Abstract

fetched live from OpenAlex

In this paper, we study a Stackelberg game for insurance contracting. Specifically, we assume that the insurance buyer and seller hold generalized mean-variance preferences and the premium is determined by a generalized variance premium principle. Under mild conditions, we derive the Bowley solution, which consists of the optimal indemnity and pricing functions, for the Stackelberg game. We also compare the Bowley solution with the Pareto optimal solution and prove that the Bowley solution can never be Pareto optimal. This finding shows the inefficiency of Stackelberg games in insurance contracting, which echoes the existing results derived in other settings. We present two specific examples to further show the implications of our main results as well as the sensitivity of the Bowley and Pareto optimal solutions with respect to the model parameters.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
