Hogeye> The advantage [of commodity money] is avoiding a situation where the issuer can arbitrarily increase the money supply.
Doug> You mean like cutting the money into pieces?
Cutting an oz of gold into 10 parts does not increase the total weight in gold. Obviously. It does
not increase the money supply. Similarly, printing 10 warehouse receipts for .1 oz gold to replace 1 warehouse receipt for 1 oz gold does not increase the money supply. Again, please don't equivocate total weight of a commodity with the number and size of containers its stored in.
Doug wrote:And history shows that gold doesn't really "back" any money. It was just a superstition.
On the contrary, gold (or some other commodity) has backed money for most of human history. In 19th century US, the money was generally warehouse receipts printed by private banks, redeemable in gold (gold or silver in the bi-metal days). This is a matter of record and a matter of fact. It wasn't until 1933 that the US stopped cashing in its notes for gold for its own citizens. It wasn't until 1972 that the US stopped redeeming its note for foreign central banks.
Doug wrote:It takes a decree for people to say that 1/2 a gold coin is now worth as much as 1 gold coin used to be.
No, the prices of bread, butter, chickens, etc. were bid up in varied and diverse individual one-on-one transactions, the sum total of which we call a "market." You seem to think all prices are fixed by decree, like the old Soviet system attempted. Why can't you tell a market result from a decree?
Hogeye> Each has half the weight in gold as before. But they can buy the same amount of goods.
Doug> How can they buy the same amount of goods? A hammer costs one gold piece, say. The next day it costs 1/2 of a gold piece because people cut their money in half? How is this supposed to happen?
David Hume explained this long ago. Suppose half the money people use in a society magically disappeared? What would be the effect on prices? They would be bid down. Similarly, if the money supply magically doubled, prices would be bid up. Neither would happen instantaneously; it would happen as buyers and sellers discovered shortages and surpluses. In our scenerio, where the amount of goods doubles, shopkeepers would notice that most of their hammers are not selling. People simply could not afford to buy all the hammers on sale at the current price. Shopkeepers (and hammer manufacturers, and iron and wood suppliers, all down the line) would notice that their replacement costs have diminished. To clear the market (shopkeepers not liking hammers for aethetic value, but as an income-generating trade item, and not wanting an unsalable item lingering on their shelves) cut their prices until supply equals demand. Eventually an equilibrium price is reached, roughly half the old
pre-doubling of goods price. In short, prices are bid down since you have the same amount of money (in weight!!!) chasing double the amount of goods. You say, "there are twice as many people so the demand stays the same." For goods, yes, but the demand for money (per oz!!!) has doubled. This is where one must keep in mind that money is just another commodity, with the same considerations applying.
That's the process - not a decree from on high, but an emergent process driven by many individual interactions on the basis of local conditions. An analogy: The water level in my teapot is the same in the main pot part and the spout. Is there a god decreeing, "Level thou water molecules," with the H2O obeying? No, on the contrary, the water molecules are acting according to their local conditions of other water molecules and air pressure. The
water seeks its level phenomena is the result of emergent order, not planned order.

This doesn't make sense. OTBE an ounce of gold in coin form is
more valuable than an ounce chunk of gold, since you'd have to assay the chunck to determine its purity whereas a known coin is "certified" by the mint. I strongly suspect, Barbara, that you are referring to the fixed price bimetal period. "When the price of specie was controlled," is a dead giveaway. Coins of the overvalued metal would disappear by Gresham's Law (
In a "legal tender" regime, bad money drives out good.)
Barbara wrote:Market fluctuation of the metal makes specie-backed paper very unstable.
We've been over this fallacy already - saying "gold is unstable as measured by the dollar" is saying exactly the same thing as "the dollar is unstable as measured by gold." It's symmetrical - they are equally unstable using the other as a measure. Obviously, you have to use something else, a third commodity or the general price level as a measure. Using these measures, specie is
much more stable than fiat money. Do I need to trot out my comparisons over time with chicken, beef, and shovels again?
