Assumptions (calibration overview)
- Effectiveness: Gains scale with stringency × coverage, enforcement, and (modestly) public investment; equity targeting slightly improves adoption/effectiveness in disadvantaged areas.
- Costs: Private compliance grows convexly & increases near 100% stringency/coverage; enforcement still causes sharp increases, but market tools are less swamped by high-E monitoring costs.
- B/C: Benefits = monetized reduction in violations; Costs = private out-of-pocket + city admin/enforcement + annualized grants + (if chosen) EJ program costs (targeting/rebates). Uncertainty: ±35% on benefits; ±20% on costs.
