This paper studies the implications of household heterogeneity for the effectiveness of quantitative easing (QE). We consider a heterogeneous agent New Keynesian (HANK) model with uninsurable household income risk. Financial intermediaries are subject to an endogenous leverage constraint that...

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 separately identify and estimate the effects of the Federal Reserve's federal funds rate, forward guidance, and large-scale asset purchase (LSAP) policies on the U.S. economy. I extend the high-frequency identification strategy of Bauer and Swanson (2023b) for monetary policy VARs by allowing...

We conduct a systematic analysis of the costs and benefits of large-scale securities purchases, using the Federal Reserve's QE4 program as a concrete example. This program was initiated at the onset of the pandemic in March 2020 and continued for two years, leading to a doubling of the Fed's...

Before the era of large central bank balance sheets, banks relied on incoming payments to fund outgoing payments in order to conserve scarce liquidity. Even in the era of large central bank balance sheets, rather than funding payments with abundant reserve balances, we show that outgoing...

We propose a tractable and coherent framework that captures both conventional and unconventional monetary policies with the shadow fed funds rate. Empirically, we document the shadow rate's resemblance to an overall financial conditions index, various private interest rates, the Fed's balance...

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...

What are the effects of monetary policy on exchange rates? And have unconventional monetary policies changed the way monetary policy is transmitted to international financial markets? According to conventional wisdom, expansionary monetary policy shocks in a country lead to that country's...

In a collaborative project with ten central banks, we have investigated the causes of the post-pandemic global inflation, building on our earlier work for the United States. Globally, as in the United States, pandemic-era inflation was due primarily to supply disruptions and sharp increases in...
