Neighborhood upgrading effects of middle-income housing projects in New York City

Abstract In a sample of 50 New York City neighborhoods in which middle-income housing projects were built, assessed values increased by 9.89% per year while control areas increased only 4.64% annually. This upgrading effect is more pronounced in medium-quality neighborhoods than in either the best or the worst neighborhoods. Project size has apparently no effect on the impact of neighborhood upgrading, but project age seems to be positively related to neighborhood upgrading.
