I found yet another gold nugget in David Eagle’s research:

“In 2005 at the WEAI conference in San Francisco, Milton Friedman participated in panel where he strongly endorsed IT. After the panel presentations, an economist from the audience asked Friedman how he thought the Federal Reserve should respond to a broad-based 10% drop in real GDP. After spending some time trying think about what could possibility cause such a drop, Friedman responded by saying that the Federal Reserve should respond with a 10% drop in the money supply. However, immediately thereafter, Friedman inserted, “If you ask a foolish question, you get a foolish answer.””

Eagle continues:
“We disagree with Friedman concerning the foolishness of considering unexpected deviations in real GDP because that is when NIT (NGDP targeting) diverges from PLT (Price Level Targeting). Only by considering such unexpected real deviations can we see the differences in central bank responses under IT (Inflation targeting) or PLT from NIT (which we consider to be the equivalent of Friedman’s k percent rule). According to the new equation of exchange, N=PY, if Y unexpectedly increased while N (Nominal spending) remained as expected, the price level would unexpectedly fall. Under NIT, the central bank would be content to do nothing since N is on target. However, under PLT, the central bank would try to interject funds into the monetary system to try to raise N to match the increase in Y in order to return P to its targeted level. Similarly, if Y unexpectedly decreased while N remained as expected, the price level would unexpectedly increase. Under NIT, the central bank would be content to do nothing since N is on target. However, under PLT, the central bank would try to withdraw funds to try to cause N to fall to match the decline in Y in order that the price level not change.”

Hence, shortly before his dead Friedman indirectly said that he was not in favour of NGDP targeting. In my view that is not overly surprising. At that time official inflation targeting had been a success around the world for more than a decade and Friedman undoubtedly saw it as an vindication of his view that central banks should follow rules. So as always Friedman was the pragmatic revolutionary he simply support the successfully (at that time) version of a monetary rule, but I think that was on purely pragmatic reasons. Furthermore, one have to remember that at that time the primary monetary mistakes in recent history was too loose monetary policy rather than too tight monetary policy so from a pragmatic perspective it made “sense” to support inflation targeting.

As I have earlier argued Milton Friedman also acknowledged that velocity was no longer stable and that probably moved him from the left hand side to the right hand side of equation of exchange. By the way that shows that John Taylor’s use of Friedman to criticizing NGDP targeting by stating that Friedman argued that rules should be instrument rules really does not live up to what Friedman came believe in the final years of his life. Yes, Friedman endorsed inflation targeting, but NOT the Taylor rule (See David Glasner’s excellent critique of John Taylor views here). Furthermore, acknowledging that he did not think that velocity was stable (anymore) really makes it hard to use Friedman as an argument against NGDP targeting. BUT, BUT Friedman nonetheless to the end of his life preferred inflation targeting more than anything else.

Would that have change if he had live to see the Great Recession? I really don’t know and does it really matter? I still consider myself a Friedmanite and to me the best pupil of Friedman around is Scott Sumner!
