Microeconomics vs. Macroeconomics

  • Microeconomics: Study of individual markets and players.
  • Macroeconomics: Study of the overall economy, including national income, economic growth, unemployment, inflation, and government policies.

What is Macroeconomics?

  • Focuses on economic aggregates like GDP, unemployment rates, and inflation.
  • Originated as a distinct field during the Great Depression.
  • Aims to understand large-scale economic phenomena and guide policy-making.

Importance of Macroeconomics

  • Understanding economic booms and busts.
  • Helps in decision making related to employment, government policies, and taxation.

Key Economic Goals

  1. Economic Growth: Continuously growing GDP.
  2. Limiting Unemployment: Keeping unemployment rates low.
  3. Stable Prices: Avoiding rampant inflation or deflation.

Key Economic Indicators

  • Gross Domestic Product (GDP): Measures the value of all final goods and services produced within a country.
    • Distinction between nominal GDP (not adjusted for inflation) vs. real GDP (adjusted for inflation).
    • Real GDP provides a more accurate picture of economic health.
    • Example: Greece's declining GDP from 2010 to 2013.
  • Unemployment Rate: Percentage of the labor force that is unemployed and actively seeking employment.
    • Types of Unemployment:
      • Frictional: Transitional unemployment as people change jobs.
      • Structural: Mismatch between skills and job requirements.
      • Cyclical: Due to economic downturns.
    • Natural rate of unemployment includes frictional and structural unemployment.
  • Inflation Rate: Measures the rate at which prices increase over time.
    • Excessive inflation or deflation can harm economic stability.
    • Inflation impacts purchasing power and business costs.

The Business Cycle

  • Describes the fluctuations in economic activity over time.
  • Phases: Expansion, peak, contraction, trough.
  • GDP, employment, and inflation serve as gauges.
  • Economic indicators help monitor the business cycle.

Government's Role

  • Economists debate the extent of government intervention to regulate economic speed.
  • Tools: Government spending, tax policies.
  • Goal: Achieve full employment and stable economy.

Conclusion
