How does the need to preserve government debt sustainability affect the optimal monetary and fiscal policy response to a liquidity trap? To provide an answer, we employ a small stochastic New Keynesian model with a zero bound on nominal interest rates and characterize optimal time-consistent...

This paper studies monetary policy strategies under endogenous technology dynamics and low r*. Endogenous growth strengthens the gains from make-up strategies relative to inflation targeting, especially if policy space is reduced. This result is due to the long-run non-neutrality of money and...

This paper uses two established DSGE models (QUEST III and Smets-Wouters) to assess the impact of fiscal spending cuts on output and, in particular, also on inflation in the euro area under alternative settings for monetary policy. We compare four different settings of constrained monetary...

We study the incidence and severity of lower-bound episodes and the efficacy of three types of state-dependent policies—forward guidance about the future path of interest rates, large-scale asset purchases and spending-based fiscal stimulus—in ameliorating the adverse consequences stemming...

This paper analyzes monetary policy in a model with a potential unanchoring of inflation expectations. The degree of unanchoring is given by how sensitively the public’s long-run inflation expectations respond to inflation surprises. I find that optimal policy moves the interest rate...

This paper develops a simple, consistent methodology for generating empirically realistic forward guidance simulations using existing macroeconomic models by modifying expectations about policy announcements. The main advantage of our method lies in the exact preservation of all other shock...

We show that, when private sector expectations are determined in line with adaptive learning, optimal policy responds persistently to cost-push shocks. The optimal response is stronger and more persistent, the higher is the initial level of perceived inflation persistence by the private sector....

This paper considers the nominal and real determinacy of equilibria under an exogenously specified path of interest rates in an economy in which taxation is either lump-sum or distortionary. Under lump-sum taxation, we confirm the well-known finding that equilibria display nominal (in)...

This paper develops a tractable model of a monetary union with a sound fiscal governance structure and shows how in such environment the design of monetary policy above and at the lower bound constraint on short-term interest rates can be linked to well-known findings from the literature dealing...
