The paper contributes to understanding the economic dynamics at the zero lower bound and the exchange rate movements under different central bank intervention regimes. It provides a theoretical framework for modeling foreign exchange interventions at the ZLB within a dynamic general equilibrium...

We propose a new interest rate rule that implements the optimal equilibrium and eliminates all indeterminacy in a canonical New Keynesian model in which the zero lower bound on nominal interest rates (ZLB) is binding. The rule commits to zero nominal interest rates for a length of time that...

I compare nominal GDP level targeting to flexible inflation targeting in a small New Keynesian model subject to the zero lower bound on nominal policy rates. First, I study the performance of optimal discretionary policies. I find that, for a standard calibration, inflation targeting under...

This paper studies the effects of three financial shocks in the economy: a net-worth shock, an uncertainty or risk shock, and a credit-spread shock. We argue that only the latter can push the nominal interest rate against its zero lower bound. Further, a recessionary shock to the net worth or...

This paper employs stochastic simulations of the New Area-Wide Model - microfounded open-economy model developed at the ECB - to investigate the consequences of the zero lower bound on nominal interest rates for the evolution of risks to price stability in the euro area during the recent...
