Abstract

fetched live from OpenAlex

Demand and supply for commercial air travel are not independent. A more popular route allows airlines to increase the number of non-stop flights, which further shifts demand. Forecasting future air travel demand on inter-city routes requires distinguishing endogenous and exogenous determinants of service quality. The paper presents successful econometric estimates of gravitybased models of passenger numbers with subsidiary models of (a) price (controlling for airline competition), (b) provision of non-stop services, and (c) frequency of daily flights, for two markets: cross-border flights between Canada and the USA, and domestic air travel within New Zealand.

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.

Full frame distilled prediction

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.
