The Importance of Commitment in the New Keynesian Model

  • Jean-Paul Lam

    (Department of Economics, University of Waterloo)

In the New Keynesian model, even if the central bank does not have an over-ambitious output target, policy under discretion leads to an inefficiency known as the stabilisation bias. In this paper, using a New Keynesian model, we explore and quantify how various uncertainties such as an information lag, a cost channel and multi-period data revisions affect the size of the stabilisation bias. When an information lag is introduced in an otherwise standard New Keynesian model, we find that the size of the stabilisation bias is considerably reduced. The presence of a cost-channel in the model, on the other hand, increases the stabilisation bias significantly. Finally, multi-period revisions to output and inflation, reduces the inefficiency associated with discretionary policy.
