This research is funded by the European Union. Advocates of the CDD promise a long and varied list of benefits ranging from more efficient and cost effective provision of local public goods to the establishment of more inclusive institutions. The evidence on the impact of CDD is rather mixed. Greater community involvement seems to modestly improve resource sustainability and infrastructure quality, however, there is little evidence, that CDD transforms local decision making or empowers the poor in any enduring way. Our study contributes to this wider debate on the role of induced mobilization among marginalized groups such as women and the poor and gathers rigorous evidence regarding the impacts of CDD. The impact evaluation of the Sindh Union Council and Economic Strengthening Support (SUCCESS) Program is a multi-year randomized controlled trial designed to quantify the impact of the program on access to information and public services, and civic engagement; women empowerment; economic welfare; and social cohesion.
