economics final review

Here’s a comprehensive breakdown of the economics vocabulary and concepts you’ve listed:

1. Factors of Production

The resources used to produce goods and services:

  • Land: Natural resources (e.g., water, minerals).
  • Labor: Human effort (physical/mental).
  • Capital: Tools/machinery (physical) or money (financial).
  • Entrepreneurship: Innovation/risk-taking to combine other factors.

2. Production Possibilities Frontier (PPF/PPC)

  • A curve showing maximum combinations of two goods an economy can produce with given resources.
  • Key Points:
    • Points on the curve = efficient production.
    • Inside = inefficient/unemployed resources.
    • Outside = unattainable without growth (e.g., more resources/tech).

3. Economic Systems

SystemWho Decides?Key Features
TraditionalCustoms/traditionsBarter, agrarian, slow change.
CommandGovernmentCentral planning, state ownership.
MarketIndividuals/businessesSupply/demand, private property.
MixedGovernment + individualsMost modern economies (e.g., U.S.).

4. Elements of the American Economy

  • Market Elements (6):
  1. Private property.
  2. Profit motive.
  3. Consumer sovereignty.
  4. Competition.
  5. Voluntary exchange.
  6. Limited government.
  • Command Elements (3):
  1. Public goods (e.g., roads).
  2. Regulations (e.g., FDA).
  3. Redistribution (e.g., welfare).
  • Mixed Economy: Combines market freedom with government intervention.

5. Demand

  • Law of Demand: Price ↑ → Quantity demanded ↓ (and vice versa).
  • Shifts vs. Movement:
    • Shift (change in demand): Caused by non-price factors (BRIDE).
    • Movement: Price changes cause movement along the curve.
  • BRIDE Shifters:
    • Buyers (number of).
    • Related goods (substitutes/complements).
    • Income (normal vs. inferior goods).
    • Demographics.
    • Expectations (future prices/income).
  • Elasticity:
    • Elastic: Quantity changes a lot with price (e.g., luxuries).
    • Inelastic: Quantity changes little (e.g., necessities like insulin).

6. Supply

  • Law of Supply: Price ↑ → Quantity supplied ↑.
  • Shifts vs. Movement:
    • Shift (change in supply): Non-price factors (GROOM).
    • Movement: Price changes cause movement along the curve.
  • GROOM Shifters:
    • Government (taxes/subsidies).
    • Resource costs.
    • Other goods’ prices.
    • Output (technology/productivity).
    • Market size (number of sellers).

7. Equilibrium

  • Where supply = demand; no surplus/shortage.
  • Price Signals: Surplus (price ↓) or shortage (price ↑) push market back to equilibrium.

8. Price Controls

  • Price Floor: Min price (e.g., minimum wage) → surplus.
  • Price Ceiling: Max price (e.g., rent control) → shortage.

9. U.S. Socioeconomic Goals

  1. Economic Freedom: Choice in work/spending.
  2. Economic Equity: Fair distribution (e.g., anti-discrimination laws).
  3. Economic Security: Safety nets (e.g., Social Security).
  4. Economic Efficiency: Maximize resource use.
  5. Economic Growth: Increase GDP over time.
  6. Full Employment: Low unemployment.
  7. Price Stability: Control inflation.

10. Market Structures

StructureFeaturesExample
Perfect CompetitionMany firms, identical products, no barriers.Agriculture.
Monopolistic CompetitionMany firms, differentiated products.Restaurants.
OligopolyFew firms, interdependent decisions.Airlines.
MonopolyOne firm, high barriers.Utilities (regulated).
  • Non-Price Competition: Advertising/branding (common in monopolistic competition/oligopoly).
  • Game Theory: Analyzes strategic decisions (e.g., oligopolies’ pricing).

11. GDP (Gross Domestic Product)

  • Total value of goods/services produced in a country in a year.
  • Measurement:
    • Expenditure Approach: C + I + G + (X – M).
    • Income Approach: Wages + rent + profit + interest.
    • Trump’s Proposal: Include intangible assets (e.g., R&D) to boost GDP.
  • Importance: Primary indicator of economic health.

12. Business Cycle

  1. Expansion: GDP ↑, employment ↑.
  2. Peak: Highest growth before contraction.
  3. Contraction/Recession: GDP ↓ (2+ quarters).
  4. Trough: Lowest point before recovery.
  5. Depression: Severe, prolonged recession.

13. Inflation

  • CPI (Consumer Price Index): Tracks urban household prices.
  • PCE (Personal Consumption Expenditures): Broader (includes healthcare).
  • Ideal Inflation: ~2% (Fed target).
  • Types:
    • Demand-Pull: Too much spending (demand > supply).
    • Cost-Push: Rising production costs (e.g., oil prices).

14. Interest Rates

  • ↑ Rates: Borrowing cost ↑ → consumer spending ↓.
  • ↓ Rates: Stimulates loans/spending.

15. Taxes
