We also printed all of AMJ’s “From the Editors”
sections (originally called “Editorial Comments”)
and “Information for Contributors” sections (originally
called “Suggestions to Authors”). We noted
cases in which these sections articulated the journal’s
policy on theoretical contributions. Some of
the cases concerned a change or adjustment to the
policy, whereas others were efforts to clarify or
deepen potential authors’ understanding of the existing
policy. Appendix A summarizes the most
significant changes in AMJ’s “Information for Contributors”
over the past five decades. The Appendix
includes the editor who originally crafted each
statement, the years in which the statement was in
effect, and an excerpt relevant to the issue of making
a theoretical contribution.
