American Economic Review
In 2004, the AER began generally requiring data used in empirical papers. Specifically, "Submitters should be aware that the Editors now routinely require, as a condition of publication, that authors of papers including empirical results (including simulations) provide to this office, in electronic form, data and code sufficient to permit replication. Exceptions, for proprietary data for example, must be approved by the Editor in advance of the review process."
