Measuring the Economy

Gross Domestic Product (GDP)

• Definition: Dollar value of all final goods and services produced within a country's borders in a year.
• Measurement Approaches:
  1. Expenditures Approach: C + I + G + Xn (Consumer spending, Investment, Government spending, Net exports)
  2. Income Approach: Wages + Rent + Interest + Profit
  3. Value Added Approach: Sum of value added at each production stage
• Included in GDP: Final goods and services, not intermediate or non-production transactions.
• Circular Flow Model: Demonstrates the flow of goods and services, and factors of production between households and businesses.

Limitations of GDP

• Exclusions: Intermediate goods, non-production transactions, used goods, illegal activities.

Unemployment

• Key Concepts:
  • Labor force, Labor force participation rate, Unemployment rate
• Types of Unemployment:
  1. Frictional: Between jobs
  2. Structural: Skills mismatch
  3. Cyclical: Due to economic downturns
• Natural Rate of Unemployment: Typically 4-6% in the U.S., includes only frictional and structural unemployment.

Inflation

Price Indices

• Consumer Price Index (CPI): Measures inflation using a market basket of goods.
• GDP Deflator: Measures price changes for all goods and services in the economy.

Concepts

• Inflation: General increase in prices.
• Deflation: General decrease in prices.
• Disinflation: Reduction in the rate of inflation.

Calculations

• CPI Calculation: Value of market basket in current year/base year * 100
• GDP Deflator Calculation: Nominal GDP/Real GDP * 100
• Issues with CPI:
  • Substitution bias
  • New products
  • Product quality

Costs of Inflation

• Hurt by Inflation:
  • Lenders with fixed interest rates
  • Fixed-income earners
  • Savers
• Helped by Inflation:
  • Borrowers
  • Businesses with prices rising faster than resource costs

Nominal vs. Real GDP

• Nominal GDP: Current prices
• Real GDP: Adjusted for inflation
• GDP Deflator: Used to convert nominal GDP to real GDP

Business Cycles

• Phases: Peak, Recession (Contraction), Trough, Expansion (Recovery)
• Recession vs. Recessionary Gap: Real GDP falling vs. GDP below potential GDP
