Alternative Measures for Modeling Risk and Expected Utility Theory (Risk Adjustment, Measurement and Attitude)
Bibliographic record
Abstract
In this paper, we propose alternative measures for modeling risk to be used in Expected Return (ER) calculations instead of “Utility” of Expected Utility Theory (EUT). These new measures are based on the idea that: First, there is a need to make a Risk-Adjustment to make the risky-alternative comparable with the risk-free alternative. Second, the new measures can be more in congruence with actual risk attitude existing in the market. This is possible by making the Risk-Measurement to be included in the probability function and the expected return to be based on the market portfolio on the Capital Market Line (CML) tangent to the Markowitz Bullet as defined in CAPM of finance theory. Finaly, these new measures may also make it possible to include Risk-Attitude in the “Probability” or “Returns” functions and there may no longer be need for a “Utility” function. The two measures introduced in the paper can be used with certain advantages as a substitute for expected utility theory of economics, game theory and decision theory in predicting choice behavior under risk, and in a more correct financial derivatives pricing using binomial models of finance.

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.
