Paul Krugman's assessment of Milton Friedman's work in this week's New York Review of Books is a true must-read, affirming once-again Krugman's status as the greatest living communicator of economic thought and history. Friedman's death was followed by a flood of underwhelming obituaries, impenetrably technical arguments, and conservative hagiographies. So Krugman's piece, which capably disentangles Friedman's careful economic work from his substantially less-cautious political advocacy is a welcome antidote:
Milton Friedman played three roles in the intellectual life of the twentieth century. There was Friedman the economist's economist, who wrote technical, more or less apolitical analyses of consumer behavior and inflation. There was Friedman the policy entrepreneur, who spent decades campaigning on behalf of the policy known as monetarism—finally seeing the Federal Reserve and the Bank of England adopt his doctrine at the end of the 1970s, only to abandon it as unworkable a few years later. Finally, there was Friedman the ideologue, the great popularizer of free-market doctrine.
Did the same man play all these roles? Yes and no. All three roles were informed by Friedman's faith in the classical verities of free-market economics. Moreover, Friedman's effectiveness as a popularizer and propagandist rested in part on his well-deserved reputation as a profound economic theorist. But there's an important difference between the rigor of his work as a professional economist and the looser, sometimes questionable logic of his pronouncements as a public intellectual. While Friedman's theoretical work is universally admired by professional economists, there's much more ambivalence about his policy pronouncements and especially his popularizing. And it must be said that there were some serious questions about his intellectual honesty when he was speaking to the mass public.[...]
During the first half of that fifty-eight-year stretch, from 1947 to 1976, Milton Friedman was a voice crying in the wilderness, his ideas ignored by policymakers. But the economy, for all the inefficiencies he decried, delivered dramatic improvements in the standard of living of most Americans: median real income more than doubled. By contrast, the period since 1976 has been one of increasing acceptance of Friedman's ideas; although there remained plenty of government intervention for him to complain about, there was no question that free-market policies became much more widespread. Yet gains in living standards have been far less robust than they were during the previous period: median real income was only about 23 percent higher in 2005 than in 1976.[...]
In the aftermath of the Great Depression, there were many people saying that markets can never work. Friedman had the intellectual courage to say that markets can too work, and his showman's flair combined with his ability to marshal evidence made him the best spokesman for the virtues of free markets since Adam Smith. But he slipped all too easily into claiming both that markets always work and that only markets work. It's extremely hard to find cases in which Friedman acknowledged the possibility that markets could go wrong, or that government intervention could serve a useful purpose.
Read the whole thing, which is not merely a remember of Milton Friedman, but a guide to some of the most contentious economic debates and questions of the post-war era.
