As all monetary economists know, in their book Friedman and Schwartz made the Depression a central case study in support of their contention that, historically, monetary instability has been a major source of fluctuations in the real economy. In their famous chapter on the ‘Great Contraction’, which was later released as a separate volume, Friedman and Schwartz attributed the collapse of production and prices in the United States particularly the disastrous 1931-33 slide to a precipitous decline in the U.S. money supply.
