US monetary policy was constrained from 2008 to 2015 by the zero lower bound, during which the Federal Reserve would likely have lowered the federal funds rate further if it were able to. This paper uses industry-level data to examine how growth was affected. Despite the zero bound constraint, industries historically more sensitive to interest rates, such as construction, performed relatively well in comparison to industries not typically affected by monetary policy. Further evidence suggests that unconventional policy lowered the effective stance of policy below zero.

We estimate a shadow rate consistent with the paths of time series capturing real activity. This allows us to quantify the real effects of unconventional monetary policy in terms of equivalent short-term interest rate movements. We find that large-scale asset purchases and forward guidance had significant real effects equivalent of up to a four percent reduction in the federal funds rate.
