In the framework of general equilibrium theory, this paper considers the existing relationship between the concepts of egalitarianism, efficiency and fairness, in a pure exchange economy with infinitely many goods. We consider the possibility of achieving an efficient egalitarian allocation in a...

In this work we ask is there a best model for uncertainty decisions? . ¿Which is the status of Simon bounded rationality: an alternative or complentary to traditional VNM theory?. ¿What has been the place of Prospect Theory?. We analize some paradoxes in order to explain some extentions and...

We analize the regulation established by the Banco de México in 2010 to commissions by interbank transactions at ATMs. Under a space model with a duopoly, we endogenize ATM deployment, account fees and ATM fees. We show that the commissions by interbank transactions remain unchanged. The...

We claim that economic agents driven by imitative behavior may impact the industrial specialization of national economies. We use a simple two-country model, where workers and firms decide to be skilled (or unskilled) and innovative (or non-innovative). We show that comparative advantages and...

Este trabajo, de carácter metodológico, esta motivado por dos preocupaciones: La primera se relaciona con un intento para discriminar entre la literatura comunicada por las revistas académicas de Economía. La segunda se refiere a la relación, poca o mucha, que hay entre los modelos de...

In this paper, from the excess utility function we obtain a binary relation in the social weights space and then, for an infinite dimensional economy, we prove the existence of equilibrium in our approach we don't suppose the existence of a demand function. Finally, we obtain a condition for the...

A stumbling block in the modeling of competitive markets with commodity and price spaces of infinite dimensions, arises from having positive cones with an empty interior. This issue precludes the use of tools of differential analysis, ranging from the definition of a derivative, to the use of...
