Cambridge Core permits the use of electronic supplementary material to accompany papers published in Econometric Theory. This improves the conciseness and readability of ET articles.
As instructed by the Editor and/or CoEditors, authors may divert certain content to online supplementary material, such as long details of mathematical derivations, supporting lemmas, tables, figures and other graphics, and then send it in at the same time as the final version of their manuscript to ET for online availability. A separate copyright form for the supplementary material is not required.
This separate file should be clearly labeled as supplementary material and headed up "Supplementary Material on "title of paper" ". ONLY critical supplementary material should be included, as directed by the Editor/CoEditor. Authors can always refer readers to a preprint if they want to draw attention
to a lot of extra material.
The peer review process applies to supplementary material so that material included in a supplement to a paper must have been reviewed before acceptance. In practice, this will usually mean the original paper is carefully reviewed and then a decision is made by the Co-Editor or Editor to put some of the material into a supplement, which can then be overviewed for its content. Therefore, authors must put only reviewed material into a supplement and not to use it as an opportunity to introduce new, unseen material.
In contrast to the published articles--for which ET provides an extraordinary level of production service—online supplementary material will not be copyedited or typeset. That being the case, authors must assume responsibility for accuracy.
Online there will be an appropriate link next to the article for readers to click on and access the supplementary material.
Authors should ensure that they mention within their article that supplementary material is available on Cambridge Core. Citation of supplementary material must be made within the text of the article in a reference of the following type:
"The details of xxxxxx are provided online at Cambridge Core in supplementary material to this article. Readers may refer to the supplementary material associated with this article, available at Cambridge Core (www.cambridge.org/core/journals/econometric-theory)."
