An exchange of email messages between Warfield and Zhichang Zhu, the book review editor for Systems Research journal. Warfield, as part of his ongoing Economics Research project, is considering a tandem submission, in which he might publish in the same issue a book review and an accompanying article related to the book's theme. This document was part of Warfield's collection for his Economics Research studies. He had placed a copy of it in his Economics Research Note-binder No. 6 and listed it in his Index of economics study papers.
