Review Questions

• Explain how the use of debit cards can impact the M1 money supply.
  • Debit cards are considered part of the M1 money supply because they represent a readily available form of money that can be used for transactions. When consumers use debit cards to make purchases, the funds are immediately withdrawn from their checking accounts, which are a component of M1. This can affect the overall size of the M1 money supply, as the amount of money available for immediate transactions is reduced.
• Describe the relationship between debit card usage and the M2 money supply.
  • The use of debit cards can also impact the M2 money supply, which includes not only the M1 components but also savings accounts and other less liquid forms of money. When consumers use debit cards to make purchases, the funds are withdrawn from their checking accounts, which are part of M1. However, if the funds are then replenished from savings accounts, which are included in M2, the overall size of the M2 money supply may be affected. The relationship between debit card usage and M2 is more indirect, as it depends on how consumers manage their various account balances.
• Analyze the role of debit cards in the decline of physical currency usage and the implications for the broader economy.
  • The widespread adoption of debit cards has contributed to a decline in the use of physical currency, as more consumers opt for the ease and convenience of electronic payments. This shift away from cash has several implications for the broader economy. First, it reduces the overall demand for physical currency, which can impact the central bank's ability to control the money supply and influence monetary policy. Additionally, the increased use of electronic payments can lead to greater efficiency and reduced transaction costs, but it also raises concerns about data privacy and the potential for financial exclusion of those without access to digital banking services. The decline in cash usage also has implications for certain industries, such as the retail and transportation sectors, which have traditionally relied on cash-based transactions.
