On Hurwicz preferences in psychological games

De Marco, Guiseppe; Romaniello, Maria; Roviello, Alba - In: Games 15 (2024) 4, pp. 1-26

extend the analysis by taking into account α-max-min preferences in which decisions are evaluated by a convex combination of … the worst-case (with weight α) and the best-case (with weight 1 − α) scenarios. We define the α-max-min psychological Nash … equilibrium; an illustrative example shows that the set of equilibria is affected by the parameter α and the larger the ambiguity …
