Study Notes on Financial Assets, Interest Rates, and Bond Prices

Definition: Financial assets are places where individuals can house their wealth, and they come with unique advantages and disadvantages.

Definition: Stocks represent ownership in a corporation.
Example: Holding 5,000 shares of General Motor stock purchased before bankruptcy.
Purpose: Investors buy shares in hopes that their value will increase over time as the company becomes more valuable.

Definition: Bonds are loans made to a corporation or government by the bondholder.
Mechanism: The purchaser of a bond is lending money, which will be repaid with the original value (principal) plus interest over time.
Example: A railroad bond sold in 1893 for $1,000 with a coupon payment of $50 annually ($25 semi-annually).
Equilibrium Interest Rate: In 1893, the bond represented a 5% interest rate as the coupon payment of $50 is 5% of $1,000.

Definition: Money is a liquid financial asset that can be used immediately to purchase goods and services.
Forms: Can be in the form of checking or savings accounts or physical currency (cash, coins).
Liquidity Comparison: Currency is the most liquid asset as it can be used immediately for transactions.

Definition: There exists an inverse relationship between bond prices and interest rates.
Example 1: In 1920, if the equilibrium interest rate increased to 10% (up from 5%), the bond price changes as follows:
- Original bond price was $1,000 and paid $50 annually.
- New bond price must drop to $500, because $50 is 10% of $500.
Example 2: In 1940, if the interest rate fell to 2.5%, the bond price must adjust:
- The bond still pays $50 yearly.
- To yield 2.5%, the bond price must increase to $2,000, since $50 is 2.5% of $2,000.
Summary Statement:
- When interest rates fall, bond prices increase.
- When interest rates rise, bond prices fall.

Interest rate changes can stem from conditions in the loanable funds market or the money market.
These concepts will further be discussed in upcoming lessons.

Bonds: Bonds generate interest income; for example, the previously mentioned bond pays $50 yearly.
Money: Money itself does not earn interest, which implies that holding money has an associated opportunity cost.
- Example: Holding assets in cash means foregone interest earnings that could have been obtained from investing in bonds.
Economic Choice: Deciding to hold wealth in money rather than in interest-bearing assets (like bonds) incurs an opportunity cost, defined as the equilibrium interest rate.
Money Market Dynamics:
- Demand for money is depicted through a downward sloping graph, illustrating the inverse relationship between interest rates and the quantity of money demanded.
- Higher equilibrium interest rates lead to lower demand for money as individuals prefer to purchase interest-bearing assets (e.g., bonds).
- Conversely, lower interest rates lead to increased demand for money as liquidity preferences rise, prompting individuals to utilize cash for transactions rather than bonds.

A strong understanding of the relationship between bond prices and interest rates is crucial for mastering concepts relevant to AP Macroeconomics exams.
The decision on how to hold wealth (in bonds or in liquid money) involves weighing interest earnings against liquidity preferences.
