Money and banking chapter 2
Introduction to Money
Money has various forms and functions across different contexts, including prisons where cigarettes serve as a form of currency.
Understanding the general functions of money is important, especially in reference to commonly used currency like the US dollar.
Functions of Money
Medium of Exchange
The primary function of money is to serve as a medium of exchange.
Example: US dollar allows transactions without needing to barter.
Without money, trade becomes inefficient, requiring people to negotiate exchange rates (barter economy).
Unit of Account
Money functions as a unit of account, providing a standard numerical value for goods and services.
Price tags at stores indicate the value of items, simplifying transactions.
It allows individuals to measure the value of various goods/services consistently.
Store of Value
Money acts as a store of value, enabling individuals to save and defer consumption until a later time without losing value.
Example: Unlike perishable goods (e.g., bananas), money does not spoil and retains its purchasing power over time.
This function promotes the ability to time purchases effectively, unlike commodities that may require immediate use.
Implications of Money Functions
All forms of money should ideally serve these three functions. While different items can act as money (like bananas or cigarettes), traditional fiat currency (e.g., US dollar) provides an efficient solution for all three functions.
If given a scenario, students should be able to identify which function of money is being demonstrated.
Learning Activity
Engaging class activities help reinforce understanding of the functions of money.
Example scenarios are used in class to foster participation and comprehension of these functions.
Students should feel encouraged to discuss and clarify their understanding of money-related concepts.
Transition to Liquidity
Understanding liquidity is essential in finance, related to how easily an asset can be converted to cash.
Cash is considered highly liquid, while other assets (like real estate) are less liquid due to conversion time.
Evolution of Payment Systems
Commodity Money
Initially, various tangible goods served as money, including salt and cocoa beans, valued for their divisibility and standardization.
Drawbacks include cumbersome transportation.
Fiat Money
Transitioned to paper currency (fiat money), which has no intrinsic value but is accepted due to government decree.
Fiat money is legal tender for all debts but can be stolen or counterfeited.
Checks and Digital Payments
The invention of checks provided a more secure payment method than carrying large amounts of cash.
Modern payment methods include debit cards and digital transactions (e.g., Apple Pay, PayPal) which further enhance convenience.
Cryptocurrency and Economic Discussion
Bitcoin is primarily mentioned as a novel form of currency and investment.
The volatility of cryptocurrencies raises debates about their validity as a stable form of money.
Economists generally regard Bitcoin as a speculative investment rather than a reliable currency for the unit of account or store of value.
Measurement of Money by the Federal Reserve
M1 and M2
M1 consists of currency, checks, and demand deposits (most liquid).
M2 includes everything in M1 plus savings accounts and mutual funds (less liquid than M1).
Monitoring M1 and M2 growth helps the Federal Reserve determine monetary policy effectiveness.
Introduction to Interest Rates
Understanding interest rates is crucial as they influence saving, borrowing, and investment decisions.
Definitions such as present value are foundational for assessing future monetary needs.
The principle that a dollar today is more valuable than a dollar in the future needs to be emphasized, connecting back to saving strategies and investment decisions.
