Overview

What is Macroeconomics?

The most common definition: Macroeconomics is the study of the behaviour of a national or regional economy as a whole.

But as Blanchard said, "The best way to answer is not to give you a formal definition, but rather to take you on an economic tour of the world."

For me, "A model can describe the world" is an exciting thing. This website records the macroeconomic tools and models I have learned, forming a structured knowledge network from introductory concepts to advanced techniques.

Growth Theory Solow, RCK, OLG, endogenous growth, growth accounting 4. Short-Run Fluctuations IS-LM, AS-AD, DAS-DAD, Phillips Curve, expectations 5. Monetary Economics New Keynesian, sticky prices, Taylor rule, rules vs. discretion 6. Open Economy Exchange rates, Mundell-Fleming, interest parity, twin deficits 7. Labor Market DMP search & matching, Beveridge curve, Phillips Curve foundations 8. Financial Frictions Financial amplification, collateral constraints, the Great Recession 9.

Learning Pathway

Concepts→ Micro Foundations→ Growth→ Short Run→ Monetary

This forms the core sequence: start with basic concepts, build micro foundations for household/firm behavior, understand long-run growth, then short-run fluctuations, and finally how monetary policy interacts with the real economy.

Open→ Labor→ Financial→ Methods

The specialized modules extend the core: open economy considerations, labor market frictions, financial amplification mechanisms, and the mathematical toolkit.
