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 falsiability of the hypothesis of Nash behavoir, 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 non-trivial,...

Las empresas de base tecnológica (EBT) adquieren un papel cada vez más relevante en el aprovechamiento deventanas de oportunidad para el desarrollo del sistema nacional e internacional de competitividad (Campos et al.2009). El problema de financiación de las EBT se ha delimitado al apoyo de...

This paper examines the optimal bundling strategies of a multiproduct monopoly in markets in which a seller cannot monitor and thereby restrict the purchases of buyers to a single bundle, while buyers have resale opportunities. In such markets, the standard mechanism through which bundling...

We present an extension of Aumann's Agreement Theorem to the case of multiple priors. If agents update all their priors, then, for the Agreement Theorem to hold, it is sufficient to assume that they have closed, connected and intersecting sets of priors. On the other hand, if agents select the...

We show that even under incomplete markets, the equilibrium manifold identifies aggregate demand and individual demands everywhere in their domains. Moreover, under partial observation of the equilibrium manifold, we we construct maximal domains of identification. For this, we assume conditions...

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...
