New Analysis Shows Milton Friedman Massaged His Coin Render Information To Tally His Empirical Models

By Joseph T. Salerno

Austrians realize that empirical reality is unique, peculiarly raw statistical data.  Let that information travel massaged, averaged, seasonals taken out, etc. together with so the information necessarily falsify reality. — Murray Rothbard, Making Economic Sense, p. 246)

For many years I—and other Austrians—have had to suffer charges past times monetarists that Murray Rothbard fudged the information to growth monetary growth rates during the 1920s inward guild to portray it every bit an inflationary decade.  As I argued (here and here) inward an telephone commutation alongside eminent monetary historian Richard Timberlake (here, here, and here) these allegations are baseless.   So, forthwith it is alongside delicious irony that I depict your attending to an explosive article past times 3 econometricians thoroughly debunking the empirical claim made past times Milton Friedman together with Anna Schwartz (FS) that the velocity of coin inward the USA has exhibited long-run stability for to a greater extent than than a century leading upwardly to 1975.  

Neil Ericsson, David Hendry, together with Stedman Hood debate that dubious “data adjustment” inward FS’s empirical models “dramatically reduced apparent drive of the velocity of circulation of coin together with . . . adversely affected the constancy together with check of his estimated coin demand models.”  In other words, FS’s empirical illustration that the demand for coin (the inverse of velocity) is constant, which FS painstakingly elaborated inward 3 statistical tomes published from 1963 to 1982 together with which is the linchpin of monetarism, has been exposed every bit statistical legerdemain. 

FS adjusted the raw information to trouble concern human relationship for: 1. the abrupt attack of rapid developments of fiscal instruments together with institutions inward the USA economic scheme compared to the United Kingdom economy; together with 2. short-run fluctuations inward velocity associated alongside trouble concern cycles.   In adjusting for “changing fiscal sophistication,” Ericsson et al. indicate out, FS added a linear tendency of 2.5% on coin render observations prior to 1903, but made no tendency adjustment at all to the information later on that year.  In the process, they “adjusted” the coin stock for 1867 from its raw or unadjusted value of $1.28 billion to $3.15 billion.  This is a phantom growth of 246% on the observed coin stock!  The outcome of this tendency adjustment was to substantially suppress the outcome of the needlelike decline inward observed velocity of to a greater extent than than 50% from the early on 1870s to 1903 on its variability over the entire menstruation studied (1867-1975). Thus although the adjustment applies to exclusively 30% of the menstruation studied, it accounts for almost 75% of the total variance of velocity. (See the graph below.)

Ericsson et al. seat a serial of embarrassing questions ignored past times FS virtually the rationale for their adjustment procedure.  Why is

the lack of fiscal sophistication inward the USA judged alongside honour to that inward the United Kingdom rather than inward another country?  Why is a constant annual improvement of 2.5% considered appropriate?  What evidence is at that spot that the USA caught upwardly to the United Kingdom exactly inward 1903, fifty-fifty though the dollar’s international purpose continued to growth relative to that of sterling throughout the 1900s?  And, finally, why weren’t other economical variables potentially affected past times fiscal sophistication, such every bit involvement rates together with income, non adjusted?

FS too averaged or “smoothed” all annual information over phases of the trouble concern wheel (either inflation or recession).  This physical care for significantly reduced short-run fluctuations inward velocity, primarily inward the slowly 1870s-early 1880s together with during the Great Depression together with World War 2.  This enabled FS to debate that their “phase-average” models of monetary demand econometrically predict or “explain” to a greater extent than of velocity’s actual variations when compared to random walk models estimated on annual unadjusted data. Ericsson et al. counter that FS made a basic mistake of failing to trouble concern human relationship for their phase-averaging of the raw information when they calculated the “residual measure error,” that is, the variations inward velocity non explained past times the model. The measure errors of FS’s phase-average models must travel adjusted or “rescaled” to allow comparing alongside each other together with alongside models estimated on unadjusted data.  Once this correction is made, Ericsson et al. show, a random walk model on unadjusted annual information has a lower balance measure mistake together with explains “more than 30% of what FS’s models create non explain.”  This outcome resoundingly rejects FS’s “claim that USA velocity is reasonably constant.”  This is reinforced past times the fact that fifty-fifty FS’s adjusted velocity declines past times 50% from the 1870s to the 1940s. (See graph below.)

The authors acquaint other technical criticisms of FS’s empirical methods together with become on to conclude:

Friedman’s adjustment of the observed USA coin stock for fiscal sophistication greatly reduced the visually apparent non-constancy of velocity, but the resulting measured velocity is nonetheless highly non-constant, contrasting alongside Friedman’s claim that velocity was reasonably constant. . . . [U]nadjusted phase-average velocity varies past times a constituent of 3.9, together with fifty-fifty adjusted velocity past times a constituent of 2.2.  It would hence travel empirically misguided to base of operations policy analysis on the supposition that velocity is constant.

So despite arbitrarily adjusting, averaging, together with smoothing, i.e., fudging, the data, Friedman was unable to back upwardly i of the key claims of his life’s run that, as cited past times the Nobel Prize committee, “the demand for coin is inward fact real stable.”
