These shock series avoid the omitted variable, time-varying parameter, and orthogonalization problem of monthly VARs, and do not impose the expectations hypothesis. We find surprisingly large and persistent responses of bond yields to these shocks. 10 year rates rise as much as 8/10 of a percent to a one percent target shock. The usual view that monetary policy only temporarily raises long term rates and influences inflation would lead one to predict a negative long rate response. ER -
