Anchoring expectations of inflation

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 policy typically exhibit indeterminacy of equilibrium when the monetary policy instrument is the short-term interest rate, we augment the instruments of monetary policy to the interest rates on a family of bonds of maturities 1,…,T and derive conditions under which this ensures uniqueness of equilibrium.
