Review Questions

  • Explain how mobile payment apps relate to the concept of M1 in the context of measuring money.
    • Mobile payment apps are closely linked to the M1 money supply, which includes the most liquid forms of money, such as currency in circulation and demand deposits. These apps allow users to make transactions and payments directly from their mobile devices, effectively functioning as a digital extension of cash and demand deposits. As more consumers adopt mobile payment apps, the usage of these apps can influence the M1 money supply by facilitating the transfer of funds and affecting the overall liquidity of the money in circulation.
  • Analyze the role of mobile payment apps in the context of measuring the money supply through M2.
    • Mobile payment apps can also impact the M2 money supply, which includes M1 as well as less liquid forms of money, such as savings deposits and small-denomination time deposits. By providing users with a convenient platform to manage their finances, mobile payment apps can influence the way individuals hold and access their savings and other less liquid assets. For example, the ease of transferring funds between mobile payment accounts and traditional savings accounts can affect the overall composition and velocity of the M2 money supply. Additionally, the integration of mobile payment apps with various financial products, such as interest-bearing savings accounts, can impact the M2 money supply by altering the public's preferences and behavior regarding their money holdings.
  • Evaluate how the widespread adoption of mobile payment apps could potentially impact the measurement and management of the money supply, specifically in terms of currency and its role in M1 and M2.
    • The widespread adoption of mobile payment apps has the potential to significantly impact the measurement and management of the money supply, particularly in the context of currency and its role in M1 and M2. As more consumers rely on mobile payment apps for their transactions, the demand for physical currency may decrease, as users can make payments and transfers directly from their mobile devices. This shift away from cash could lead to a reduction in the currency component of M1, potentially altering the overall composition and dynamics of the M1 money supply. Furthermore, the increased usage of mobile payment apps may also affect the velocity of money, as digital transactions can happen more quickly and efficiently compared to cash-based transactions. This, in turn, could impact the measurement and interpretation of M2, which includes currency in circulation as well as other less liquid forms of money. Policymakers and central banks may need to adapt their approaches to monitoring and managing the money supply to account for the growing influence of mobile payment apps on the broader financial ecosystem.
