通过在塞内加尔达喀尔的随机对照试验，研究对社区组织提供群体激励能否促进其维护公共空间、改善清洁并减少洪水，结果证明干预有效。
Abstract What strategies can help communities to overcome the public goods problem in the maintenance of communal spaces and infrastructure in urban environments? This paper investigates whether an intervention targeted at Community-Based Organizations can motivate them to make increased contributions to the public good, thereby improving outcomes for the community as a whole. Using a randomized controlled trial conducted in Dakar, Senegal, the analysis tests the effectiveness of a program that provides incentives to community groups to encourage them to keep their neighborhoods clean, with the ultimate goal of reducing flooding. After one year, the intervention proved to be effective in engaging communities, improving cleanliness, and reducing flooding.
