Macro-development economists need to recognize the advantages of the experimental approach and adopt the policy mindset of enthusiasts of randomized evaluation. Micro-development economists need to recognize that one can learn from diverse types of evidence, and that, while randomized evaluations are tremendously useful, the utility of their results is often restricted by the narrow scope of their application.
发展政策领域可以也应该重新统一，以共享诊断式具体分析方法为中心。宏观发展经济学家需要认识到实验方法的优势，接受热衷于随机化评估的政策方法。微观发展经济学家需要认识到，你可以从各种经验中学习，尽管随机化评估非常有用，但其效果通常局限于狭窄的适用范围。
