Abstract
This paper compares different implementations of monetary policy in a newKeynesian setting. We can show that a shift from Ramsey optimal policy under shortterm commitment (based on a negative feedback mechanism) to a Taylor rule (based on a positive feedback mechanism) corresponds to a Hopf bifurcation with opposite policy advice and a change of the dynamic properties. This bifurcation occurs because of the ad hoc assumption that interest rate is a forwardlooking variable when policy targets (inflation and output gap) are forwardlooking variables in the newKeynesian theory.
