The cost of nominal inertia in NNS models2004

"We calculate the welfare cost of nominal inertia in a New Neoclassical Synthesis model with wage and price stickiness, capital formation, and empirically estimated rules for government spending and the cental bank's interest rate policy. We calibrate our model to U.S. data, and we show that it captures many aspects of the U.S. business cycle. Moreover, our model is capable of generating the kind of volatility that has been observed in the efficiency gaps emphasized by Erceg, Henderson and Levin (2000) and Gali, Gertler and Lopez-Salido (2002). We also highlight some of the empirical shortcomings of the model; in particular, demand side shocks appear to be either missing or improperly modeled. We calculate the cost of nominal inertia under two specifications of monetary policy. The...
