- Business Cycle: Model for evaluating U.S. market economy health.
- Phases: Expansion, Peak, Contraction, Trough.
- Economists can only predict transitions.
- Economic Indicators: Benchmarks for economic health.
- Examples: Employment, GDP, Stock Market, Capital Goods Purchases.
Phases of the Economy
- Expansion Phase: Economy growing.
- Goods & services sold, job growth, consumer confidence high, bullish stock market.
- Contraction Phase: Economy declining.
- Declining production, layoffs, increased consumer saving, bearish stock market.

- Max production and employment reached.
Economic Indicators
- Leading Indicators: Fast changing, early warning signs (e.g., stock market).
- Lagging Indicators: Slow changing, long-term effects (e.g., unemployment rate).
Gross Domestic Product (GDP)
- Measures the dollar value of all final goods & services produced in one year.
- GDP = Consumption + Investments + Government \, Spending + Net \, Exports
- Real GDP: Measures production, removing price distortion (inflation).
Unemployment
- Natural Unemployment Rate: Always a percentage of the population unemployed (normal < 5%).
- Measurement: Civilian Labor Force (16+ actively seeking employment).
- Formula: Unemployment \, Rate = \frac{Number \, of \, Unemployed}{Total \, Labor \, Force}
- Types:
- Seasonal: Jobs available only certain times of year
- Structural: Skills don't match job market.
- Frictional: Temporarily unemployed by choice.
- Cyclical: Follows the business cycle.
Inflation
- Persistent rise in prices, outpacing income.
- Measured by the Consumer Price Index (CPI).
- Demand-Pull Theory: Demand > supply causes prices to rise.
- Cost-Push Theory: Production costs rise, causing prices to rise.
- Hyper-inflation: Too much money in the economy.
- Stagflation: Rising prices, contracting economy.
Government Economic Theories
- Supply-side Economics: (Reaganomics) Lower taxes stimulate investment and job creation.
- Keynesian Economics: Government creates demand via spending and programs.
