Principles of Microeconomics - Chapter 4: Labor and Financial Markets

Vocabulary flashcards covering key definitions and supply and demand principles in labor and financial markets based on OpenStax Principles of Microeconomics 3e Chapter 4.

Labor Market

The supply and demand for labor.

Law of Demand in Labor Markets

The economic principle stating that a higher salary or wage (price) in the labor market decreases the quantity of labor demanded by employers, while a lower salary or wage increases the quantity of labor demanded.

Law of Supply in Labor Markets

The economic principle stating that a higher price for labor leads to a higher quantity of labor supplied, while a lower price for labor leads to a lower quantity supplied.

Labor Market Equilibrium

The situation in a labor market where the quantity of labor supplied equals the quantity of labor demanded, allowing employers to find workers and workers to find jobs at the equilibrium wage.

Minimum Wage

A price floor that makes it illegal for an employer to pay employees less than a certain hourly rate.

Living Wage

The amount a full-time worker would need to make to afford the essentials of life: food, clothing, shelter, and healthcare.

Financial Capital

Economic resources measured in terms of money, supplied through savings and demanded through borrowing.

Interest Rate

The "price" of borrowing in the financial market, or a rate of return on an investment.

Usury Laws

Laws that impose an upper limit on the interest rate that lenders can charge.

Intertemporal Decision Making

Deciding when to consume goods: now or in the future.

Technological Impact on Skill-Based Wages

Technological changes shift the demand for low-skill labor to the left ($D_0$ to $D_1$) as technology replaces workers, lowering wages. Conversely, new technology shifts demand for high-skill labor to the right ($D_0$ to $D_1$) in fields like IT, raising wages.

Living Wage Price Floor Impact

Imposing a wage floor at $\$12/\text{hour}$ above the equilibrium wage of $\$10/\text{hour}$ creates an excess supply of labor, where quantity supplied ($1,600$) exceeds quantity demanded ($700$).

Credit Card Interest Rate Price Ceiling

A price ceiling set at interest rate $R_c$ below the equilibrium interest rate $R_0$ prevents rates from adjusting upward, creating excess demand or a shortage where quantity demanded $Q_d$ exceeds quantity supplied $Q_s$.

Effect of Growing U.S. Debt on Capital Supply

When foreign investor enthusiasm diminishes, the supply of financial capital shifts to the left ($S_0$ to $S_1$), shifting equilibrium from $E_0$ to $E_1$ with a higher interest rate ($R_1$) and a lower quantity of financial investment ($Q_1$).

Role of Price Controls on Market Signals

Price controls deprive buyers and sellers of critical price information revealed through market behavior, making it difficult for economic actors to react properly to changing market conditions.
