Abstract

Woodford (2003) describes a popular class of neo-Wicksellian (NW) models in which monetary policy is characterized by an interest rate rule, and the money market and financial institutions are typically not even modeled. Critics contend that these models are incomplete and unsuitable for monetary policy evaluation. Our banks and bonds (BB) model starts with a standard NW model and then adds banks and a role for bonds in the liquidity management of households and banks. The BB model gives a more complete description of the economy, but the NW model has the virtue of simplicity. Our purpose here is to see if the NW model gives a reasonably accurate account of macroeconomic behavior in the more complete BB model. We do this by comparing the models' second moments, variance decompositions, and impulse response functions. We also study the role of monetary aggregates and velocity in predicting inflation in the two models.
