We are providing this statement to make clear the relationship between two articles (Nores et al. 2005 and Belfield et al. 2006) in a way that was not heretofore evident to the editors or readers at the time of the original publications. These two articles published 15 years ago set forth interrelated issues from the same study for two different audiences. It came to our attention that recently a question was raised about whether they are duplicative. We realize in retrospect that these two articles are close enough in substance that we should have advised the JHR and EEPA editors of these simultaneous sub- missions so that they, and not we, could judge whether they were sufficiently distinct to warrant publication in the two outlets. Since we, as well as our fields and journals, take seriously dual publication or piecemealing, this statement aims to help ameliorate such concerns.
