Abstract

fetched live from OpenAlex

This project investigates empirically whether retailer size influences their direct importing activities.Twenty three Canadian retail sectors are analyzed,classified by types of commodities for the year 2002. Two aspects of retailer size are considered, average size and size dispersion of retail establishments in a retail sector. Other explanatory factors include: the share of purchases of imports by wholesalers selling the same product category of each retailer type; Canadian production of the commodities sold in each retail sector, as a fraction of total Canadian production of the year; and three importing sources (the US and Mexico, EU and Japan and Low Cost Asian countries). Only non-highly correlated independent variables are included in each estimation. The best estimation suggests that there is significant negative correlation between average size of retail establishments and their direct import activities; and there is negative link between size dispersion of retail establishments and their direct import activities.

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.
