Obvious representations
在标准假设下，尊重显式支配刻画了显式表示的存在性。通过对表示施加不同条件，可得到多种偏好模型，如一般单调、不变双可分离、Choquet等，并便于模型比较和参数识别。
Under standard assumptions, the respect of obvious dominance characterizes the existence of what we call obvious representations . We show that various conditions imposed directly on these representations pin down general monotonic, invariant bi-separable, general Choquet, convex Choquet, neo-additive Choquet, and subjective expected utility preferences. Among other insights, the alternative axiomatizations which we thus provide facilitate comparisons between models, as well as the identification of their parameters. Co-minimal and co-maximal acts — a natural generalization of co-monotonic acts, the relevance of which is further confirmed by our results — play a significant role in our analysis. Our results further testify of the fundamental importance of obvious dominance, and they offer a proof of concept that obvious representations constitute a fruitful format for axiomatic investigations.
