What changes when
one policy changes?

Run a deterministic, matched-seed experiment. Both cities begin with the same mixed-economy policies; only the selected policy lever changes. Each experiment is independent of your saved game.

1. Choose an experiment

The lesson changes only one economic parameter.

Ready to run.

2. Observe the results

Control = original mixed preset; Treatment = one revised policy parameter. A positive change is not necessarily a benefit; inspect debt, affordability and service quality together.

Choose a lesson, then run it to see modeled changes.

Reproducibility and modeling caveats
No model run yet.

3. Discuss the tradeoffs

Where did economic conditions improve? Which indicators worsened? Can a real policy claim be justified from this synthetic simulation alone?

Important: The model was not experimentally validated on real cities. The differences reflect its programmed assumptions, not causal estimates or recommendations for public policy.
