Replication code availability over time and across fields: Evidence from the German Socio‐Economic Panel
研究了基于德国社会经济面板（SOEP）的2500多篇同行评审文章中复制代码的可用性，发现仅6%的文章提供代码，但比例随时间显著上升，受技术进步、研究者倡议和期刊政策驱动。
Abstract Providing replication code is an inexpensive way to facilitate reproducibility. However, little is known about the extent of replication code provision. Therefore, we examine the availability of replication code for over 2500 peer‐reviewed articles based on the German Socio‐Economic Panel (SOEP), one of the most widely used datasets in economics and other social sciences. We find that only 6% of SOEP‐based studies have code available, but that this proportion has increased sharply over time. We provide evidence that the increase in code provision is driven by technological advances, individual researcher initiatives, and journal policies.
