Malthusian pressures: empirical evidence from a frontier economy
Bibliographic record
Abstract
In this paper, we study Malthusian pressures in a frontier economy. Using the empirical data on real prices and demographic variables from 1688 to 1860 for Quebec and Montreal, we test for the existence of Malthusian pressures. Bearing in mind the particularities of frontier economies and the development of the Canadian economy, we conduct a Granger-causality analysis for the time-series of real wheat prices, birth and death rates with the help of VARs in order to identify positive and preventive checks. Using the Bai–Perron test we find a structural break in 1767 and divide the sample into pre- and post-conquest periods. We find that the positive checks were operating in the years prior to the conquest but that they faded during the nineteenth century. It follows that an increase in the wheat prices Granger-causes an increase in death rates in the pre-conquest period. Additional tests and a robustness check of the detrending methods are performed.

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.
