In this paper an empirical model for analyzing the behavior of nominal interest rates in a semi-open economy is developed. The model explicitly incorporates both the role of open economy factors (i.e., world interest rates, expected rate of devaluation) and domestic monetary conditions in...

Following the crisis of 2008, several central banks engaged in a new experiment by setting negative policy rates. Using aggregate and bank level data, we document that deposit rates stopped responding to policy rates once they went negative and that bank lending rates in some cases increased...

This paper investigates whether permanent monetary tightenings increase inflation in the short run. It estimates, using U.S. data, an empirical and a New-Keynesian model driven by transitory and permanent monetary and real shocks. Temporary increases in the nominal interest-rate lead, in...

I survey the literature on monetary policy at the zero lower bound (ZLB) and effective lower bound (ELB) to make three main points: First, the Federal Reserve's forward guidance and large-scale asset purchases are effective monetary policy tools at the Z/ELB. Second, during the 2008-15 U.S. ZLB...

We study the macroeconomic effects of internal devaluations undertaken by a periphery of countries belonging to a monetary union. We find that internal devaluations have large and positive output effects in the long run. Through an expectations channel, most of these effects carry over to the...

Cyclical fluctuations in nominal variables--aggregate price levels and nominal interest rates--are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal...

I investigate the effects of an increase in the nominal interest rate on inflation and output in the United States and Japan during the postwar period. I postulate a structural autoregressive model that allows for transitory and permanent nominal and real shocks. I find that nominal...

We study the optimal monetary policy problem in a New Keynesian economy with a zero lower bound (ZLB) on the nominal interest rate, when the steady state natural rate (r*) becomes permanently negative. We show that the optimal policy aims to approach gradually a new steady state with positive...
