The credit theory of money

  Over on the discussion board, Oliver and Antti suggest that I read two essays from Alfred Mitchell-Innes. Here are a few thoughts.  A British diplomat, Mitchell-Innes was appointed financial advisor to King Chulalongkorn of Siam in the 1890s as well as serving in Cairo. He eventually ended up in the British Embassy in Washington where he penned his two essays on money. The first, What is Money , attracted the attention of John Maynard Keynes, while the second essay, The Credit Theory of Money —which was written in 1914—expounded on his views. Both are interesting essays and worth your time. One of Mitchell-Innes's main points is that all money is credit. This may have been a controversial stance back in 1914, when people were still very much focused on metallic money, but I don't think anyone would find it terribly controversial today. If we look at the instruments that currently function as money, all of them are forms of credit, that is, they are obligations or "cred...

Gold regulators

While our modern monetary system certainly has plenty of detractors, one of its successes is that we no longer need the services of the local gold regulator . In the late 1700s, the job of a gold regulator was to assay gold coins to determine if they were of the appropriate weight and fineness, modifying (ie 'regulating') the coin if necessary. When he was done, the gold regulator stamped the coin with his seal of approval and put it back into circulation. The job of regulating coins may seem strange to us. But it was an ingenious way to cope with the lack of standardization that bedeviled monetary systems in the 1600 and 1700s, particularly in the colonies. There was no domestic supply of coins in North America back then, so settlers relied on a bewildering array of foreign coins as their media of exchange, each with its own weight and fineness, and most of poor quality. This included not only silver coins such as Spanish dollars, pistareens, and English crowns, but also a gam...

The ubiquitous Spanish dollar—a photo essay

"The head of a fool on the neck of an ass." That's how Londoners described the strange silver coin pictured above, which first appeared in Britain in 1797. Due to worries that Napoleon was about to invade the British Isles, a run had developed on the Bank of England. In response, Parliament allowed the Bank to refuse to redeem its notes with gold coins, but this had only resulted in an inconvenient shortage of coins. To remedy the shortage, the Bank of England decided to open its vault and put its hoard of silver coins into circulation. Complicating matters was the fact that these coins were not native shillings or pennies, but Spanish dollars, otherwise known as eight real pieces. As such, they had to be re-purposed into local currency. The Bank of England accomplished this task by stamping the head of King George III—the fool—on the neck of Charles IV of Spain—the ass—who occupied the obverse side of that era's version of the Spanish dollar. The Bank then declared t...

Chopmarks and other distributed verification methods

A 1795 Spanish dollar, minted in Mexico, with several chopmarks One of the most interesting things about bitcoin, ripple, and other cryptocurrencies is how they are maintained by a dispersed user base rather than some central issuing authority. These users (miners in the case of bitcoin, nodes for ripple) ensure that each "coin" is a legitimate member of the total population of cryptocoins comprising that particular ledger. They are what stand between good coin and bad coin. I've run into two historical cases of a dispersed method of policing of the quality of exchange media: the endorsement of bills of exchange and the chopmarking of silver coins. It may be worthwhile to explore these two cases. The Watchdog role The watchdog or verification function is an important one, especially in anonymous trade where the unlikelihood of a repeat meeting between buyer and seller increases the incentives to be dishonest and pass off lousy coin. Not-so-liquid goods, say sofas, are ins...
