Judgment aggregation without full rationality
Several recent results on the aggregation of judgments over logically connected propositions show that, under certain conditions, dictatorships are the only propositionwise aggregation functions generating fully rational (i.e., complete and consistent) collective judgments. A frequently mentioned route to avoid dictatorships is to allow incomplete collective judgments. We show that this route d...
متن کاملJudgment aggregation without full rationality: a summary
Several recent results on the aggregation of judgments over logically connected propositions show that, under certain conditions, dictatorships are the only independent (i.e., propositionwise) aggregation rules generating fully rational (i.e., complete and consistent) collective judgments. A frequently mentioned route to avoid dictatorships is to allow incomplete collective judgments. We show t...
متن کاملAmbiguity without a State Space
Many decisions involve both imprecise probabilities and intractable states of the world. Objective expected utility assumes unambiguous probabilities; subjective expected utility assumes a completely specified state space. This paper analyzes a third domain of preference: sets of consequential lotteries. Using this domain, we develop a theory of Knightian ambiguity without explicitly invoking a...
متن کاملStochastic Games on a Product State Space
Stochastic games and product-games. An n-player stochastic game is given by (1) a set of players N = 1 n , (2) a nonempty and finite set of states S, (3) for each state s ∈ S, a nonempty and finite set of actions As for each player i, (4) for each state s ∈ S and each joint action as ∈×i∈N As , a payoff r i s as ∈ to each player i, (5) for each state s ∈ S and each joint action as ∈×i∈N As , a ...
متن کاملAmbiguous Bayesian Games
Bayesian games can handle the incomplete information about players’ types. However, in real life, the information could be not only incomplete but also ambiguous for lack of sufficient evidence, i.e., a player cannot have a precise probability about each type of the other players. To address this issue, this paper firstly extends the Bayesian games to ambiguous Bayesian games. Then, we introduc...
