Large-scale affordable housing construction and public goods provision: evidence from Iran
研究了伊朗最大的保障性住房项目（Mehr项目）对周边房产价值的影响，发现房价下降11%，但在学校等公共设施同步扩张的区域，负面效应消失。
Abstract Affordable housing projects may affect neighboring property values. Negative spillovers are more likely in developing countries because governments may fail to provide complementary infrastructures such as schools. We study one of the world’s largest affordable housing projects, the Mehr housing project in Iran, which facilitated the construction of 2 million affordable apartments. Using the universe of house transactions in nineteen large cities, we employ a difference-in-differences methodology to estimate the causal impact of Mehr on neighboring properties. Results show nearby housing prices fall by 11%. This negative effect fades away in neighborhoods that saw a proportionate expansion of schools.
