In between my more practical posts, once every week or so I'll do something on the idea of moneyness. Economists have known for a long time that the concepts of uncertainty and money are intimately intertwined. George Costanza knows this too. He holds a bunch of cash to deal with all eventualities... until his wallet blows up. I'll show how we can just as easily replace money with moneyness in this two-step with uncertainty.
Uncertainty is an uncomfortable feeling one endures when thinking about an unforeseeable future. One of the ways to shield oneself from uncertainty is to devote a certain portion of one's portfolio to "money" – dollar bills, bank deposits, and such. Because these money items are liquid, it will be relatively easy for their holder to offload them in the future should some unanticipated eventuality arise. Holding money therefore alleviates discomfort about the future. This is the same sort of service that a fire extinguisher provides. Though someone may never need their extinguisher, it comforts its owner by its mere presence. On the margin, individuals are always comparing the present value of the stream of "security and comfort" that money provides to the consumption goods or durable assets that money can buy.
The link between uncertainty and the demand for money has a long heritage. We can find this idea early on in the Marshallian tradition, for instance. In 1917 Arthur Pigou, a student of Marshall, wrote that any person would be anxious to hold money "to secure him against unexpected demands, due to a sudden need, or to a rise in the price of something that he cannot easily dispense with." On the margin, people could either hold money, spend it on consumption, or exchange it for a capital asset. "These three uses," wrote Pigou, "the production of convenience and security, the production of commodities, and direct consumption, are rival to one another." (The Value of Money, 1917)
In 1921, Fred Lavington explicitly described this very same link between uncertainty and money.
the stock of money held by a business man serves not only to effect his current payments but also as a first line of defence against the uncertain events of the future. (The English Capital Market, 1921)More explicitly, said Lavington, money provides its owner with a
return of convenience and security. His stock [of money] yields him an income of convenience, for it reduces the cost and trouble of effecting his current payments ; and it yields him an income of security, for it reduces his risks of not being able readily to make payments arising from contingencies which he cannot fully foresee. The investment of resources in the form of a stock of money which facilitates the making of payments is then in no way peculiar; it corresponds to the investment by a merchant in the office furniture which facilitates the dispatch of business, to the investment of the farmer in agricultural implements which facilitate the cultivation of his land, and indeed to investment generally.Like Pigou, Lavington emphasized the marginal choice between holding money, spending it on consumption, and investing it.
Resources devoted to consumption supply an income of immediate satisfaction; those held as a stock of currency yield a return of convenience and security; those devoted to investment in the narrower sense of the term yield a return in the form of interest. In so far therefore as his judgment gives effect to his self-interest, the quantity of resources which he holds in the form of money will be such that the unit of resources which is just and only just worth while holding in this form yields him a return of convenience and security equal to the yield of satisfaction derived from the marginal unit spent on consumables, and equal also to the net rate of interest.The most famous adopter of this idea was Keynes, a friend of Pigou's and, oddly enough, Lavington's teacher.
Because, partly on reasonable and partly on instinctive grounds, our desire to hold Money as a store of wealth is a barometer of the degree of our distrust of our own calculations and conventions concerning the future... The possession of actual money lulls our disquietude; and the premium which we require to make us part with money is the measure of the degree of our disquietude. (The General Theory of Unemployment, 1937)The link between uncertainty and money isn't confined to the Marshallian and Keynesian traditions. Erich Streisler (1973) quotes Carl Menger in Geld:
The amount of money which is used in actual payments constitutes only a part, and indeed a relatively small part, of the cash necessary to a people, and . . . another part is held (in order that the economy may function without friction) in the form of various reserves as a security against uncertain payments, which in many cases in fact are never realized.William Hutt, an Austrian "fellow traveler", described the prospective yield from money in a 1952 paper called the Yield from Money Held. According to Hutt, the value of money assets was "affected by reason of their being demanded for their 'liquidity,' i.e. for the medium of exchange services that they can perform." These monetary services that money assets provide are prospective – even though money isn't being used, much like a fire engine when there were no fires, it isn't lying idle. "The essence of all these services is availability," wrote Hutt.
Modern Austrian Hans Herman Hoppe provides a very sharp linkage between uncertainty and money holdings.
the investment in money balances must be conceived of as an investment in certainty or an investment in the reduction of subjectively felt uneasiness about uncertainty. ('The Yield from Money Held' Reconsidered, 2009)Nor is the Auburn side of the Austrian school the only to note linkage. Steve Horwitz, a free-banking Austrian, also gives expression to the link between money and uncertainty:
The connection between Hutt and Menger lies in recognizing that the availability services that money provides flow from it being the most saleable good. To be available to be exchanged for anything at any time requires that the good have the degree of saleability that Menger describes. The nature of Hutt's availability services is that they are a subjective return to holding an item that others also subjectively value a great deal, thus permitting the item to be easily exchangeable. When one chooses to hold wealth in the form of money, one is simply purchasing these availability services. (A Subjectvist Approach to the Demand for Money, 1990)We also find the link between uncertainty and money among monetarists. In their 1971 paper The Uses of Money, Brunner and Meltzer noted that in a world of perfect certainty, information is available for free. This effectively eliminates the main reasons for the existence of money. However, by relaxing the assumption of certainty, “transactors possess very incomplete information about the location and identity of other transactors, about the quality of the goods offered or demanded, or about the range of prices at which exchanges can be made.” Rather, they must acquire information about these characteristics. Because knowledge acquisition takes time and energy, individuals may alternatively:
search for those sequences of transactions, called transaction chains, that minimize the cost of acquiring information and transacting. The use of assets with peculiar technical properties and low marginal cost of acquiring information reduces these costs. Money is such an asset.David Laidler, also a monetarist, describes the money as a "buffer against costly consequences of market uncertainty and inflexibility".
If money holding is a cheap and reliable buffer, then agents will find that it pays to remain relatively uninformed about the processes affecting the variability of their net receipts, and will be relativley unwilling to undertake any costly measures that might render them either more predictable or controllable. If, on the other hand, money holding itself is a costly or unreliable source of insulation from such uncertainty, then the expenditure necessary to acquire and utilise extra information is more likely to be made. (Taking Money Seriously, 1990)It's clear from this wide variety of quotes that many economists have considered money holdings to be uncertainty-alleviating. It's not a big step to replace the concept of "money" with "moneyness". The idea here is that by selling less-liquid items for more-liquid items, individuals can increase their protection from uncertainty. All assets can be ranked on a scale according to their liquidity/moneyness, and as a corollary, by their ability to "lull our disquietude".
On the margin, people are constantly comparing the package of services provided by each asset in an economy, where each package consists of the real services the asset provides, its pecuniary returns (interest, capital gains, or dividends), and finally the extent to which that asset's moneyness shields the holder from uncertainty. This means that in trying to defray their worries about a cloudy future, people seek out the quality of moneyness rather than a specific instrument called money. This quality, or property, is never fully concentrated in one hypothetical asset called "money" but can be found unevenly distributed over the economy's entire range of goods.
To get up to speed, here are two previous posts dealing with the idea of moneyness
