Assess students' ability to design a comprehensive urban housing affordability policy that balances economic incentives, zoning reform, social equity, and political feasibility. Task: produce an integrated policy proposal for a hypothetical mid-sized city (state assumptions) that includes fiscal tools (tax incentives, subsidies, financing), land‑use and zoning reforms (density increases, inclusionary zoning, ADUs), tenant protections, targeted equity measures, an implementation timeline, stakeholder engagement and political strategy, metrics for evaluation, and mitigation of likely trade‑offs and unintended consequences; justify choices with evidence and projected outcomes.
