I'm not convinced (along with Robert Murphy, the Wall Street Journal, and others) - if anything, the fact that Yellen would be a continuation of Helicopter Ben's policies should automatically raise suspicion. She is already on record as part of the "a little inflation now and then is a good thing" school, which would in and of itself be problematic... but is even worse with a Fed actively stoking the fires of hyperinflation and basing its policy decisions on perhaps the wrong metrics. In fact, as noted in this article, "I think it’s a fair reading of a typical Janet Yellen speech that she’s more concerned about high unemployment.” This is precisely the central bank mentality that led to stagflation of the 1970s.
Besides, anyone who Joseph Stiglitz likes already has two strikes against them.
