All of the top general-purpose economics journals have a data and code-sharing policy. As of this writing, the Journal of Finance has a code-sharing policy, the Journal of Financial Economics (JFE) requires authors to share code if the results are challenged, and the Review of Financial Studies (RFS) is currently developing a policy. Replication is essential to any scientific endeavor, so why has the area of financial economics lagged behind?
