I just got an e-mail from someone I had sent it to asking "Is it OK to share your member?" I think the person must have been simultaneously thinking "memo" and "paper", but I'm not sure. In any case, I wrote back that it was okay to share my paper. Remarkably, perhaps, I was able to restrain myself from adding that it was definitely not OK to share my member with anyone.
Anyway, I received more information on the Great Leap Forward by economics in its expectations regarding the information researchers will provide at the time of publication. A key moment was apparently a 2003 paper by McCullough and Vinod that included an effort to replicate the five papers that used nonlinear models in a single 1999 issue of AER. Authors of one of the papers cooperated with the investigators' queries. Of the other four, McCullough and Vinod report:
Two authors provided neither data nor code: in one case the author said he had already lost all the files; in other case, the author initially said it would be "next semester" before he would have time to honor our request, after which he ceased replying to our phone calls, e-mails, and letters. A third author, after several months and numerous requests, finally supplied us with six diskettes containing over 400 files--and no README file... A fourth author provided us with numerous datafiles that would not run with his code. We exchanged several e-mails with the author as we attempted to ascertain how to use the data with the code. Initially, the author responded promptly, but soon the amount of time between our question and his response grew. Finally, the author informed us that we were taking too much of his time.
