公平地实现成本效益：通过坦桑尼亚的Camfed计划提高边缘化女孩的学习 Summary This policy paper provides a cost-effectiveness analysis of Camfed's programme in Tanzania. Camfed's programme adopts a multidimensional approach that is aimed at reaching marginalised girls at risk of dropping out from secondary schools by using interventions that are aimed at both increasing their chances of staying in school and learning. This paper highlights three issues that are relevant for these types of equity-led interventions： （i） Higher cost provision is necessary to reach the most marginalised. Programmes focused on the most marginalised are often more costly. Judging them based purely on cost may not result in investment in programmes that reach those who need the most support. （i） The higher cost necessary to accomplish equitable outcomes could， however， still result in higher overall cost-effectiveness. Raising learning of interventions targeted at the most marginalised could be of a magnitude such that， despite higher costs， they are still of reasonable overall effectiveness. （ii） But can these programmes be sustained in the long run? Are they replicable and scalable in other contexts? There are important considerations that need examining particularly as these programmes potentially have higher costs. Using data from a quasi-experimental design linked with detailed programme financial information， this paper undertakes a cost-effectiveness analysis to measure Camfed's programme costs in relation to the programme's estimated impact. Camfed's programme shows that， while it may be more costly to reach the most marginalised， the impact is impressive. 【更多详情，请下载：公平地实现成本效益：通过坦桑尼亚的Camfed计划提高边缘化女孩的学习】
