Some Unpleasant Monetarist Arithmetic

Abstract

In his presidential address to the American Economic Association (AEA), Milton Friedman (1968) warned not to expect too much from monetary policy. In particular, Friedman argued that monetary policy could not permanently influence the levels of real output, unemployment, or real rates of return on securities. However, Friedman did assert that a monetary authority could exert substantial control over the inflation rate, especially in the long run. The purpose of this paper is to argue that, even in an economy that satisfies monetarist assumptions, if monetary policy is interpreted as open market operations, then Friedman’s list of the things that monetary policy cannot permanently control may have to be expanded to include inflation. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
