    Abstract

    Woodford (1999 and 2003) has raised the theoretical possibility that in a standard, forward looking sticky price model, an independent channel of inertia might arise as a result of policy behavior. We analyze this assertion empirically, and estimate a standard model, in which the monetary authority is assumed to commit to an optimal rule. We contribute to the existing literature by identifying the purely policy induced persistence present in the model. We also analyze the role of the structural parameters reflecting policy preferences and price flexibility in altering the policy induced, as well as the overall persistence properties of the model. We find that such a model is able to replicate most of the data's moments. In constrast to previous empirical literature, lagged terms in both modelled Phillips and IS curves are found to be either insignificant or very small. Commitment policy alone can explain a substantial part of output persistence. While the pricing mechanism at the heart of this model helps transfer output persistence into inflation persistence, commitment policy manages to undo this link by undershooting the inflation target following a positive 'cost push' shock so that inflation persistence is slightly reduced compared to the discretionary policy case.
