Theory-Based Models

IS-LM Model

Simultaneous equilibrium in the goods market and money market, tracing how spending and liquidity conditions jointly pin down output and the interest rate.

Theory-Based Models

Overview

Route section

A stripped-down short-run framework for tracing how fiscal demand, liquidity preference, and money-market conditions meet at one output-interest combination.

Core question

How do demand and liquidity conditions settle at one macro equilibrium?

Start with this visual summary, then move to explore for parameter control and compare for side-by-side scenarios.

Variables

YYY

Output

Real output in short-run equilibrium.

iii

Interest rate

The interest rate that clears the money market.

ISISIS

Goods-market schedule

Downward-sloping demand equilibrium curve.

LMLMLM

Money-market schedule

Upward-sloping liquidity-money curve.

Keep this panel as the fast first pass. Use explore for calibration workflow and compare for alternate scenarios.

Assumptions

Prices are fixed in the short run.

The model is about real demand and money-market equilibrium, not inflation adjustment.

The baseline setting is a closed economy.

Open-economy capital flows are handled separately in Mundell-Fleming.

IS and LM are rendered as linear schedules.

The route keeps the geometry readable and the comparative statics transparent.

Parameters

AAA

Autonomous spending

IS curve

Demand that does not depend on current income.

bbb

Interest sensitivity

IS curve

How sharply spending falls as the interest rate rises.

m0m_0m0​

Liquidity intercept

LM curve

Baseline rate implied by money-market conditions.

m1m_1m1​

Liquidity slope

LM curve

How strongly money demand pushes rates up as output rises.

Shock presets

Fiscal expansion

Higher autonomous spending shifts IS to the right.

Liquidity tightening

A tighter money market shifts LM upward.
