🧪 Economics Macroeconomic Analysis Simulation

This simulation lets you shock a simplified economy with fiscal spending, money-supply growth, or a cost-push supply shock, then watch how real GDP and the price level find a new short-run equilibrium and — as expectations adapt period by period — drift back toward potential output. The Aggregate Demand and Short-Run Aggregate Supply lines are rendered at the front of a 3D tunnel; the equilibrium's history recedes into the screen along a time axis so the self-correcting business-cycle dynamic is visible as a single continuous path curving back toward the potential-output wall, rather than as a static textbook diagram.
