What is Microeconomics?
Microeconomics is the study of how individuals, households, and firms make economic decisions. It examines the behaviour of consumers and producers in specific markets, and how supply, demand and prices interact to determine what gets produced and consumed.
Microeconomics focuses on individual actors — consumers, workers, and firms — and how they respond to price changes and incentives. It's the foundation of understanding markets and competition.
