Run the Model Yourself
BigSim simulates a scaled US economy with individual households and firms making their own decisions. Watch feedback loops, policy responses, and economic dynamics unfold in real time.
For model assumptions and scenario design, see Methodology.
Run a Scaled-Down Version
In Your Browser
Configure household and firm scale directly, then run either a single simulation or a tiered health batch. Watch feedback loops unfold in real time.

💡 How to Read Results
Compare scenarios by holding seed and run length constant, then changing one policy block at a time. Track unemployment, GDP path, inflation, debt dynamics, and firm survival together instead of relying on a single metric.
Scenario design guideSimulation Health
Tiered baseline evaluation with per-seed status and batch gates.
Selected run tier
1,000 households • 46 firms • 1 seed • 40 years • warmup 20 years
Batch gates: target pass fraction ≥ 80%, acceptable outliers ≤ 1, hard-limit violations = 0.
No simulation health run yet.
Pick a tier and run the health check to see seed-level gating.
