Macroeconomics Unit 2: Economic Indicators

Presented by Jacob Reed from ReviewEcon.com


Overview

  • Focus on economic indicators.
  • Part of the total review booklet available at ReviewEcon.com.
  • Content accompanies existing resources for further study.

Circular Flow Model

  • Economic Actors: Households and Businesses.
  • Markets:
    • Product Market: Businesses supply goods/services; households provide money (sales).
    • Factor Market: Households supply resources (land, labor, capital, entrepreneurship); businesses provide wages, interest, rent, profit.
  • Mixed Economy (US Context):
    • Government as a third actor, interacting with both markets.
    • Provides public goods funded by taxes.

Gross Domestic Product (GDP)

  • Definition: Total value of all final goods/services produced within a country annually.
  • Calculation Methods:
    1. Value-Added Approach: Measures contributions of firms to final goods (e.g., fabric to shirt transformation).
    2. Income Approach: Counts money from businesses to households via rents, wages, interest, profit, with adjustments for taxes/depreciation.
    3. Output Expenditure Model:
      • Formula: C + I_g + G + X_n
      • C: Consumption (consumer purchases).
      • I_g: Gross Investment (business capital purchases and inventory changes).
      • G: Government Purchases.
      • X_n: Net Exports (exports - imports).

Non-Countable GDP Items

  • Used items, intermediate goods, financial transactions are excluded.
  • GDP Per Capita: Used to measure standard of living with noted inaccuracies (e.g., underground economy, home production, etc.).

Unemployment

  • Definition: Not working but actively seeking employment.
  • Unemployment Rate Formula: (Unemployed / Labor Force) x 100.
  • Labor Force Participation Rate: (Labor Force / Civilian Population) x 100.
  • Types of Unemployment:
    • Frictional: Between jobs or first-time job seekers.
    • Structural: Skill mismatches due to economic changes.
    • Cyclical: Due to economic downturns (business cycle).
    • Natural Rate of Unemployment: Frictional + Structural unemployment.

Inflation

  • Definition: General price level increase across the economy.
  • Measurement:
    • Consumer Price Index (CPI): Tracks household product price changes.
    • GDP Deflator: Tracks price changes across all products.
  • Calculation Concepts:
    • Nominal vs. Real GDP: Real adjusted for inflation.
    • CPI Calculation: [(Current Basket Value / Base Year Basket Value) x 100].
    • Inflation Calculation: [(New CPI - Old CPI) / Old CPI] x 100.

Effects of Inflation

  • Borrowers benefit from unexpected inflation; banks and savers are harmed.

Macroeconomic Goals

  • Economic Growth: Measured by GDP.
  • Full Employment: Low or natural rate of unemployment.
  • Stable Prices: Tracked by CPI or GDP deflator.

Business Cycle

  • Phases:
    • Expansion: GDP rises, unemployment falls.
    • Contraction: GDP falls, unemployment rises (recession if >6 months).
    • Peaks: High inflation.
    • Troughs: High unemployment, possible deflation.
  • Gaps:
    • Inflationary Gap: Output > Potential, leads to rising prices.
    • Recessionary Gap: Output < Potential, high unemployment.
  • Economic Growth: Long-term upward trend in potential output.

Conclusion

  • Comprehensive review of economic indicators and their implications.
  • Additional resources and activities available on ReviewEcon.com for further practice and study.
  • Encouragement to engage with additional study materials and support resources.
