In this policy brief, we describe the Neighborhood Stabilization Program, which the Department of Housing and Urban Development first authorized in 2008, and the application of the program in Boston. After providing the background, definitions, and implementation context of the program, we proceed to describe the Boston case. A research team at the Federal Reserve Bank of Boston conducted a multi-method study of the impact of the Boston NSP effort. We found that the program properties were slower to be rehabilitated than a comparison group of non-program properties and that the program had very little impact on the physical or social conditions of the block. We conclude by offering some policy implications.
