This paper studies a simple monetary model with a Ricardian fiscal policy in which equilibria are indeterminate if monetary policy consists solely of a rule for fixing the short-term interest rate. We introduce explicitly into the model the agents’ expectations of inflation which create the...

This paper studies the existence and uniqueness of equilibrium in a monetary model in which the fiscal policy is Ricardian. The innovation of the paper is to model agents’ expectations as endogenous probabilities which are determined in equilibrium. Since economies with a Ricardian fiscal...

An account is given of the principal concepts and results of general equilibrium with incomplete financial markets over a finite horizon, focusing on the generic existence, suboptimality and determinacy of equilibrium. Many results depend on the nature of the financial securities, whether they...

This paper uses the framework of an OLG economy with three-period lived agents in which a durable good serves as collateral for loans, to study the effect of an unanticipated income shock when the economy is in a steady state equilibrium. We focus on the consequence of default on loans when the...
