I have met both Joe Stiglitz and Stanley Fischer. I trust and respect Fischer. Stiglitz not so much.
Stiglitz gave the economics profession the theoretical framework called "asymmetric information", according to which sellers often have much better information about their products and therefore are in a position to take advantage of less-well-informed buyers. His solution? Gubmnt intervention.
The George Stigler (not Joe Stiglitz!) solution? Reputation matters, and people will learn who to trust and who not to trust. Joe Stiglitz criticizes that approach, arguing markets would do better with proper gubmnt intervention.
Stiglitz seems to believe that if only he and his ilk could make all the economic policy decisions, there would be no problems. And yet he has been so wrong so often, it's hard to understand why people pay attention to him anymore.
This is the point made very well in "Continually Mistaken, Chronically Admired: ... a study in elite myopia," an article published last fall but that I just ran across (h/t Bill Evers).
The article documents how Stiglitz:
- praised Venezuelan socialism
- praised Ethiopian demogoguery
- opposed the Trans-Pacific trade pact
- completely missed the Asian financial crisis
- opposed raising the minimum wage and then favoured it with arguments that had nearly everyone else scratching their heads
- completely missed the problems of risky mortgages in praising and defending the pre-crisis work of Fannie Mae and Freddie Mac
Stiglitz is the quintessential elitist interventionist who loves to talk about market failures (with little acknowledgement that most of the failures he deals with are dealt with adequately in the market), but he rarely if ever acknowledges that gubmnt policies are made and implemented by fallible people.
Stiglitz never met an argument for gubmnt intervention that he didn't like. He really needs to study more economic history and more about gubmnt failure, along with all the reasons gubmnt interventions are often much worse than the alleged market failures they have been instituted to "fix".
Why do I mention Fischer in my opening sentence? Because Stiglitz incorrectly accused him of impropriety. It looks like pot-kettle-black to me, given Stiglitz's cozying up with so many socialist and other dictators.
As Harold Demsetz once wrote, it is important in economics to compare feasible alternatives. Stiglitz doesn't do that; instead he frequently rails against imperfect markets, arguing they can be improved with "perfect" regulators and policies. It ain't gonna happen that way, Joe.
