PROJECT APPRAISAL AND PROJECT AID: A DECADE OF EXPERIENCE IN RURAL DEVELOPMENT
考察了非洲农村发展中的项目援助绩效，评估了社会成本效益分析的应用，认为项目仍有价值但需纳入更广泛的部门与机构援助计划，并建议成本效益分析应更灵活、关注外部经济环境。
The paper is concerned with rural development in Africa: it examines project aid performance and evaluates the use of social cost‐benefit analysis. The paper concludes that in the 1980s projects do still have a place but as part of a wider programme of assistance to sectors and institutions. Social cost‐benefit analysis, based on the key concept of opportunity cost and aimed at the efficient allocation of resources, remains highly relevant, but should be applied to a wider range of problems, should give more attention to the external economic context and should be more flexible when uncertainty is high.
