Abstract
This paper revisits the gains from trade under imperfect competition by explicitly modeling strategic competition and entry. The papers highlights a welfare cost of imperfect competition, due to inefficiently high entry. Through increasing competition, international trade lowers price–cost markups and reduces excessive entry. This adds on a “competitive” channel for gains from trade to the well‐known “product diversity” channel from previous literature. Both channels will increase the return to investment and raise the steady‐state capital stock. An alternative case is possible, however, where there is inefficiently low entry. In that case, trade tends to be “anticompetitive,” raising price–cost markups and encouraging increased entry.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
