Monetarists

Monetary history of the United States

Monetarists argued that central banks sometimes caused major unexpected fluctuations in the money supply. Friedman asserted that actively trying to stabilize demand through monetary policy changes can have negative unintended consequences. In part he based this view on the historical analysis of monetary policy, A Monetary History of the United States, 1867–1960, which he coauthored with Anna Schwartz in 1963. The book attributed inflation to excess money supply generated by a central bank. It attributed deflationary spirals to the reverse effect of a failure of a central bank to support the money supply during a liquidity crunch. In particular, the authors argued that the Great Depression of the 1930s was caused by a massive contraction of the money supply (they deemed it "the Great Contraction"), and not by the lack of investment that Keynes had argued. They also maintained that post-war inflation was caused by an over-expansion of the money supply. They made famous the assertion of monetarism that "inflation is always and everywhere a monetary phenomenon."
