Textbook graphs are still images. But policy is a moving force. The goal of this lab is to manipulate policy directly and feel equilibrium shifting with your own hands.

1. IS-LM: Where Does Equilibrium Land When Policy Is Applied?

Move the fiscal and monetary policy sliders. Watch how equilibrium output (Y) and the interest rate (r) respond in real time.

통화 공급 (M)기본

균형 분석 (Equilibrium)

균형 소득 (Y*)84.6

균형 이자율 (r*)32.3%

Core insight: fiscal policy shifts the IS curve; monetary policy shifts the LM curve. The equilibrium point is always determined by the intersection of the two forces.

2. Extending to AD-AS: When the Equilibrium Becomes a Price Level

IS-LM is a short-run analysis. When the price level (P) changes, the equilibrium coordinates translate into the Aggregate Demand (AD) curve.

AD — 총수요

SRAS — 단기 총공급

LRAS — 장기 총공급

3. The Phillips Curve: The Tension Between Unemployment and Inflation

Policy can push growth higher — but it comes with trade-offs. The Phillips Curve is the most intuitive tool for visualizing that tension.

SRPC — 단기 필립스 곡선

LRPC — 장기 필립스 곡선 (u* 자연실업률)

4. The Rhythm of the Business Cycle

Policy always operates on top of a business cycle. Whether the economy is in expansion or contraction changes how effective the same policy will be.

Q. What is the most typical short-run effect of expansionary monetary policy? A. The LM curve shifts right (downward), the interest rate falls, and national output tends to increase.

Today’s goal is not answers — it’s intuition. Press the policy levers. Watch the graphs move. Let the sensation stay in your fingertips.
