For the first time in nearly a decade, the Federal Reserve is considering raising its target interest rate, which would end a long period of near-zero rates. Like the cessation of large-scale asset purchases in October 2014, that action will be an important milestone in the unwinding of extraordinary monetary policies, adopted during my tenure as Fed chairman, to help the economy recover from a historic financial crisis. As such, it’s a good time to evaluate the results of those measures, and to consider where policy makers should go from here.
To begin, it’s essential to be clear on what monetary policy can and cannot achieve. Fed critics sometimes argue that you can’t “print your way to prosperity,” and I agree, at least on one level. The Fed has little or no control over long-term economic fundamentals—the skills of the workforce, the energy and vision of entrepreneurs, and the pace at which new technologies are developed and adapted for commercial use.
What the Fed can do is two things: First, by mitigating recessions, monetary policy can try to ensure that the economy makes full use of its resources, especially the workforce. High unemployment is a tragedy for the jobless, but it is also costly for taxpayers, investors and anyone interested in the health of the economy. Second, by keeping inflation low and stable, the Fed can help the market-based system function better and make it easier for people to plan for the future. Considering the economic risks posed by deflation, as well as the probability that interest rates will approach zero when inflation is very low, the Fed sets an inflation target of 2%, similar to that of most other central banks around the world.
How has monetary policy scored on these two criteria? Reasonable people can disagree on whether the economy is at full employment. The 5.1% headline unemployment rate would suggest that the labor market is close to normal. Other indicators—the relatively low labor-force participation rate, the apparent lack of wage pressures, for example—indicate that there is some distance left to go.
Not many will agree though..
