When a Nobel Prize Isn’t Enough

LAST October, I won the Nobel Prize in economics for my work on unemployment and the labor market. But I am unqualified to serve on the board of the Federal Reserve — at least according to the Republican senators who have blocked my nomination. How can this be?

The easy answer is to point to shortcomings in our confirmation process and to partisan polarization in Washington. The more troubling answer, though, points to a fundamental misunderstanding: a failure to recognize that analysis of unemployment is crucial to conducting monetary policy.

In April 2010, President Obama nominated me to be one of the seven governors of the Fed. He renominated me in September, and again in January, after Senate Republicans blocked a floor vote on my confirmation. When the Senate Banking Committee took up my nomination in July and again in November, three Republican senators voted for me each time. But the third time around, the Republicans on the committee voted in lockstep against my appointment, making it extremely unlikely that the opposition to a full Senate vote can be overcome. It is time for me to withdraw, as I plan to inform the White House.

The leading opponent to my appointment, Richard C. Shelby of Alabama, the ranking Republican on the committee, has questioned the relevance of my expertise. “Does Dr. Diamond have any experience in conducting monetary policy? No,” he said in March. “His academic work has been on pensions and labor market theory.”

But understanding the labor market — and the process by which workers and jobs come together and separate — is critical to devising an effective monetary policy. The financial crisis has led to continuing high unemployment. The Fed has to properly assess the nature of that unemployment to be able to lower it as much as possible while avoiding inflation. If much of the unemployment is related to the business cycle — caused by a lack of adequate demand — the Fed can act to reduce it without touching off inflation. If instead the unemployment is primarily structural — caused by mismatches between the skills that companies need and the skills that workers have — aggressive Fed action to reduce it could be misguided.

In my Nobel acceptance speech in December, I discussed in detail the patterns of hiring in the American economy, and concluded that structural unemployment and issues of mismatch were not important in the slow recovery we have been experiencing, and thus not a reason to stop an accommodative monetary policy — a policy of keeping short-term interest rates exceptionally low and buying Treasury securities to keep long-term rates down. Analysis of the labor market is in fact central to monetary policy.

Senator Shelby also questioned my qualifications, asking: “Does Dr. Diamond have any experience in crisis management? No.” In addition to setting monetary policy in light of a proper understanding of unemployment, the Fed is responsible for avoiding banking crises, not just trying to mop up afterward.

Among the issues being debated now is how much we should increase capital requirements for banks. Selecting the proper size of the increase requires a balance between reducing the risk of a future crisis and ensuring the effective functioning of financial firms in ordinary times. My experience analyzing the properties of capital markets and how economic risks are and should be shared is directly relevant for designing policies to reduce the risk of future banking crises.

Instead of going to the Fed, however, I will go about my congenial professional existence as a professor at M.I.T., where I have taught and researched since 1966, and I will take advantage of some of the many opportunities that come to a Nobel laureate. So don’t worry about me.

But we should all worry about how distorted the confirmation process has become, and how little understanding of monetary policy there is among some of those responsible for its Congressional oversight. We need to preserve the independence of the Fed from efforts to politicize monetary policy and to limit the Fed’s ability to regulate financial firms.

Concern about the (seemingly low) current risk of future inflation should not erase concern about the large costs of continuing high unemployment. Concern about the distant risk of a genuine inability to handle our national debt should not erase concern about the risk to the economy from too much short-run fiscal tightening.

To the public, the Washington debate is often about more versus less — in both spending and regulation. There is too little public awareness of the real consequences of some of these decisions. In reality, we need more spending on some programs and less spending on others, and we need more good regulations and fewer bad ones.

Analytical expertise is needed to accomplish this, to make government more effective and efficient. Skilled analytical thinking should not be drowned out by mistaken, ideologically driven views that more is always better or less is always better. I had hoped to bring some of my own expertise and experience to the Fed. Now I hope someone else can.
