How QE Works: Evidence on the Refinancing Channel
How Quantitative Easing Works: Evidence on the Refinancing Channel⇤ § Marco Di Maggio† Amir Kermani‡ Christopher J. Palmer August 2019 Abstract We document the transmission of large-scale asset purchases by the Federal Reserve to the real economy using rich borrower-linked mortgage-market data and an identifica- tion strategy based on mortgage market segmentation. We find that central bank QE1 MBS purchases substantially increased refinancing activity, reduced interest payments for refinancing households, led to a boom in equity extraction, and increased aggre- gate consumption. Relative to QE-ineligible jumbo mortgages, QE-eligible conforming mortgage interest rates fell by an additional 40 bp and refinancing volumes increased by an additional 56% during QE1. We estimate that households refinancing during QE1 increased their durable consumption by 12%. Our results highlight that the transmis- sion of unconventional monetary policy to the real economy depends crucially on the composition of assets purchased and the degree of segmentation in the market. ⇤Apreviousversionofthispaperwascirculatedunderthetitle,“UnconventionalMonetaryPolicyand the Allocation of Credit.” For helpful comments, we thank our discussants, Florian Heider, Anil Kashyap, Deborah Lucas, Alexi Savov, Philipp Schnabl, and Felipe Severino; Adam Ashcraft, Andreas Fuster, Nicola Gennaioli, Robin Greenwood, Sam Hanson, Arvind Krishnamurthy, Stephan Luck, Michael Johannes, David Romer, David Scharfstein, Andrei Shleifer, Jeremy Stein, Johannes Stroebel, Stijn Van Nieuwerburgh, An- nette Vissing-Jørgensen, Nancy Wallace, and Paul Willen; seminar, conference, and workshop participants at Berkeley, Chicago Fed, Columbia, NBER Monetary, NBER Corporate Finance, Econometric Society, EEA, Fed Board, HEC Paris, MIT, Northwestern, NYU, NY Fed/NYU Stern Conference on Financial Intermedi- ation, Paul Woolley Conference at LSE, Penn State, San Francisco Fed, Stanford, St.
