In this paper, we consider a pure exchange economy with a finite number of agents who behave strategically on endowments. A notion of strategic equilibrium with partial disposability is defined and it is shown the existence of mixed strategies equilibria. Purification results on the strategic...

En este artículo se obtienen dos caracterizaciones de las asignaciones de equilibrio walrasiano en economías de intercambio con un número finito de consumidores. Ambas caracterizaciones se establecen en términos del poder de veto de la "gran coalición", formada por todos los agentes de la...

We consider infinite horizon economies with incomplete financial markets. Securities are in positive net supply and may be infinite-lived. We establish existence of equilibria by requiring borrowing constrains instead of portfolio restrictions..

In sequential economies with finite or infinite-lived real assets in positive net supply, we introduce constraints on the amount of borrowing in terms of the market value of physical endowments. We show that, when utility functions are either unbounded and separable in states of nature or...

We characterize the core and the competitive allocations of a continuum economy as strong Nash equilibria of an associated game with only two players.

We consider a differential information economy with infinitely many commodities and analyze the veto power of the grand coalition with respect the ability of blocking non-Walrasian expectations equilibrium allocations. We provide two different Walrasian expectations equilibrium equivalence...
