Review Questions

• How does currency function as a medium of exchange and what implications does this have for money supply and demand?
  • Currency functions as a medium of exchange by allowing individuals to trade goods and services efficiently without the need for barter. This capability simplifies transactions, increases market participation, and influences the overall money supply and demand dynamics. When more currency is available in circulation, it can lead to increased spending, which drives demand; however, if too much currency is printed, it can result in inflation, diminishing its value.
• Discuss the role of central banks in managing currency and how their actions impact the money supply.
  • Central banks manage currency by implementing monetary policy to control the money supply through tools such as interest rate adjustments and open market operations. By increasing or decreasing the amount of currency available in the economy, central banks can influence inflation rates and economic growth. When they raise interest rates, borrowing costs increase, reducing the money supply; conversely, lowering rates encourages borrowing and increases currency circulation. This management is crucial for maintaining economic stability.
• Evaluate the relationship between currency value fluctuations and international trade in the context of money supply.
  • The relationship between currency value fluctuations and international trade is complex, as changes in a currency's value can significantly affect trade balances. When a country's currency strengthens, its exports become more expensive for foreign buyers, potentially reducing export demand; conversely, a weaker currency makes exports cheaper and more attractive abroad. This dynamic is further influenced by the overall money supply: an increase in money supply can lead to inflation, devaluing the currency and impacting trade competitiveness. Understanding this relationship helps analyze global economic interactions.
