George Selgin reviews Felix Martin's Money: The Unauthorized Biography

See Mammon Dearest. Excerpt:

"The aftermath of the worst financial crisis since the Great Depression is a good time for taking a hard look at money, that most basic of all financial institutions atop which all the rest teeter. As his book's subtitle suggests, Felix Martin, having taken such a look, reports, not with a flattering portrait, but with a warts-and-all unmasking.

Mr. Martin's good prose and eye for money's naughtier antics help to equip him for his task. Nor is he short of tales to tell, about money's little prank of masquerading as stone wheels in the western Pacific, its domestication by Greek kings, its adolescent kidnapping by crafty private bankers, its disastrous fling with John Law, and, finally, its post-2001 binge. Mr. Martin relates them all, and many others, with élan.

But in his eagerness to reveal truths to which others have been blind, Mr. Martin ends up exposing, not so much money's mysteries as his own incomprehension of it. He goes astray, first of all, in assuming that, because credit rather than barter came before money, money consists, not of any physical stuff, but solely of a more-or-less elaborate system of IOUs. But while simple societies may track and settle debts in many different ways, among relative strangers and throughout most of history monetary promises have been promises to pay some particular stuff, whether tobacco, metal discs, or engraved paper strips.

The distinction between monetary promises and the stuff promised is, admittedly, often muddied, as it was when Great Britain's pound sterling ceased to refer to any actual coin (gold guineas having been worth a bit more than £1), and when modern central banks turned their paper promises to pay gold into what one former New York Fed President dubbed "IOU nothings." But the fact that a Federal Reserve note is no longer a promise to pay anything doesn't make the dollar an "arbitrary increment on an abstract value scale" or "a unit of abstract, universally applicable economic value." When a diner sells me bacon and eggs for $4.99, that doesn't mean that bacon and eggs are worth $4.99, "universally" or otherwise. It means that to the diner they are worth less, and to me, more.

Mr. Martin's understanding of what economists have had to say about money is still more inadequate. With the phrase "Adam Smith and his school," he lumps together every thinker from John Locke and Bernard Mandeville to Friedrich Hayek, throwing some later mathematical economists in for good measure, and excepting only John Law, Walter Bagehot, and John Maynard Keynes. He then attributes to this homogenized mass "a vision of society in which economic value had become the measure of all things" together with a blindness to the "debt and financial instability" to which this crass vision leads.

Horsefeathers. The monetary theories of John Locke (Martin's unlikely heavy) didn't particularly impress Smith, though Locke's mercantilism did — unfavorably; and far from sharing Mandeville's identification of narrow self-interest ("private vices") with public virtue, Smith condemned it as "pernicious." No one aware of the English currency controversies that raged for decades after the Panic of 1825 could possibly hold English economists oblivious to financial turmoil. Finally (to cut a long list short), in saying that the Bank of England should serve as a lender of last resort, Bagehot was taking issue, not with his fellow economists, but with the Bank's short-sighted Directors.

If Mr. Martin's knowledge of the history of economics is less than reassuring, his choice of economic good guys, Bagehot apart, is downright scary. He has soft spots for the ancient Spartans, who (according to him) wisely chose to dispense with money and all the "impersonal and inhumane relations its use entailed," and for Lenin and his crew, who tried, unsuccessfully, to do the same. Another of Martin's heroes is John Law, the Scottish "projector" whose "System," implemented in France in 1720, was, according to Martin, "ingenious, innovative, and centuries ahead of its time." Just shy of three centuries, one is tempted to elaborate. (Law's "system" collapsed, catastrophically, in 1721.)

That a jaundiced view of both money and most expert thinking about it shouldn't lead to any novel proposal for its reform isn't surprising. Stopping shy of suggesting another stab at Sparta's convivial solution, Mr. Martin instead endorses the old-hat idea of making commercial banks keep reserves (of "abstract units," presumably) equal to their readily transferable liabilities. To be free of the bathwater of financial crises we must, in other words, give old-fashioned banking the old heave-ho.

A proper respect for the crucial role bank loans play in promoting economic growth — in industrialized countries still, but especially in developing ones — combined with a glance beyond the limited experience of a few countries ought to suffice to make anyone think twice about such a Procrustean (if lately de rigueur) remedy: Canada, for instance, which has a very highly developed banking system (and one that has, since 1987, been utterly-free of Glass-Steagall-like regulations separating commercial from investment banking), experienced neither bank failures nor insolvent-bank bailouts during the recent crisis; indeed it has had an almost uninterrupted record of financial stability since the mid-19th century. Scotland long boasted a similar record, with no central bank to look to for bailouts, and very little bank regulation of any kind, until English currency laws were thoughtlessly imposed upon it in 1845.

It happens that Adam Smith supplied an especially eloquent account of the workings and advantages of Scotland's once brilliant fractional-reserve banking system as he witnessed it in its formative years. That account can be found in Book II, chapter 2 of The Wealth of Nations. Alas, so far as Mr. Martin is concerned, Smith's real thoughts about money might as well be among the very deepest of its secrets."
