๐ What is Microeconomics?

๐ What is Macroeconomics?
Macroeconomics studies the economy as a whole. It looks at aggregate variables such as national income, unemployment, inflation, and economic growth. Macroeconomics seeks to understand the factors that determine the overall level of economic activity and to develop policies to promote stability and growth.
