RIP Milton Friedman, who had, more than any other man, the credit for the superior performance of this nation's economy as depicted in the graph in the immediately preceding post.
As even Brad DeLong realized:
All five of the planks of the New Keynesian research program ...had much of their development inside the twentieth-century monetarist tradition, and all are associated with the name of Milton Friedman. It is hard to find prominent Keynesian analysts in the 1950s, 1960s, or early 1970s who gave these five planks as much prominence in their work as Milton Friedman did in his.
The importance of analyzing policy in an explicit, stochastic context and the limits on stabilization policy that result comes from Friedman (1953a). The importance of thinking not just about what policy would be best in response to this particular shock but what policy rule would be best in general--and would be robust to economists' errors in understanding the structure of the economy and policy makers' errors in implementing policy--comes from Friedman (1960). The proposition that the most policy can aim for is stabilization rather than gap-closing was the principal message of Friedman (1968). We recognize the power of monetary policy as a result of the lines of research that developed from Friedman and Schwartz (1963) and Friedman and Meiselman (1963). And a large chunk of the way that New Keynesians think about aggregate supply saw its development in Friedman's discussions of the "missing equation" in Gordon (1974).
Thus a look back at the intellectual battle lines between "Keynesians" and "Monetarists" in the 1960s cannot help but be followed by the recognition that perhaps New Keynesian economics is misnamed. We may not all be Keynesians now, but the influence of Monetarism on how we all think about macroeconomics today has been deep, pervasive, and subtle.
Amen. And we won't see his like again.
