In this paper I consider the following problem: there is a collection of, exogenously given, socially feasible sets, and for each one of them, each one of a group of individuals chooses from an individually feasible set. The fact that the product of the individually feasible sets is larger than...

The theory of general equilibrium was criticized for its apparent lack of testable implications, as seemingly implied by the results of Sonnenschein, Mantel and Debreu in the Seventies. This view was challenged by the results of Brown and Matzkin (1996), which showed the existence of testable...

This paper studies the falsifiability of the hypothesis of Nash behavior, for the case of a finite number of players who choose from continuous domains, subject to constraints. The results obtained here are negative. Assuming the observation of finite data sets, and using weak, but nontrivial,...

The following is proven here: let W : X × C −→ R, where X is convex, be a continuous and bounded function such that for each y ∈ C, the function W (·, y) : X −→ R is concave (resp. strongly concave; resp. Lipschitzian with constant M; resp. monotone; resp. strictly monotone) and let Y...

Desde la propuesta de Schumpeter (1911)(1)de que los servicios prestados por el sistema financiero son importantes para la promoción de la innovación tecnológica y el crecimiento económico(2). ha existido un relativo consenso entre los economistas en el sentido de que el desarrollo del...
