Three ‘Rs’ of Econometrics: Repetition, Reproduction and Replication
指出标准应用计量方法缺乏科学所需的独立验证（复制），强调复制对评估量化研究可信度的重要性，尤其对英国国际发展部倡导的循证政策制定有启示。
Development economics has become increasingly quantified in recent years, reflecting the aspirations of economists to practise hard science. We argue that standard applied econometric methodology lacks one key feature of the claim of science to be scientific, namely replication as part of independent confirmation of findings. Replication plays a large role in understanding the confidence we can place in the quantitative studies on which much policy advice rests, which is particularly salient in a UK context given the emphasis placed on evidence-based policy-making by the UK Department for International Development.
