Implications for Determinacy with Average Inflation Targeting

Abstract

We use a standard New Keynesian model to explore implications of backward- and forward-looking windows for monetary policy with average inflation targeting and investigate the conditions for determinacy. A unique equilibrium rules out sunspot shocks that can lead to self-fulfilling shocks for inflation expectations. We find limitations for the length of the forward window and demonstrate how this depends on other parameters in the model, including parameters governing monetary policy and expectations formation.
