Recently Kajii and Ui (2009) [17] proposed to characterize interim efficient allocations in an exchange economy under asymmetric information when uncertainty is represented by multiple posteriors. When agents have Bewley's incomplete preferences, Kajii and Ui (2009) [17] proposed a necessary and...

We introduce differential information in the asset market model studied by Cheng (1991), Dana and Le Van (1996) and Le Van and Truong Xuan (2001). An equilibrium existence result is proven assuming that the economy's information structure satisfies the conditional independency property.

Páscoa and Seghir (2009) presented two examples to show that in the presence of utility penalties for default, collateral requirements do not always eliminate the occurrence of Ponzi schemes and equilibria may fail to exist. This paper aims at providing a counterexample to their claim. We show...

The objective of the paper is to propose endogenous debt constraints that rule out Ponzi schemes and ensure the existence of equilibria in a model with limited commitment and (possible) default. We appropriately modify the definition of finitely effective debt constraints, introduced by Levine...

The paper proposes an alternative general equilibrium formulation of financial asset economies with transactions costs. Transaction costs emerge endogenously at equilibrium and reflect agents decisions of intermediating financial activities at the expense of providing labor services. An...
