What are the key differences between macroeconomics and microeconomics and how do they impact the overall economy?

Macroeconomics focuses on the economy as a whole, looking at factors like inflation, unemployment, and economic growth. Microeconomics, on the other hand, studies individual markets and how consumers and businesses make decisions. The two disciplines are interconnected, as microeconomic decisions can impact macroeconomic outcomes. Understanding both is crucial for policymakers to make informed decisions that can influence the overall economy.
