Various policies that are being put on the table, including forms of fiscal and monetary stimulus, try to accelerate this repair process. They would all be likely to underperform, partly because the public, rightly or wrongly, doesn’t see them as ways to rebuild confidence. We have become skeptical of our own macroeconomic authorities and abilities, and that, in turn, makes successful policy harder to pull off.
For instance, there is a good case to be made for monetary expansion, given the current low rate of inflation and high rate of unemployment. But if fear of inflation puts off the American public, such a policy will again underperform, relative to what we have learned in textbooks. There won’t be a credible commitment to see the monetary stimulus through, as people panic that resulting inflation will be used to redistribute wealth. (Although Sweden and Switzerland have had effective monetary policies recently, both of those countries have especially high rates of trust in government.)
First, lack of trust stems in part from lack of effective government. Timely and sufficient stimulus would (or would have) demonstrably improved the economy and so boosted trust that government can act effectively.
