Introductory Economics

Concept: Economics is broadly divided into two branches based on the level of analysis:

• Microeconomics
• Macroeconomics

Microeconomics: Microeconomics studies individual economic units such as consumers, firms, and industries.
Focus:

• Individual price determination
• Consumer behavior
• Firm production and cost
• Market structures (perfect competition, monopoly)

Examples:

• Price of a commodity
• Demand for a product
• Output of a firm

Macroeconomics: Macroeconomics studies the economy as a whole and deals with aggregate variables.
Focus:

• National income
• Inflation
• Unemployment
• Economic growth
• Fiscal and monetary policy

Examples:

• GDP of a country
• General price level
• Overall employment level

Key Differences:
Conclusion: Microeconomics explains how individual decisions are made, while macroeconomics analyzes overall economic performance and policy impacts.
