Replication in Labor Economics: Evidence from Data and What It Suggests
研究了1990年代初劳动经济学中被引最多的论文，发现直接复制很少，但通过不同时期和经济体的数据验证了核心思想，表明现有学术市场已能有效复制非实验室应用研究。
Examining the most heavily cited publications in labor economics from the early 1990s, I show that few of over 3,000 articles, citing them directly, replicates them. They are replicated more frequently using data from other time periods and economies, so that the validity of their central ideas has typically been verified. This pattern of scholarship suggests, beyond the currently required depositing of data and code upon publication, that there is little need for formal mechanisms for replication. The market for scholarship already produces replications of non-laboratory applied research.
