Abstract

fetched live from OpenAlex

This study undertakes a comprehensive analysis of productivity growth in Canadian Prairie primary agriculture from 1940 to 2004. Total factor productivity (TFP) is measured using Törnqvist‐Theil indexing procedures for the Prairie provinces (Alberta, Manitoba, and Saskatchewan). During the 1940–2004 period, productivity growth in Prairie agriculture grew at a rate of 1.56% a year. This aggregate measure does not indicate the substantial variations in productivity growth that have occurred between crops and livestock, between the provinces, and over time: productivity growth in crops is considerably higher than productivity growth in livestock; Manitoba and Saskatchewan display consistently higher productivity growth than Alberta; and from 1980 to 2004 livestock productivity growth increased considerably in Manitoba and Saskatchewan. The productivity growth estimates are decomposed econometrically using a translog cost function to indicate the relative roles of technical change and scale effects. Productivity growth in crops has largely been the result of technical change while economies of scale have played a critical role in generating productivity growth in the livestock sector. La présente étude est une analyse approfondie de la croissance de la productivité du secteur de l’agriculture primaire dans les provinces des Prairies (Alberta, Manitoba et Saskatchewan), de 1940 à 2004. Nous avons mesuré la productivité totale des facteurs (PTF) à l’aide de l’indice Törnqvist‐Theil. De 1940 à 2004, la productivité de l’agriculture dans les provinces des Prairies a cru au rythme annuel de 1,56 p. 100. Cette mesure globale n’indique pas les variations substantielles de la croissance de la productivité entre le secteur des cultures et le secteur de l’élevage, entre les provinces, et au fil du temps. La croissance de la productivité dans le secteur des cultures a été considérablement plus élevée que celle observée dans le secteur de l’élevage. La croissance de la productivité au Manitoba et en Saskatchewan a été supérieure à celle observée en Alberta. De 1980 à 2004, la croissance de la productivité du secteur de l’élevage a enregistré une hausse considérable au Manitoba et en Saskatchewan. Nous avons décomposé la croissance de la productivité de façon économétrique à l’aide d’une fonction de coût de type translog afin de faire ressortir le rôle des changements technologiques et des économies d’échelle. Les changements technologiques ont joué un rôle important dans la croissance de la productivité du secteur des cultures, tandis que les économies d’échelle ont joué un rôle primordial dans la croissance de la productivité du secteur de l’élevage.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
