The Federal Reserve Board, Jobs and the Rewriting of Economic History By Dean Baker

As most people know, economists are good at rewriting history. We have seen this in the last few years as the collapse of the housing bubble and the ensuing downturn has been turned into one of those unavoidable tragedies that could not have been prevented. After all, no one could have imagined that house prices wouldn’t keep going up forever or that anything bad might happen if prices actually fell.

In reality it was possible, and in fact easy, for those who pay attention to data to know that house prices would fall [1] and that the consequences [2] for the economy would be very bad [3]. But most discussions of the crisis treat it as a natural disaster like Hurricane Katrina, and absolve the economists in policy positions from any responsibility.

Unfortunately this sort of reinvention of history is more than norm than the exception. We are witnessing another example in the debate over the timing of Federal Reserve Board interest rate hikes.

In this debate, many economists are arguing that the Fed has to move aggressively to raise interest rates in order to head off inflation. Some believe that the unemployment rate will soon be too low, if it is not already, and that we will start to see inflation spiral upwards if the Fed doesn’t act quickly to slow the pace of job creation.

While there is no evidence for these sorts of claims — inflation is currently below the Fed’s target and it has been falling, not rising — it is important to ask about the basis for these inflation warnings from economists. In this respect, the history of the 1990s is very important.

In the early and mid-1990s, virtually all mainstream economists argued that the inflation rate would begin to spiral upwards if the unemployment rate fell much below 6.0 percent. There were some differences on the exact measure of this danger point. Most conservative economists tended to put the danger point above 6.0 percent, perhaps as high 6.4 percent [4]. More liberal economists tended to view this floor unemployment rate as being somewhat below 6.0 percent, perhaps as low as 5.6 percent.

But there was very little disagreement about the basic point. We would have serious problems with inflation if the unemployment rate fell below this tipping point and the Federal Reserve Board should be prepared to raise interest rates to keep the unemployment from going too low. Even liberal economists like Paul Krugman and Janet Yellen, who was then a member of the Fed’s Board of Governors, argued for this position.

Remarkably, we had the opportunity to test this theory. Alan Greenspan, who was Fed chair in the 1990s, was not a mainstream economist and therefore did not accept that 6.0 percent, or anything like it, imposed a floor to the unemployment rate. He pushed and got a policy whereby the Fed allowed the unemployment rate to fall below 6.0 percent and to keep falling until there was clear evidence of inflation.
