Abstract

fetched live from OpenAlex

In reset years, many international uncertainties emerge, especially in trade policies. The US announced a higher tariff on imported commodities manufactured in China, Mexico, and Canada on 1 February 2025. The higher trade barrier gives a hint to explore how the uncertain trade policies affect the spot and future market under the case that most countries’ economies are connected tightly in the global market. This research estimates the impact of trade policy uncertainty on the stock index and stock index future. Fitting the VECM model during the influence persisting in the spot and future market and the whole period the research is conducted to test the return spillover effect between the CSI 300 index and the CSI 300 index future. After examining the return of spot and future, there is a spillover effect in the spot and future market, meanwhile, the price discovery of the future still works under the dynamic changes.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
