Abstract

fetched live from OpenAlex

Abstract We study the effects of international trade on the oligopsony power of firms in input markets. We build a theoretical model of international trade in which firms are oligopolists in the market for final goods and oligopsonists in the market for inputs. Consistent with evidence from the literature, firms' markups over unit costs rise with the level of oligopsony power and of oligopoly power. While trade liberalization decreases market power in one market, it has the opposite effect in the other. In particular, international competition between oligopolists in final goods markets causes oligopsony power to increase and oligopoly power to decline. In a simulation, we show that the increase in oligopsony power can more than offset the reduction in oligopoly power, resulting in a net increase in markups over unit costs.

Not 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.
