The ‘Double Movements’ of Neighbourhood Change: Gentrification and Public Policy in Harlem and Prenzlauer Berg

This article explores the interrelation of gentrification and public policies in the neighbourhoods of Prenzlauer Berg (Berlin) and Harlem (New York City). It draws on Karl Polanyi’s concept of a ‘double movement’ and argues that gentrification is fundamentally a political process. Thus, while demise in the face of market forces, or even an active support of gentrification, is clearly visible in both neighbourhoods, the relation between public policies and gentrification is also highly unstable and contradictory. The cases studied highlight that the resources to push or prevent gentrification are contingent; they are not built into the essence of urban development.
