DescriptionUrban municipal governments often face challenges when redeveloping their distressed centers. In 2000, the City Council of Philadelphia passed a series of bills modifying its existing residential tax abatement policies to expand their eligibility and to make them last for ten years. The timing of the passage of these bills also corresponded with Mayor John Street’s Neighborhood Transformation Initiative (NTI), which aimed to prepare land for redevelopment. The combination of the revised abatement policies and NTI created a series of competing interests for politicians, business owners, and community organizations. Utilizing a methodological design consisting a historical critical analysis based on urban regime theory, GIS, and regression analysis, this dissertation profiles the formulation, implementation, and impact of Philadelphia’s tax abatement policies from 2000 to 2010. It also proposes a mechanism by which government policies can facilitate or accelerate gentrification. Results show support for a relationship between the incidence of tax abatements and gentrification.
