Given the growth of interest and activity in experimental economics and the considerable increase in the number of submissions, some reflection on submission guidelines may be in order.

Unlike most other manuscripts received, detailed information about experimental procedures is relevant to the decision of whether or not to publish an experimental manuscript. Such information is also very valuable to scholars who subsequently work on related research. Therefore, the author(s) should include with their submitted manuscript an appendix which adequately explains the details of the experimental procedures. For example, a copy of the instructions that were handed out or read aloud to the subjects should be included. Other materials, such as sample subject record sheets, are also often helpful for the referee. If experiments are conducted through a computer network, this may be more difficult to do, since instructions are sometimes given by a sequence of computer screens and “tests.” If instructions were presented by computer, then a summary of the computer-aided learning algorithm, and, if possible, hard copies of the computer screens, should be included. If there are too many screens, this may not be practical. In some cases, a reasonable substitute might be for the author(s) to submit a detailed written description of the instructional procedures for the computer-conducted experiments. (Authors are not required to provide software to other researchers, but this is encouraged.) Enough information should be provided to permit valid replication.
