Bipolar behavior of submodular, law-invariant capacities

Amarante, Massimiliano - In: Statistics & Risk Modeling 38 (2022) 3-4, pp. 65-70

Abstract In the case of a submodular, law-invariant capacity, we provide an entirely elementary proof of a result of Marinacci [M. Marinacci, Upper probabilities and additivity, Sankhyā Ser. A 61 1999, no. 3, 358–361]. As a corollary, we also show that the anticore of a continuous submodular,...

"Agreeing to Disagree" Type Results under Ambiguity

Lefort, Jean-Philippe; Dominiak, Adam - Université Paris-Dauphine (Paris IX) - 2011

Nehring-unambiguous events. The results obtained allow to attribute the existence of a speculative trade to the presence of …-but-not-necessarily-additive prior beliefs represented by capacities. It is shown that, if each agent's information partition is made up of unambiguous … events in the sense of Nehring (1999, Mat. Soc. Sci. 38, 197-213), then it is impossible that the agents disagree on their …

Even a small departure from that notion of unambiguous events creates profitable trade opportunities due to …

Probabilistic Sophistication, Second Order Stochastic Dominance, and Uncertainty Aversion

Cerreia-Vioglio, Simone; Maccheroni, Fabio; Marinacci, … - Collegio Carlo Alberto, Università degli Studi di Torino - 2010

We study the interplay of probabilistic sophistication, second order stochastic dominance, and uncertainty aversion, three fundamental notions in choice under uncertainty. In particular, our main result, Theorem 2, characterizes uncertainty averse preferences that satisfy second order stochastic...
