Web1 jan. 2024 · Fox and Tversky (1995) observe comparative ignorance: people are more ambiguity averse when they evaluate ambiguous and clear prospects jointly rather than in isolation.To accommodate such patterns, I relax the multiple priors model and allow subjective sets of priors to depend on partitions that are generated by feasible prospects. … WebThe alpha-maxmin model is a prominent example of preferences under Knightian uncertainty as it allows to distinguish ambiguity and ambiguity attitude. These preferences are dynamically inconsistent for nontrivial versions of alpha. In this paper, we derive a recursive, dynamically consistent version of the alpha-maxmin model.
