Economics is a social science that studies how individuals, businesses, governments, and societies allocate limited resources to satisfy unlimited needs and wants. It analyzes the production, distribution, and consumption of goods and services.

The discipline is broadly divided into two primary branches:

1. Microeconomics

Microeconomics focuses on the actions of individuals and specific industries. It examines:

Supply and Demand: How prices are determined in a given market.

Consumer Behavior: Why people choose to buy certain goods over others based on their budget and utility.

Business Decisions: How companies determine output levels, pricing strategies, and workforce sizes to maximize profit.

2. Macroeconomics

Macroeconomics looks at the economy as a whole, both on a national and global scale. It examines:

Economic Growth: Measured by Gross Domestic Product (GDP).

Economic Indicators: Inflation, unemployment rates, and interest rates.

Policy & Stability: The impact of government fiscal policies (taxation and spending) and central bank monetary policies on the overall economy.

Key Concepts

Scarcity: The fundamental economic problem of having seemingly unlimited human wants in a world of limited resources.

Opportunity Cost: The value of the next best alternative that must be foregone to make a certain choice.

Incentives: The rewards or penalties that motivate economic actors to make specific decisions.
