No. I demonstrate that econometric estimations of nominal interest rate rules may tell little, if anything, about an economy's determinacy properties. In particular, correct inference about the interest-rate response to inflation provides no information about determinacy. Instead, it could...

We introduce skill decay during unemployment into Blanchard and Gali's (2008) New-Keynesian model with hiring frictions and real-wage rigidity. Plausible values of quarterly skill decay and realwage rigidity turn the long-run marginal cost-unemployment relationship positive in a "European"...

Does the Taylor rule prescribe negative interest rates for 2009-2011? This question is important because negative prescribed interest rates provide a justification for quantitative easing once actual policy rates hit the zero lower bound. We answer the question by analyzing Fed policy following...

In a simple New Keynesian model, we derive a closed form solution for the inflation-gap persistence parameter as a function of the policy weights in the central bank's Taylor rule. By estimating the time-varying weights that the FED attaches to inflation and the output gap, we show that the...

We develop a simple experimental setting to evaluate the role of the Taylor principle, which holds that the nominal interest rate has to respond more than one-for-one to fluctuations in the inflation rate. In our setting, the average inflation rate fluctuates around the inflation target if the...

Cyclical fluctuations in nominal variables|aggregate price levels and nominal interest rates are documented to be substantially more synchronized across countries than cyclical fluctuations in real output. A transparent mechanism that can account for this striking feature of the nominal...

What caused the U.S. economy's shift from the Great Inflation era to the Great Moderation era? A large literature shows that the shift was achieved by the change in monetary policy from a passive to an active response to inflation. However, Coibion and Gorodnichenko (2011) attribute the shift to...
