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,...

<Para ID="Par1">We develop revealed preference tests for models of multi-product oligopoly, building on the work in Carvajal et al. (Econometrica 81(6):2351–2379, <CitationRef CitationID="CR8">2013</CitationRef>). We analyze a Cournot model with multiple goods and show that it has testable restrictions when at least one good is produced by two or more...</citationref></para>

Decades back, a most prominent justice philosopher, John Rawls, put forth a clear definition of fairness in problems of social choice. Decision theory, which studies individual, and not social, choice has provided axiomatizations of decision rules in many settings, most prominently in settings...

In economies subject to uninsurable idiosyncratic risks, competitive equilibrium allocations are constrained inefficient: reallocations of assets support Pareto superior allocations. This is the case even if the asset market for the allocation of aggregate risks is complete.

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...
