Abstract:
This document provides clarifications and guidance for researchers seeking to replicate the analyses in our paper. This is important as we identified some items in the published text and the code where additional clarity would be helpful. While none of these affect our substantive conclusions, we believe transparency requires that we document them here to facilitate future replication work, avoid confusion, and maintain the integrity of the scientific record. We also take this opportunity to note that updates and data quality issues in standard financial databases (discussed in Section B.1) may complicate replication efforts of our paper as well as others. Replication considerations specific to our paper follow beginning in section B.2.
