Bienestar social, óptimos de Pareto y equilibrios walrasianos

In this work we analyze the relation between social welfare, and Pareto optimal allocations. As it is well know, each Pareto optimal allocation has associate a specific vector of social weights (one to each agent of the economy). This vector has associate a specific social utility function (the Negishi function) and then, each Pareto optimal allocation has associate a level of welfare. The concern of this work is to analyze the possibility that the economy reach, in a decentralized way, the maximum possible level of social welfare, considering as given the aggregate amount of its initial resources.
