Retrospectives: Friedman and Schwartz, Disaggregated

What was the contribution of Anna Schwartz to the landmark book she co-authored with Milton Friedman, A Monetary History of the United States, 1867–1960? A close examination of archival evidence suggests three primary contributions Schwartz made to the work, and to Friedman's career more generally. The first was meeting the classic challenge of quantitative economic history: going into the field to locate and collect archival data that had been assembled for purposes unrelated to economic research, and deciding how best to use that data. Second, Schwartz had a decades-long role as technical sounding board and shaper of the statistical approach taken in the book. Schwartz's third and arguably greatest contribution was to transform A Monetary History of the United States into a compelling narrative argument that made an impact far beyond the economics profession. Together, these findings show Schwartz to be a scholar who made significant and lasting contributions to monetary economics, economic history, and the broader field of economics.
