1. Introduction to Macroeconomics
Macroeconomics studies the economy as a whole, focusing on factors that affect the overall level of economic activity. It examines topics such as inflation, unemployment, economic growth, and international trade.
Key macroeconomic concepts include gross domestic product (GDP), inflation rate, unemployment rate, and interest rates. These indicators provide insights into the health and performance of an economy.
Real-World Examples of Macroeconomic Phenomena

GDP is divided into four main components:
- Consumption: Spending by households on goods and services.
- Investment: Spending by businesses on new capital and equipment.
- Government spending: Spending by government agencies on goods and services.
