Ignore the Keynesian Axis of EvilEconomics / Economic Theory Feb 26, 2013 - 11:49 AM GMT
Your points in the November 29 column on Paul Krugman and the Austrians makes good points, and I would like to make a few comments of my own.
I do believe that when one makes apocalyptic comments, one gets what he deserves if the predictions don't pan out. As you said, that does not mean the Austrians are wrong regarding money and inflation, but expansions of money, especially in the way that the Fed has gone about doing so, are going to have a number of effects, rising consumer prices being only one of them.
I also believe that some of the Austrians, when they predicted near-instant hyperinflation, should have known better. An expansion in the monetary base can lead to what Milton Friedman called the "pushing on a string" effect, as an expansion of bank reserves will not increase the amount of money in circulation (at least not significantly) if businesses and individuals are not borrowing.
This is not to say that the Law of Marginal Utility, as applied to money, is somehow invalidated. An expansion of money in circulation will mean that the value of the marginal unit – in this case, the dollar – will fall, which means more money will be necessary to complete monetary transactions. That is the straight Law of Marginal Utility, and it applies to money as much as it would to anything else that is scarce.
As Murray Rothbard points out in his book, America's Great Depression, the amount of money in circulation during the 1920s grew, and he terms that as "inflation." However, according to the Consumer Price Index of that time, consumer prices fell by roughly one percent a year, which the late Jude Wanniski used as "proof" that Rothbard was wrong when he claimed that the 20s was an inflationary period. What we witnessed was an apples-and-oranges kind of comparison, as most people (including most economists) generally are used to defining inflation as an increase in the government's CPI, but the Austrians would say that changes in the CPI would be the result of inflation and in our case, the result of the monetary policies of the Fed.
While both Austrians and the Monetarists would see inflation as a monetary phenomenon where changes in relative prices of goods and services occur because the value of money, which is used to denote those relative price relationships, changes as the supply expands and contracts. The Austrians take one step further, however, as they go beyond the quantity effects of increases in the amount of money and look at how these monetary increases change the relative prices of real goods. In other words, the significant effect of changing the amount of money in circulation is not necessarily the changes in consumer prices (although they will change over time relative to the money in circulation), but rather the effect that monetary changes will have upon the relationships of the value of real goods to each other.
This point is vital, for the Austrians hold in their business cycle theory that when the central bank manipulates the banking system to increase the amount of money in circulation, the larger effect is not in consumer price changes but rather the fact that relative values of real goods are changed in a way that directs longer-term investment into lines of production that would seem to be profitable but over time turn out not to be. We certainly saw that in the housing boom and in the tech boom a decade earlier. Investments were directed into production lines that could not be sustained, given the preferences of consumers and their own financial constraints.
In the meantime, the actions of the central bank, when added to various policy initiatives by government, can create these booms that are unsustainable within a market setting and sooner or later are exposed by the markets themselves. When the meltdown became absolutely apparent in September 2008, we were seeing a situation where the market was declaring the mortgage securities held by Wall Street firms to be near-worthless.
(I would like to add a separate point here. Why is it that when a firm tries to manipulate the market to make an asset look more valuable than the market would say it is, authorities view that as being illegal, but when the Fed does it, as it is doing with its QE policies, that is considered "good for the economy"? After all, by purchasing billions of dollars of mortgage securities, the Fed is manipulating their values, given that the sheer purpose of Ben Bernanke's actions is to artificially raise security prices, which is deemed criminal behavior if a private firm does it.)
Krugman has explained that these bubbles were due to nothing more than the failures of private markets, and that unless government regulators intervene, markets always will go over the cliff because, well, because markets are just like that. Yet, if one holds that price signals really do matter, then one would ask why all markets do not behave in the manner we saw. Why not an automobile bubble or a bubble gum bubble or a firewood bubble? Instead, Krugman wants to absolve the Fed, Freddie and Fannie, and the various government agencies that were pushing home ownership and refinancing through policies of having played any part whatsoever in the housing bubble, as he wants us to believe that the problems were due solely to what he and other Keynesians believe to be the inherent failures that automatically accompany market transactions.
Austrians, on the other hand, look for the cause-and-effect. Carl Menger, the original Austrian Economist, begins his classic 1871 Principles of Economics with: "ALL THINGS ARE SUBJECT to the law of cause and effect. This great principle knows no exception, and we would search in vain in the realm of experience for an example to the contrary." Why the "irrational exuberance?" Krugman holds to the Keynesian line of "animal spirits" of investors, but that is no cause at all. Why shouldn't "animal spirits" bid down the values? Do they believe that investors are irrational when bidding up asset prices, but are rational when bidding them down? The Austrians would say that Fed policies of driving down interest rates where they would greatly affect mortgage markets, along with the drive-people-into-home-ownership policies of the Federal government created huge incentives for the creation of the housing boom, which ultimately turned into a bubble, and then a huge bust.
Regarding the consumer price effects of the Fed's policy of spreading dollars around the world, we can see some price increases in various commodities, i.e. food and fuel. Those of us who purchase gasoline or go to the grocery story can attest to some very large price increases over the past five years, and farmers where I live tell me they are having to absorb large increases in the price of animal feed, fertilizer, and diesel fuel. While Krugman wants to explain away these changes as being driven purely by inherent "volatility" and economic growth in places like China, it would seem to me that large increases in the money prices of those things denominated worldwide in dollars just might be due to large increases in the amount of money being poured into these assets and lines of production.
There is one more point. The Fed has vastly increased its balance sheet and has been spreading dollars around the world, mostly to purchase "assets" that essentially have little or no value so that the holders of those assets do not have to take the necessary financial bath. Such actions would not necessarily result in a huge increases of consumer prices overall, but they would have the effect of directing real investment away from those lines of production that would be both profitable and sustainable. Whether it is protecting the banks or the "green investors" or governments that have spent themselves into financial oblivion, the Fed has stymied the recovery by forcing assets into production areas that are doomed to failure. The result is what we see around is in the anemic economic growth.
Where some of the Austrians went wrong was in assuming that all of the Fed's new money pumping would be channeled into the purchase of consumer goods, thus driving up their prices. We have to look at where the new money is going, not where we might think it is going.
