In this work, we attempt to characterize the main theoretical difficulties to prove the existence of competitive equilibrium in infinite dimensional models. We shall show cases in which it is not possible to prove the existence of equilibrium and some others in which, however the existence of...

The analysis of the evolution of wage polarization in Uruguay during the last twelve years shows that the distribution of wages has become progressively more unequal and, most of all, more polarized. Increased premia to skill and experience, together with increased wage differentials by economic...

The aim of this paper is to relate the General Equilibrium Theory and modern Finance Theory. We work with an infinite dimensional economy with a market for goods an actives, and where the number of agents is finite. Each agent has an intertemporal utility function with uncertainty on the states...

The transnational corporations have been the most remarkable economic phenomena of the post-war period. They are the modern incarnation of the great corporations of the end of the XIX century. But, beyond its common characteristics, it is important to underline the specific attributes of this...

Social Security systems in Latin America prior to the reforms exhibited some problems that have been reported also in other parts of the world, including OECD countries. This is the case for instance of the increasing pressure that the pension system put on fiscal accounts. Other problems that...

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...
