Historical Context
Gresham’s Law is named after Sir Thomas Gresham, a 16th-century English financier. The principle was first articulated in the context of coinage and monetary standards during the reign of Queen Elizabeth I. It describes the phenomenon where overvalued currency (bad money) circulates in the economy, while undervalued currency (good money) is hoarded or removed from circulation.
Types/Categories
- Good Money: Currency that retains its intrinsic value, often made of precious metals like gold or silver.
- Bad Money: Currency with a lower intrinsic value or debased currency, usually due to overproduction or lower metal content.
Key Events
- The 16th Century England: The debasement of coinage led to the prevalence of Gresham’s Law, as merchants preferred to hoard valuable coins and circulate those with less intrinsic value.
- The U.S. Silver Purchase Act of 1890: This act led to the circulation of overvalued silver dollars, pushing gold coins out of the economy.
- The Euro Introduction in 2002: The replacement of various national currencies with the Euro showcased aspects of Gresham’s Law in how people transitioned to and hoarded the new currency.
