Economics: Microeconomics and Macroeconomics

Based on the notes, the main differences between microeconomics and macroeconomics lie in their scope and focus:

1. Level of Analysis:

   • Microeconomics studies issues occurring at the firm or individual level.
   • Macroeconomics focuses on economy-wide forces that impact multiple or all sectors.

2. Key Variables:

   • Microeconomics is concerned with specific factors like supply, demand, and pricing for particular products or services (e.g., setting prices for athletic club memberships).
   • Macroeconomics tracks broader indicators such as national income levels, unemployment rates, and inflation rates.

3. Decision-Making Focus:

   • Microeconomic decisions involve internal business operations, such as offering new product lines or investing in employee training.
   • Macroeconomic decisions involve predicting how large-scale conditions, like interest rates or global economic crises (e.g., the Great Recession), will influence the business's overall timing for expansion or borrowing.
