At Barry Ritholtz's blog, a graphic that purports to show the "top five hundred influencers" in the U.S. economy. In fact, it shows only the impact of various gum-flappers, columnists, and bloggers. The real "top five hundred influencers" are scarcely known because they run businesses, or make hugely consequential decisions in regulatory agencies and central banks that create winners and losers among those businesses.
Oh. And I wonder if Ritholtz is correct in his assessment that Paul Krugman is more influential than Zero Hedge. I do not know a single person in business who gives an overripe fig what Paul Krugman thinks about anything, so his "influence" must be confined to the central bankers and regulators (who surely do not read Zero Hedge...).
