The aim of this paper is to characterise the set of non regular economies, when there is a finite number of consumers with either finite or infinitely many goods. We prove that the structure of the equilibrium set is the same in both cases and that there exist bifurcations in some of these models.

The aim of this paper if to characterize the set of singular economies, when there are a finite set of consumers with infinitely many goods in the sense that goods differ in the time which they are consumed or in the state of the world in which they become available. There exist l available...

We consider a pure exchange economy, where agent's consumption spaces are Banach spaces, goods are contingent in time of states of the world, the utility function of each agent is not necessarily a separable function, but increasing, quasiconcave, and twice Frechet differentiable over the...

In this paper we show that in a pure exchange economy it is possible to improve the social welfare along an e±cient path. This path will be called the Negishi map. Moving the relative weights of the agent in a social welfare utility function, we obtain an e±cient path of allocations and social...

In this paper we analyze, from the Negishi approach the concepts of structurally stable and structurally unstable economies on Banach's spaces. With this purpose we formalize the intuitive concept of similar economies. We show that in certain cases similar (or neighboring) economies can show no...

The object of this paper is to show some examples of economies in which singular equilibria occur as a consequence of utility functions and where this equilibria play a crucial rolle to understand the behavior of the economy as a system. An economy will be called singular if little changes in...

En este documento se examina la evolución de las economías de América Latina en 1990–2011, con el fin de identificar avances, pendientes y retrocesos asociados a las reformas de mercado que se aplicaron, en línea con el Consenso de Washington, y a las políticas económicas que le...
