Abstract: Many argue that, because the economic outlook is inherently uncertain, central banks should apply a risk management approach to monetary policy, by promising a gradual liftoff of the policy interest rate from its lower bound. Using a small New Keynesian model with the central bank operating under optimal discretion, I compare the effects of uncertainty on economic performance, respectively under strict price level targeting and nominal gross domestic product (GDP) level targeting. As the results clarify, even though uncertainty hampers the effectiveness of monetary policy, the extent to which a central bank should delay liftoff depends crucially on its policy framework.
Keywords: nominal level targets; optimal policy; inertial Taylor rule
