A Preanalysis Plan to Replicate Sixty Economics Research Papers That Worked Half of the Time
按预分析计划尝试复制67篇宏观经济学论文，发现强制要求提供数据和代码的期刊论文复制成功率更高，最终成功复制了约一半的论文，并提出了改进经济学研究可复制性的建议。
We attempted to replicate 67 macroeconomic papers using author-provided data and code files by following a preanalysis plan. Excluding 6 papers that used confidential data, we obtained data and code replication files for 29 of 35 papers (83 percent) that were required to provide such files as a condition of publication, compared to 11 of 26 papers (42 percent) that were not required to provide such files. Also excluding the 2 papers that used software we did not possess, we replicated 29 of 59 papers (49 percent) with assistance from the authors. We conclude with recommendations on improving replication of economics research.
