Review Questions

• How does an increase in the quantity of a currency affect its exchange rate and what implications does this have for international trade?
  • An increase in the quantity of a currency typically leads to depreciation of that currency's exchange rate, making it less valuable compared to other currencies. This depreciation means that goods priced in that currency become cheaper for foreign buyers, potentially increasing exports. However, it can also make imports more expensive, leading to higher costs for consumers and businesses relying on foreign goods.
• Evaluate how central banks use the concept of quantity of currency in their monetary policy to achieve economic stability.
  • Central banks monitor the quantity of currency as part of their monetary policy framework to maintain economic stability. By adjusting interest rates or engaging in open market operations, they can influence the money supply. A well-managed quantity helps control inflation, fosters sustainable economic growth, and stabilizes the currency's value against others, ensuring that it supports both domestic and international economic activity.
• Analyze the relationship between currency quantity and inflation, focusing on how excessive increases can destabilize an economy.
  • Excessive increases in the quantity of a currency can lead to inflationary pressures within an economy. When more money chases the same amount of goods and services, prices tend to rise. This situation erodes purchasing power and can create uncertainty among consumers and businesses, negatively affecting investment decisions. If unchecked, high inflation can result in hyperinflation, leading to severe economic instability and loss of confidence in the currency itself.
