When infinite lived agents trade long-lived assets secured by durable goods, equilibrium exists without any uniform impatience requirements or additional debt constraints. Asset pricing bubbles are absent when the new endowments of durable goods are uniformly bounded away from zero. Otherwise,...

Without introducing either debt constraints or transversality conditions to avoid the possibility of Ponzi schemes, we show the existence of equilibrium in an infinite horizon incomplete markets economy with a collateral structure. Copyright The Econometric Society 2002.

We address a dynamic general equilibrium model where securities are backed by collateralized loans, and borrowers face endogenous liquidity contractions and financial participation constraints. Although the only payment enforcement is the seizure of collateral guarantees, restrictions on credit...

This paper presents a dynamic general equilibrium model with default and collateral requirements. In contrast with previous literature, our model allows for liquidity contractions and general prepayment specifications. We show that liquidity substantially affects credit and prepayment risks, and...

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..

We develop a general equilibrium model of wealth transfers in the presence of uncertain lifetimes and default. Without introducing exogenous debt constraints, agents are allowed to make collateral-backed promises at any state of their life span.

Introducing assets backed by physical collateral, we extend the Cornet and De Boisdeffre (2002) model of asymmetric information to allow for default. We show that, independently of the financial-informational structure, equilibrium exists.
