Recent empirical evidence by Fair (2002, 2005) and Giordani (2003) shows that a positive inflation shock with the nominal interest rate held constant has contractionary effects. These results cannot be reconciled with the standard "New Synthe- sis" literature. This paper reconsiders the effects of inflation shocks in a simple New Keynesian framework extended to include wealth effects. It is demonstrated that, following an inflation shock, the decline of output coupled with passive interest rate rules is not puzzling
