We build a tractable New Keynesian model to jointly study four types of monetary and fiscal policy. We find quantitative easing (QE), lump-sum fiscal transfers, and government spending have the same effects on the aggregate economy when fiscal policy is fully tax financed. Compared with these...

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...

This paper studies the effectiveness of forward guidance when central banks have imperfect credibility. Exploiting unique survey-based measures of expected inflation, output growth, and interest rates, we estimate a small-scale New Keynesian model for the United States and other G7 countries...

In this paper we set up a New-Keynesian model with a heterogenous banking sector to analyze liquidity problems on the interbank market. The presence of an interbank market is essential to consider a situation where an increased liquidity supply by the central bank is only partially passed on to...

The past half-century has seen major shifts in inflation expectations, how inflation comoves with the business cycle, and how stocks comove with Treasury bonds. Against this backdrop, we review the economic channels and empirical evidence on how inflation is priced in financial markets. Not all...

In a standard open-economy New Keynesian model, the effective lower bound causes anomalies: output and terms of trade respond to a supply shock in the opposite direction compared to normal times. We introduce a tractable two-country model to accommodate for unconventional monetary policy. In our...

I analyze monetary policy with interest on reserves and a large balance sheet. I show that conventional theories do not determine inflation in this regime, so I base the analysis on the fiscal theory of the price level. I find that monetary policy can peg the nominal rate, and determine expected...

We examine how private sector agents might learn a new monetary strategy that is adopted while at the ELB. Little can be discovered until the economy improves enough that rates would be near liftoff under the old strategy. Recessionary shocks would thus delay learning while large inflationary...

Nonetheless, we find that the target criterion--a linear relation that should be maintained between the inflation rate and changes in the output gap--that characterizes optimal policy in the basic NK model continues to provide a good approximation to optimal policy, even in the presence of...

We develop a multisector, open economy, New Keynesian framework to evaluate how potentially binding capacity constraints, and shocks to them, shape inflation. We show that binding constraints for domestic and foreign producers shift domestic and import price Phillips Curves up, similar to...
