Abstract

fetched live from OpenAlex

A model is provided whereby a monopolist firm chooses to price its product at zero. This outcome is shown to be driven by the assumption of 'free disposal' alongside selection markets (where prices impact on a firm's costs). Free disposal creates a mass point of consumers whose utility from the product is zero. When costs are negative, the paper shows that a zero price equilibrium can emerge. The paper shows that this outcome can be socially optimal and that, while a move from monopoly to competition can result in a negative price equilibrium, this can be welfare reducing. The conclusion is that zero can be a 'special zone' with respect to policy analysis such as in antitrust.

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.
