Gresham's Law

Definition

Gresham's Law states that 'bad money drives out good money' in circulation. This principle explains how, when two forms of currency are used, the one that is perceived as less valuable tends to circulate more actively, while the more valuable currency is hoarded or taken out of circulation. The law highlights the dynamics of metal currency and coinage, especially in economies where different types of coins or currencies coexist.

Review Questions

• How does Gresham's Law illustrate the behavior of currency holders in an economy with both good and bad money?
  • Gresham's Law shows that in an economy with both good and bad money, people tend to spend the bad money while hoarding the good money. This happens because individuals want to preserve their wealth and are aware that good money has more intrinsic value. Consequently, this behavior leads to a situation where the valuable currency becomes scarce in circulation, affecting the overall economic dynamics.
• Evaluate the implications of Gresham's Law on monetary policy and currency management in modern economies.
  • Gresham's Law has significant implications for monetary policy as it underscores the importance of managing currency effectively to prevent devaluation. If a government allows the circulation of lower-quality currency alongside a stable one, it risks undermining trust in the monetary system. This can lead to inflationary pressures if citizens prefer spending the lower-quality money while hoarding what they perceive as more valuable assets, thereby complicating economic stability.
• Discuss how Gresham's Law might apply to contemporary digital currencies compared to traditional fiat money.
  • In today's economy, Gresham's Law can be observed in the relationship between digital currencies and traditional fiat money. As individuals recognize certain digital currencies as having more stability or potential value, they may choose to hold onto them instead of spending them. Meanwhile, they might use fiat currencies for everyday transactions. This situation could create an environment where less valuable or unstable digital currencies circulate more widely, while those considered 'better' are held back, echoing Gresham's principle in a modern context.
