一种辩护模式

摘要：

我认为决策受到道德、理性或其他美德的约束。决策者（DM）对结果有一个真正的偏好，但觉得必须在他认为“合理的”偏好中排名第一的结果中做出选择。“这个模型结合了关于分配偏好、慈善捐赠、偏见/歧视和腐败/贿赂的广泛的经验工作。我提供了模型的行为特征。我还表明，设置的理由可以确定从选择行为时，真正的偏好是已知的，选择行为大大限制了真正的偏好和理由时，都是未知的。我认为，可解释性模型代表了对现有模型的合理化，因为它的结构可能的“理据”提高了易处理性，解释和识别的进步。

英文摘要：

I consider decision-making constrained by considerations of morality, rationality, or other virtues. The decision maker (DM) has a true preference over outcomes, but feels compelled to choose among outcomes that are top-ranked by some preference that he considers "justifiable." This model unites a broad class of empirical work on distributional preferences, charitable donations, prejudice/discrimination, and corruption/bribery. I provide a behavioral characterization of the model. I also show that the set of justifications can be identified from choice behavior when the true preference is known, and that choice behavior substantially restricts both the true preference and justifications when neither is known. I argue that the justifiability model represents an advancement over existing models of rationalization because the structure it places on possible "rationales" improves tractability, interpretation and identification.
