Description: "In previous work (Eggertsson and Woodford, 2003), we characterized the optimal conduct of monetary policy when a real disturbance causes the natural rate of interest to be temporarily negative, so that the zero lower bound on nominal interest rates binds, and showed that commitment to a history-dependent policy rule can greatly increase welfare relative to the outcome under a purely forward-looking inflation target.  Here we consider in addition optimal tax policy in response to such a disturbance, to determine the extent to which fiscal policy can help to mitigate the distortions resulting from the zero bound, and to consider whether a history-dependent monetary policy commitment continues to be important when fiscal policy is appropriately adjusted.  We find that even in a model where complete tax smoothing would be optimal as long as the zero bound never binds, it is optimal to temporarily adjust tax rates in response to a binding zero bound; but when taxes have only a supply-side effect, the optimal policy requires that the tax rate be raised during the "trap", while committing to lower tax rates below their long-run level later.  An optimal policy commitment is still history-dependent, in general, but the gains from departing from a strict inflation target are modest in the case that fiscal policy responds to the real disturbance in an appropriate way"--National Bureau of Economic Research web site.
