Assessing the Rate of Replication in Economics
研究了2010年《美国经济评论》中70篇实证论文的复制情况，发现29%有部分复制，60%有复制、稳健性检验或扩展，但作者对现有复制数量存在不确定性。
We assess the rate of replication for empirical papers in the 2010 American Economic Review. Across 70 empirical papers, we find that 29 percent have 1 or more citation that partially replicates the original result. While only a minority of papers has a published replication, a majority (60 percent) have either a replication, robustness test, or an extension. Surveying authors within the literature, we find substantial uncertainty over the number of extant replications.
