Microeconomics analyzes the economic behavior of individual consumers and firms in specific markets. It examines how supply and demand determine prices and outputs in these individual markets for goods and services. The key concepts in microeconomics include theories of consumer demand, production costs, profit maximization, and equilibrium price and quantity. Macroeconomics takes a broader view, analyzing the economy as a whole. It studies aggregate indicators such as GDP, unemployment and inflation. Key macroeconomic concepts include national income accounting, economic growth, fiscal and monetary policy. Both microeconomics and macroeconomics are important areas of study, as individual markets make up the overall economy.
