Two independently-sourced bibliographic records agree that Peter Thompson's July 2006 FIU working paper, "How Much Did The Liberty Shipbuilders Forget?", and the article later published as Management Science 53(6):908–918 (June 2007) are the same paper by the same author. RePEc/IDEAS's record for the published article gives the author as "Peter Thompson (Department of Economics, Florida International University, Miami, Florida 33199)" and the suggested citation "Peter Thompson, 2007. 'How Much Did the Liberty Shipbuilders Forget?,' Management Science, INFORMS, vol. 53(6), pages 908-918, June" (DOI 10.1287/mnsc.1060.0678). Thompson's own faculty-site publication list independently gives the identical citation as numbered entry "[34] How Much Did the Liberty Shipbuilders Forget? Management Science, 53(6):908-918 (June 2007)." Both match the working paper's own title page and footnote ("* Department of Economics, Florida International University, Miami, FL 33199") exactly on title, author, and institutional affiliation.

This establishes only that the published article is the same paper by the same author under the same title — bibliographic identity, not textual identity. It does not confirm the body text (point estimates, quoted passages) is word-for-word unchanged between draft and print; see claim-thompson-2007-published-abstract-matches-working-paper-abstract-except-two-copyedits for the one level of textual comparison this vault could reach, and question-does-thompson-2007-published-version-match-the-working-paper-numbers for what remains open. The claim rests on this vault's now-recurring finding that the journal's own venue of record, pubsonline.informs.org, is unreachable by its tooling — a gap this note works around rather than closes.
