<b>Invited Commentary</b>—Marketing Structural Models: “Keep It Real”
Bibliographic record
Abstract
In their article, “Structural Modeling in Marketing: Review and Assessment,” Chintagunta, Erdem, Rossi, and Wedel (2006) provide a comprehensive survey of the contributions to the empirical marketing literature made by researchers using structural econometric modeling. More importantly, their review poses the question of whether structural methods should become more prominent in marketing research. Addressing that question requires a careful consideration of the potential gains of employing structure in this context, as well as the compromises necessary for implementation. Instead of specifically referencing many of the interesting papers cited by the authors, I will focus my comment on evaluating the value of structural approaches in marketing in more general terms.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
