Bibliographic record
Abstract
The commercial sale of herbicide resistant (HR) canola has raised questions about the benefits of this new technology for seed and chemical companies, farmers, consumers, and other players in the supply chain. In this paper, we argue that the pricing and adoption of HR canola in Canada can not be understood if producers are seen as being homogeneous. We develop a conceptual model of producer heterogeneity that represents the distribution of benefits among producers. In this context, some farmers benefit from the new technology leading to adoption, while others do not. Empirical evidence supports this argument. In addition, the new technology co-exists with the traditional technology. Key words: herbicide resistant canola; producer heterogeneity; benefits; new technology; biotechnology. Canola is one of the first genetically modified (GM) crops to reach the commercial market in Canada. The focus of genetic modification is the addition of herbicide resistance to canola pl ts. In 1998, after four years of production, herbicide-resistant (HR) canola comprised 44 percent of total canola production in Canada (see table 1). One source estimates that Canadian HR c nol production could reach as high as 70 percent of total production in 1999 (Plant Breeding Institute (PBI), 1998). Table 1.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
