Slum Clearance and Urban Renewal in the United States
研究美国联邦城市更新项目对地方经济的影响，发现该项目显著提升了收入、房产价值和人口，且效果并非由人口结构变化驱动。
We study the local effects of a federal program that helped cities clear areas for redevelopment, rehabilitate structures, complete city plans, and enforce building codes. We use an instrumental variable strategy to estimate the program's effects on city-level measures of income, property values, employment and poverty rates, and population. The estimated effects on income, property values, and population are positive and economically significant. They are not driven by changes in demographic composition. Estimated effects on poverty reduction and employment are positive but imprecise. The results are consistent with a model in which local productivity is enhanced.
