Abstract
The reasons customers substitute, are well understood from an economic perspective. However, its exact impact on retailer's inventory and profit is not, when customers substitute as a result of a shortage. Shortage of one product may lead to demand spillover, due to substitution, resulting in shortages for the second product. We call this inventory cannibalisation. This is a store level, retailer observed phenomenon that is a direct result of customers' willingness to switch between substitutes due to stockout of one product. Many retailers are experiencing stockouts related to substitution, resulting in a significant loss of revenue. We model a retailer's selling two substitutes, facing price-sensitive stochastic demand. Our model incorporates cannibalisation explicitly and generalises the existing literature on inventory substitution. We perform analytical and numerical analysis to study the impact of stockout-based substitution and the related inventory cannibalisation on retailer's decisions. We find that the impact of cannibalisation is felt most acutely by the retailer for products with low degree of substitution.

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 it
