This article assesses the importance of the zero lower bound on nominal interest rates for the conduct of monetary policy. The article employs a small, forward-looking model developed by Fuhrer and Moore. The model is simulated under several policy rules that involve either high or low inflation...

This paper uses Whiteman's(1986) frequency-domain optimization methodology to parameterize the precommitment period in a standard rational expectations policy design model. This allows researchers to adopt an empirical approach to the time consistency issue. That is, the operative commitment...

Estimates are provided for the social cost of inflation in the U.S. economy. The estimated cost, expressed as a fraction of income, is proportional to the square root of the nominal interest rate. This approximation assigns much higher costs to low rates of inflation than does the familiar...

We study discretionary equilibrium in the Calvo pricing model for a monetary authority that chooses the money supply. The steady-state inflation rate is above 8 percent for a baseline calibration, but it varies substantially with alternative structural parameter values. If the initial condition...

We derive and estimate a New Keynesian Phillips curve (NKPC) in a model where consumers are assumed to have deep habits. Habits are deep in the sense that they apply to individual consumption goods instead of aggregate consumption. This alters the NKPC in a fundamental manner as it introduces...
