Gentrification: Perspectives of economists and planners

Gentrification touches on issues at the core of the fields of urban economics, planning, and geography. This article aims to look across disciplines and review the literature on gentrification. It begins by discussing how gentrification is defined and understood by different researchers and assessing its importance or prevalence over time. It then contrasts the theoretical approaches used to explain the causes of gentrification in different fields. It focuses on different models used by economists on the one hand and planners, on the other. The economic models of neighborhood change focus more on market forces and individual choices, while planning and geography models emphasize class and politics. Following this, the article reviews the literature on the consequences of gentrification, summarizing the empirical evidence. Finally, it highlights what is still unknown about gentrification, in terms of the process and drivers, its consequences, and the role it might play in future urban revitalization.
