(A,f): Choice with Frames1
构建了一个模型，用于分析框架效应下的选择行为。扩展选择函数为每对（选项集，框架）指定一个被选元素，框架包含不影响理性评估但影响选择的可观察信息。研究扩展选择函数与经典选择对应模型的关系，并识别存在传递或传递且完备二元关系的条件。
We develop a framework for modelling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f) where A is a set of alternatives, and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of the alternatives, but nonetheless affects choice. We relate the new framework to the classical model of choice correspondence. Conditions are identified under which there exists either a transitive or a transitive and complete binary relation R such that an alternative x is chosen in some (A, f) iff x is R-maximal in the set A. We then demonstrate that the framework of choice correspondence misses information, which is essential to economic modelling, and which is incorporated in the extended choice function.
