Our current inflation stemmed from a fiscal shock. The Fed is slow to react. Why? Will the Fed's slow reaction spur more inflation? I write a simple model that encompasses the Fed's mild projections and its slow reaction, and traditional views that inflation will surge without swift rate rises....

The fiscal theory states that inflation adjusts so that the real value of government debt equals the present value of real primary surpluses. Monetary policy remains important. The central bank can set an interest rate target, which determines the path of expected inflation, while news about the...

The narrative approach to macroeconomic identification uses qualitative sources, such as newspapers or government records, to provide information that can help establish causal relationships. This paper discusses the requirements for rigorous narrative analysis using fresh research on the impact...

Why do some attempts at disinflation lead to substantial reductions in inflation while others do not? We investigate this question in the context of the Federal Reserve's attempts at disinflation since World War II. Our central finding is that a fundamental determinant of success in reducing...

In response to the Global Financial Crisis, central banks engaged in large-scale asset purchases funded by the issuance of reserves. These "unconventional" policies continued during the pandemic, so that by 2022 central banks' balance sheets had grown up to ten-fold. As a result of rapidly...

We show that if the central bank operates without commitment and faces constraints on its balance sheet, helicopter drops can be a useful stabilization tool during a liquidity trap. With commitment, even with balance sheet constraints, helicopter drops are irrelevant

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...

The world economy has experienced the largest financial crisis in generations, a global pandemic, and a resurgence in inflation during the first quarter of the 21st century, yielding important insights for central banking. Price stability has important benefits and is the responsibility of a...

We examine the transmission of monetary policy shocks to the long-duration liabilities of households and firms using high-frequency variation in 10-year swap rates around FOMC announcements. We find that four weeks after the announcement mortgage rates move one-for-one with 10-year swap rates,...

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...
