, it is shorter and simpler than those currently available for the case considered
