Stabilisation bias in monetary policy under endogenous price stickiness
Martin Ellison
Abstract: This paper investigates the consequences of introducing
endogenous price stickiness into a standard monetary policy model. We find
that the modification reduces the optimal degree of inflation stabilization
to which the central bank should commit. The reason is that less inflation
stabilization encourages firms to review their prices more frequently. The
economy becomes more flexible and the Phillips-curve tradeoff is improved,
making it easier for the central bank to control inflation. This reduces,
and may even reverse, the stabilization bias that is present in models with
exogenous price stickiness and that recommends that the central bank
generally commit to tighter stabilization of inflation than it would in a
discretionary policy regime.
