The Zero Lower Bound was irrelevant

Blog post for AIER by Brian C. Albrecht ’14 (Economics of Public Policy)

Brian Albrecht is a PhD candidate at the University of Minnesota and a graduate of the Barcelona GSE Master’s Program in Economics of Public Policy, as well as a past editor of the Barcelona GSE Voice. He is also a contributor to the Sound Money Project, a blog from the American Institute for Economic Research (AIER).

In a recent post, Brian talks about a recent paper by Barcelona GSE professors Davide Debortoli, Jordi Galí, and Luca Gambetti, “On the Empirical (Ir)Relevance of the Zero Lower Bound Constraint.” He writes:

Many economics writers, including Ben BernankeNeil Irwin, and Justin Wolfers, worry that the Fed will not be able to combat the next recession. Current interest rates, the sad story goes, are already close to zero. Since a downturn will push the economy to the zero lower bound (ZLB), the Fed will not be able to lower rates further, thereby prolonging the recession.

Of course, for such a story to make sense, the ZLB must be a fundamental constraint that inhibits monetary policy. In a new NBER working paper, Davide Debortoli, Jordi Galí, and Luca Gambetti consider whether the ZLB was actually the problem during the last recession. They say the ZLB was irrelevant. The authors come to this conclusion by studying two types of evidence: measures of macro volatility, and the response of macro variables to aggregate shocks through a vector autoregression.
