In addition, allowing for the possibility of a constantly changing fiscal stance adds to uncertainty and raises the risk that short-run politics, rather than effective use of public resources, will drive policy. So, the ideal fiscal approach was to set policy to support long-run priorities, minimizing short-run discretionary changes that can reduce economic efficiency.

Unless something changes, there is a good chance that when the next recession hits, monetary policymakers will once again find themselves stuck for an extended period at the lower bound for policy rates.
