What is Macroeconomics?
Macroeconomics is the study of the entire economy at the national or global level. It examines aggregate output (GDP), employment, inflation, interest rates, and the policies governments use to influence economic growth and stability.
Macroeconomics analyzes the behaviour of large economic groups — nations, regions, the world economy — focusing on total income, spending, and the forces that drive long-term growth and short-term fluctuations (recessions).

Common mistakes
Thinking a higher GDP is always better. — Correct: Unsustainable growth (via debt) can crash later; quality and distribution matter too.
Confusing nominal and real GDP. — Correct: Nominal = current prices; real = adjusted for inflation (true economic growth).
Assuming inflation is always bad. — Correct: Low inflation (2–3%) is healthy; high inflation (>8%) erodes savings; deflation traps economies.
Believing central banks can fix everything instantly. — Correct: Monetary policy takes 12–18 months to work through the economy; results are uncertain.
