Introduction to Economics is a course that provides an overview of the two main branches of economics: macroeconomics and microeconomics. Macroeconomics focuses on the behavior of the economy as a whole, such as economic growth, inflation, and unemployment. Microeconomics examines the behavior of individual economic agents, such as households and firms, and how they interact with each other in markets. The course covers topics such as supply and demand, market structure, and economic policy.
