And celebrity is no shield against Fed excommunication. Paul Krugman, in fact, has gotten rough treatment. "I've been blackballed from the Fed summer conference at Jackson Hole, which I used to be a regular at, ever since I criticized him," Krugman said of Greenspan in a 2007 interview with Pacifica Radio's Democracy Now! "Nobody really wants to cross him."
An invitation to the annual conference, or some other blessing from the Fed, is a signal to the economic profession that you're a certified member of the club. Even Krugman seems a bit burned by the slight. "And two years ago," he said in 2007, "the conference was devoted to a field, new economic geography, that I invented, and I wasn't invited."
This is from a fairly detailed Huffington Postarticle on the huge potential influence the Federal Reserve System can have (is having?) on the bounds of discussion about Fed policy.
Here's a paragraph about Milton Friedman:
Even the late Milton Friedman, whose monetary economic theories heavily influenced Greenspan, was concerned about the stifled nature of the debate. Friedman, in a 1993 letter to Auerbach that the author quotes in his book, argued that the Fed practice was harming objectivity: "I cannot disagree with you that having something like 500 economists is extremely unhealthy. As you say, it is not conducive to independent, objective research. You and I know there has been censorship of the material published. Equally important, the location of the economists in the Federal Reserve has had a significant influence on the kind of research they do, biasing that research toward noncontroversial technical papers on method as opposed to substantive papers on policy and results," Friedman wrote.
My former colleague from University of Rochester days, Robert King, is quoted as saying that the idea that the Fed influences thinking about Fed policy through its subsidization of hundreds of economists is "silly." But we economists are trained to think about incentives. Why wouldn't incentives apply here? There is one way the Fed could put some of these fears to rest: invite critics who would like to end the Fed to their next Jackson Hole meeting: George Selgin, Lawrence H. White, and Jeffrey Hummel.
