Abstract

fetched live from OpenAlex

Starting in the 2013-14 crop year, a lack of export capacity resulted in substantial increases in the spread between farm and port FOB prices in western Canada. This created a very difficult situation for the farming community. We calculate that this situation reduced grain farmers’ income over the 2013-14 and 2014-15 crop years by approximately C$6.7 billion. Clearly, the grain handling and transportation system has problems and capacity to move grain is one of them. To evaluate the need for grain export capacity expansion, we forecast future grain production using a rational expectations model to estimate future export spreads and subsequent rents. We find that without capacity improvements, the expected cost of limited grain export capacity could exceed C$5.6 billion over the next decade. Capacity improvements on the order of a 25% increase will likely mitigate this issue in the future.

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.
