Christina Romer on targeting nominal GDP

By pledging to do whatever it takes to return nominal G.D.P. to its pre-crisis trajectory, the Fed could improve confidence and expectations of future growth.

Such expectations could increase spending and growth today: Consumers who are more certain that they’ll have a job next year would be less hesitant to spend, and companies that believe sales will be rising would be more likely to invest.

Another possible effect is a temporary climb in inflation expectations. Ordinarily, this would be undesirable. But in the current situation, where nominal interest rates are constrained because they can’t go below zero, a small increase in expected inflation could be helpful. It would lower real borrowing costs, and encourage spending on big-ticket items like cars, homes and business equipment.
