Dynamic AD-AS
Model

A dynamic aggregate demand and supply framework where inflation adjusts over time, combining a monetary policy rule with adaptive inflation expectations.

Compare

This model uses static comparative statics -- no genuine time axis exists.

Shock presets

Fiscal expansion

A positive demand shock shifts the DAD curve rightward, raising both output and inflation.

Oil price spike

An adverse supply shock shifts the DAS curve upward, raising inflation while lowering output.

Inflation expectations drift

Expected inflation rises above target, shifting DAS upward even without a real supply disturbance.

Controls

Diagram, readouts, and summary update with each change.
