Abstract

fetched live from OpenAlex

Abstract This study assesses agricultural economics literature on farmland prices and key determinants of these prices. The first section of the paper uses a basic capitalization model to organize a review of the literature and data. We then provide a focused assessment of five streams of literature examining farmland prices: (1) boom‐bust; (2) the capitalization effect of government agricultural subsidies on farmland prices; (3) agricultural zoning; (4) climate change; and (5) prohibitions against non‐local buyers of farmland. Our review highlights challenges to ongoing efforts to model changing farmland prices, the modern emphasis on econometric identification, important variation in the magnitude of estimated relationships across the literature, and the opportunity to expand research in Canada.

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.
