From the Comments: Money, Currency, and Bitcoins

Dr Gibson chimes in on Chhay Lin‘s most recent post about bitcoins (I hope there will be more):

“Unspent dollars means reduced sales, and as sales decline, profits drop, layoffs increase, and the total social income decreases, making less money available for consumption. Hoarding induces more hoarding as the economy sinks into a downward spiral.” (Smith, 2009)

That’s a lot of nonsense in just two sentences. (Note this is Smith’s paraphrase of the anti-hoarding argument, which he ably disputes.)

First, there is no distinction between “spent” and “unspent” dollars. Money jumps instantly from one pocket to another whenever it is used in a transaction. All money is “idle” between jumps. This could refer to the demand to hold money which is the inverse of the velocity of money. We hold money for convenience, safety, and occasionally as a hedge against deflation.

Second, decreased velocity means price deflation, other things being equal, and if a fall in velocity happens suddenly and unexpectedly, it can be a temporary boon to buyers and a detriment to sellers. But the idea of a deflationary spiral feeding on itself is silly, if only because we all have to eat. Low prices are the cure for low prices, as bargain-hunters move in and prices stabilize.

Then there’s this “social income” phrase. Real social income is not enhanced by faster spending. It is enhanced by greater productivity which depends on private saving, which in turn depends largely on property-friendly institutions. We cannot spend our way to prosperity.

I’ll also comment on Kaminska’s claim that bitcoins “do not benefit the economy” because they do not bear interest. Along with currency and (in their time) gold and silver coins, bitcoins are what economists call “outside money” meaning they are an asset that is no one’s liability. Checking account balances are a form of “inside money” because they are at once an asset of the account holder and a liability of the bank. When outside money is deposited in a fractional-reserve bank where it becomes inside money, some is kept in reserve and some is loaned out. This apparently what is meant by “benefit to the economy” but in fact it’s a benefit to the bank which can earn profits on the new loans and to the borrower, if all goes well. It’s a detriment to the rest of us because there is an increase in the money supply which causes price inflation.

There is nothing anti-social about holding outside money. Some of us see marginal benefits in holding outside money (security, convenience) that exceed the cost in foregone interest. So what?

My own two cents on this (get it?) is merely that Dr Gibson needs to spend more time at NOL fixing the mistakes of financial journalists and keeping his fellow economists honest. (Notereaders and Notewriters, holla at me and Warren in the ‘comments’ threads if you agree!)

  1. Thanks for the compliment, Brandon, but another insight of economics applies here: opportunity cost, sometimes phrased as “instead of what?” Time spent writing posts is time not spent on cleaning the garage or hiking in the woods or attending a concert or who knows what. Still, I’ll keep your comments in mind and be alert to opportunities to say something succinct but worthwhile, trusting that others will do the same.

Please keep it civil (unless it relates to Jacques)
