Ron Paul's Money Illusion: The Sequel

David Andolfatto continues his battle with Ron Paul supporters:

Ron Paul's Money Illusion (Sequel), by David Andolfatto: As I promised to do here, I am posting a sequel to my original column: Ron Paul's Money Illusion. ... I ... hope that the nature of my criticism will be more clearly understood.

The purpose of my original post was to critique a statement I've heard Fed critics repeat ad nauseam. The statement can be found in Paul's book End the Fed (p. 25):

One only needs to reflect on the dramatic decline in the value of the dollar that has taken place since the Fed was established in 1913. The goods and services you could buy for $1.00 in 1913 now cost nearly $21.00. Another way to look at this is from the perspective of the purchasing power of the dollar itself. It has fallen to less than $0.05 of its 1913 value. We might say that the government and its banking cartel have together stolen $0.95 of every dollar as they have pursued a relentlessly inflationary policy.

I think that the first part of this statement is true, so I do not wish to dispute this fact. ... As for the final sentence in the quote above, well, I think it is just plain false. Now let me explain why...

Let me begin with the picture most popular with end-the-fed types--a graph depicting the declining purchasing power of the USD. I use postwar data without loss of generality, since most of US inflation has happened since then.

This picture plots the inverse of the price-level (as measured by the consumer price index). I have normalized the price-level to $1.00 in 1948. It falls to roughly $0.11 in 2010. This corresponds to roughly a nine-fold increase in the price-level or about a 4.6% annual rate of inflation. (Note that the rate of inflation has slowed considerably since 1980).

The picture above is used by some end-the-fed types to great effect in generating anger and fear among some members of the population. Anger via the claim that the Fed has stolen 90% of (the purchasing power) of your money; and fear through the prospect of this purchasing power approaching zero in the not-too-distant future. ...

Let me draw you another picture. This one plots the inverse of the U.S. nominal wage rate (total nominal wage income divided by aggregate hours worked).
This graph plots the purchasing power of the USD, where purchasing power is now measured in terms of labor, rather than goods. This graph shows that you need a lot more money today than you did in 1948 to purchase 1 hour of labor. Another way of saying this is that the average nominal wage rate in the U.S. has increased by a factor of 25 since 1948. ...

Let me now combine the two graphs above into one picture, with both series inverted, and with both the price-level and nominal wage rate normalized to $1.00 in 1948 (the actual nominal wage rate was $1.43).

According to these (publicly available) data, the price-level (CPI) has increased by about a factor of 10 since 1948. But the average nominal wage rate has increased by a factor of 25. (There is, of course, considerable disparity in wage rates across members of the population. But I am aware of no study that attributes significant wage or income heterogeneity to monetary policy. Of course, if readers know of any such studies, I would be grateful to have them sent to me.)

The figure above implies that the real wage (the nominal wage divided by the price-level) has increased by a factor of 2.5 since 1948. This is undoubtedly a good thing because it implies that labor (the factor we are all endowed with) can produce/purchase more goods and services. More output means an increase in our material living standards (Though again, I emphasize that this additional output is not shared equally. ...)

Now, an interesting question to ask is how the picture above might have been altered if the price-level had instead remained more or less constant. ...

I suggested, in my original post, that there is reason to believe that under an hypothetical regime of price-level stability, the nominal wage rate in the graph above would instead have ended up increasing only by a factor of 2.5 (more or less)--the factor by which real wages actually rose. This is what I meant by my claim of long-run neutrality of the price-level increase; and it is also what I meant by Ron Paul's Money Illusion (which is subtly different than claiming the superneutrality of money expansion; more on this later).

Some evidence in favor of my "long-run neutrality view" is to be found in the time-path of labor's share of income (GDP):

I see no evidence in the data here that our higher price level today has whittled the share of income accruing to labor. Moreover, I see no evidence suggesting that episodes of high or low inflation are related in any systematic way to the resources accruing to labor. (In fact, I see some evidence of a rising labor share during the high inflation decade of the 1970s.) But perhaps other data tells a different story. If so, I'd like to see the data (i.e., instead of a short email claiming that I am wrong). ...
To conclude, I think that the ... assertion that "the Fed has stolen 95 cents of every dollar" I view as absurd. There are legitimate criticisms one could level at the monetary institutions of this country, but these are not some of them. ...
