Monetary Commitment and the Level of Public Debt

Stefano Gnocchi () and Luisa Lambertini

Staff Working Papers from Bank of Canada

Abstract: We analyze the interaction between committed monetary policy and discretionary fiscal policy in a model with public debt, endogenous government expenditures, distortive taxation and nominal rigidities. Fiscal decisions lack commitment but are Markov-perfect. Monetary commitment to an interest rate path leads to a unique level of debt. This level of debt is positive if the central bank adopts closed-loop strategies that raise the real interest rate when inflation is above target owing to fiscal deviations. More aggressive defence of the inflation target implies lower debt and higher welfare. Simple Taylor-type interest rate rules achieve welfare levels similar to those generated by sophisticated closed-loop strategies.
