Abstract

fetched live from OpenAlex

A hedonic pricing model is estimated for Alberta farmland values using pooled cross-sectional data spanning the years 2000-2011. Explanatory variables are chosen based on relevant theoretical and empirical considerations. In addition to conventional variables such as agricultural returns, distance to an urban centre, change in population density, soil quality, presence of improvements, and irrigation, supplementary variables are included to examine the impacts of farmland conversion (to developed uses) and fragmentation on farmland prices. Results are generally consistent with expectations. For example, higher soil quality is associated with higher farmland values. Furthermore, fragmentation and conversion appear to have some positive influence on farmland values in Alberta. Information concerning the influence of fragmentation and conversion on farmland values and the implications for future farmland conversion and preservation is of value to policymakers in making decisions regarding land use frameworks and other land use related policies.

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.
