Chicago Fed President Charles Evans suggests a major break from the central bank's orthodoxy.

Chicago Federal Reserve president Charles Evans doesn't look the part of a heretic. But in the cozy, conservative club that is central banking, he certainly qualifies. While most of his colleagues at the Fed have recently taken an even more hawkish turn, Evans remains a champion of
additional monetary stimulus. And on Tuesday he took an even bigger step: He became the first sitting Fed member to
endorse nominal GDP (NGDP)
level targeting.
Sounds wonky? It is. But here's why Evans' suggestion is also extremely bold. The Fed famously has a dual mandate: It's supposed to promote the maximum level of employment consistent with its two-percent inflation target. In reality, this dual mandate often looks more like a
single inflation mandate. NGDP level targeting would do away with this problem by rolling the mandates together. And right now, that would mean a much more aggressive Federal Reserve.
The debate over NGDP level targeting and inflation targeting is part of a larger war that's been going on the past few years in the normally staid world of central banking. It's a three-sided debate over what the Fed should do now. There are those who think the Fed's dual mandate goes too far in promoting full employment, those who think it's just about right, and those who think it doesn't go far enough.
In the end, this is really a clash over inflation. After all, we're talking about central bankers here. The first group is worried that by effectively printing more money to goose the economy (better known to in policy circles as "quantitative easing"), the Fed has already created future inflation. The second group isn't worried about the money that's already been printed, but believes that running the presses any further will create future inflation. Finally, a third group is worried that if the Fed doesn't print more money, there won't be enough inflation to keep the economy healthy. Evans belongs to the last camp.
Actually, it's not quite true that Evans wants more inflation. He wants more income. To revert to econospeak, he wants the total size of the economy — that is, inflation plus growth, or nominal GDP — to get back to the long-term trend it was on before the financial crisis and recession. He would prefer if NGDP goes up due to real growth. But if it's a choice between stagnating NGDP and NGDP that's going up mostly because of inflation, Evans would choose the latter.
STOP WORRYING AND LEARN TO LOVE INFLATION
Why is steadily rising NGDP so important? It's about debt. Most contracts assume that NGDP will rise about five-percent a year. If NGDP (and incomes) doesn't go up that quickly, it becomes harder and harder for people to pay back their debts. That's what made the Great Recession so great. NGDP growth actually went negative for the first time in half a century. What started as a subprime problem became a widespread debt problem because people's incomes didn't increase like they expected.
But central banks don't usually speak the language of NGDP. They speak the language of inflation. It's not because inflation is a better signpost for policymakers than is NGDP. It's not. None other than Ben Bernanke said so in 2003, when he argued that both NGDP and inflation are the
best indicators for central bankers. It's more that people are more familiar with inflation. Besides, NGDP and inflation almost always give central bankers the same policy signal. Except for times like now.
Inflation is right around the Fed's two-percent target. But NGDP is
far, far below its long-term trend. What should the Fed do? So far, its answer has been: nothing. Evans disagrees. Up until Tuesday, he's framed his opposition in terms of inflation-targeting. His eponymous
rule of thumb has been that the Fed should commit to keeping interest rates at zero as long as unemployment is above seven-percent or inflation is below three-percent. It's a hybrid step between the Fed's current inflation-targeting regime and an NGDP level target. The idea is that the Fed should be more flexible about its inflation target when the economy is stuck in a deep hole, so we can dig ourselves out of it.
LESSONS FROM THE DEPRESSION
That brings us to the potential danger of the Fed's current policy. It might strangle the U.S. recovery. Strict-ish inflation targets — like the kind Bernanke & Co. are now pursuing (even if they say
they're not) — only work when the economy is working. As long as slumps aren't too big, everything is fine. But if the economy is depressed, a too-low inflation target acts like a
speed limit on recovery. Consider the Great Depression. Here's what happened to inflation after the economy bottomed out in FDR's first year in office.
