No monetarist, certainly not Friedman, welcomed this side-effect of monetary restraint. But then again, had Friedman been listened to earlier (and ha… - George Selgin

In one respect, however, I agree that monetarism was wrong, namely, to the extent that it failed to recognize the need to allow inflation to occur to the extent that it was solely due to falling output or productivity—a case I have argued, along with the symmetrical one for letting prices fall as productivity improves, in my IEA pamphlet Less Than Zero.

Your friend, rather perversely I think, refers to the "disastrous results" that followed the monetary tightening of Volcker and other more monetarist-minded central bankers without even hinting at the facts that that the tightening was aimed at bringing down inflation rates, and that it succeeded remarkably well in doing precisely that. In other words, the tightening did precisely what monetarism said it would do, and what monetarists' critics at the time, wedded to the view that monetary policy was ineffective, and that inflation was entirely caused by OPEC (or by unions, or by anything except monetary policy) insisted it could not do. And yet your friend imagines that the experience proved the monetarists wrong!

Although I realize that Austrian-school economists have themselves been highly critical of monetarism, many of its most fundamental claims are in fact fully consistent with their own understanding of monetary theory. Indeed, back in the 1970s the difference between Austrian and monetarists writings about money seemed trivial compared to the difference between them and the writings of other (broadly "Keynesian") economists. I recall very well how I myself got "deprogrammed" from mainstream thinking about money and inflation by reading Henry Hazlitt's wonderful book, The Inflation Problem, and How to Resolve It . Hazlitt was, of course, a thoroughgoing Misesian. Yet no one who reads his book can fail to note the many crucial similarities between his arguments and those of Milton Friedman concerning the same subject.
