Money as a store of wealth

Nick Rowe has a post that decries the idea of money as a store of value. He asks:

How much would I have been willing to pay for my house if the seller had imposed a condition that I could use it as long as I wanted but could never sell it again, or rent it out to someone else? Less than I paid for it, but still a positive amount. It yields a flow of services even if I can't sell that right.
How much would I have been willing to pay for the S20 note in my pocket if the seller had imposed a condition that I could use it as long as I wanted but could never sell it again, or rent it out to someone else? Nothing.
My response:

That's the same question a value investor asks before buying a stock.
The answer usually comes to something like, if I can pay $50 for a stock that is worth $100, then even though I can't resell it in the market I'll still buy it. Because the stock can't be resold, that $50 in value has to be realized through dividends. But if the stock is prohibited from ever paying a dividend, this value can still be realized by the firm repurchasing and canceling shares at higher prices.
I'd say roughly the same applies to central bank notes. If I can buy a note for far less than it's worth and hold it till the central bank begins to mop up the supply notes and cancel them, then I'll go ahead with the transaction. Since central banks are less opportunistic than firms and therefore less likely to announce buy backs, I'd only buy at a huge discount. A huge discount to what? The value of its bonds, bills, gold, buildings, and forex. In sum, the price I'd be willing to pay for non-transferable bank notes is not "nothing" but some number >0.
The store of value vs. medium of exchange argument is one of the oldest arguments in monetary economics. I don't think the answer is is binary, as in either/or. Rather, there is some sort of way to properly configure the two concepts into a logical whole. The answer would be a lot easier if the twin concepts medium of exchange and store of value were to be defined first in a microeconomic sense. In a sense, this sort of integration of monetary economics with microeconomics goes against the grain, since this would be making microeconomics more like monetary economics, and not vice versa, which has been the general approach taken by the whole microfoundations of money enterprise.

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...
