Test ability to apply comparative policy analysis to evaluate the effectiveness of inclusionary zoning (IZ) on affordable housing supply in mid-sized U.S. cities: define case-selection criteria and timeframe; choose quantitative and qualitative outcome indicators (units produced, affordability depth, production rates, displacement effects, private-sector responses); propose comparative methods (difference‑in‑differences, synthetic control, matching, process tracing); identify confounders and data sources; interpret hypothetical findings and offer policy recommendations.
