Why moneyness?


Here's why this blog is called Moneyness.

When it comes to monetary analysis, you can divide the world up two ways. The standard way is to draw a line between all those things in an economy that are "money" and all those things which are not. Deposits go in the money bin, widgets go in the non-money bin, dollar bills go in the money bin, labour goes in the non-money bin etc etc.

Then you figure out what set of rules apply specifically to money and what set of rules apply to non-monies (and what applies to both). The quantity theory of money is a good example of a theory that emerges from this way of splitting up of the world. The quantity theory posits a number of objects M that belong in the relation MV=PY. Non M's needn't apply.

The second way to classify the world is to take everything out of these bins and ask the following sorts of questions: in what way are all of these things moneylike? How does the element of moneyness inhere in every valuable object? To what degree is some item more liquid than another? This second approach involves figuring out what set of rules determine an item's moneyness and what set determines the rest of that item's value (its non-moneyness).

Here's an even easier way to think about the two methods. The first sort of monetary analysis uses nouns, the second uses adjectives. Money vs moneyness. When you use noun-based monetary analysis, you're dealing in absolutes, either/or, and stern lines between items. When you use adjective-based monetary analysis, you're establishing ranges, dealing in shades of gray, scales, and degrees.

In general, the first way of dividing the world has been overrepresented in the history of monetary discourse. I'd weight its prevalence at around 90%. Take Keynes's General Theory. Almost the entire book uses the noun-based approach to monetary analysis, except for Chapter 17 (and a small bit in Chapter 23). It's only then that Keynes describes the idea of a liquidity premium that inheres in all assets:
the power of disposal over an asset during a period may offer a potential convenience or security, which is not equal for assets of different kinds, though the assets themselves are of equal initial value. There is, so to speak, nothing to show for this at the end of the period in the shape of output; yet it is something for which people are ready to pay something.
In my posts I try to do two things. First, I make my best effort to always speak in the under-represented language of moneyness, not money. Not that there's anything wrong in splitting the world into money and non-money. But any method of dividing the universe will determine what one sees. Reclassify the universe along different lines and a whole new world emerges. With most monetary economics having been conducted in terms of money, there's probably a lot we've never seen.

Secondly, I hope to remind people that while you can choose either of the two ways to classify the world, you need to be consistent when you use them. Don't switch arbitrarily between the two.

With that being said, here are a few posts that illustrate the idea of moneyness.

3. Adam Smith: taxes contribute to fiat's liquidity premium, they don't drive its value

Stock as a medium of exchange

American Depository Receipt (ADR) for Sony Corp You've heard the story before. It goes something like this. There's one unique good in this world that serves as a universal vehicle by which we conduct every one of our economic transactions. We call this good "money". Quarrels often start over what items get lumped together as money, but paper currency and deposits usually make the grade. If we want to convert the things that we've produced into desirable consumption goods (or long-term savings vehicles like stocks), we need to pass through this intervening "money" medium to get there. This of course is fiction—there never has been an item that served as a universal medium of exchange. Rather, all valuable things serve to some degree or other as a medium of exchange; or, put differently, everything is money. What follows are several examples illustrating this idea. Rather than using currency/deposits as the intervening medium to get to their desired final...

Yap stones and the myth of fiat money

At first glance, the large circular discs that circulated on the island of Yap in the South Pacific certainly seem quite odd. Too big to be easily transported, the stones are often seen in photos resting against their owner's houses. So much for velocity. Yap stones have been considered significant enough that they have become a recurring motif in monetary economics. Macroeconomics textbooks, including Baumol & Blinder , Miles & Scott ( pdf ), Stonecash/Gans/King/Mankiw , Williamson , and Taylor all have stories about Yap stone money. Why this fascination? Part of it is probably due to the profession's obsession with the categorical divide between "money" and "non-money". In dividing the universe of goods into these two bins, only a few select goods end up in the money bin. That an object so odd and unwieldy as a three meter wide stone could join slim US dollar bills and easily portable silver coins in the category of money is pleasantly counterintu...

Chain splits under a Bitcoin monetary standard

The recent bitcoin chain split got me thinking again about bitcoin-as-money, specifically as a unit of account . If bitcoin were to serve as a major pricing unit for commerce on the internet, we'd have to get used to some very strange macroeconomic effects every time a chain split occurred. In this post I investigate what this would look like. While true believers claim that bitcoin's destiny is to replace the U.S. dollar, bitcoin has a long way to go. For one, it hasn't yet become a generally-accepted medium of exchange. People who own it are too afraid to spend it lest they miss out on the next boom in its price, and would-be recipients are too shy to accept it given its incredible volatility. So usage of bitcoin has been confined to a very narrow range of transactions. But let's say that down the road bitcoin does become a generally-accepted medium of exchange. The next stage to becoming a full fledged currency like the U.S. dollar involves becoming a unit of account...
