A COMPARISON OF INFORMATION STRUCTURES FOR A RIGID DECISION RULE CASE
修改了个体决策模型，以处理决策者使用刚性决策规则（如对交通灯的条件反应）的情况，讨论了概率性和确定性的信息结构，并提出了不同于布莱克威尔定理的排序。
The information economics model of individual decision assumes that decision makers are capable of instantly modifying their decision rules in response to signal changes from the information structure. Individuals, however, often tend to stick to rigid decision rules, particularly when they are trained to respond with conditioned reactions, such as to a traffic light. This article modifies the individual decision model for such cases. It discusses probabilistic information structures as well as the deterministic information function. It results in an ordering of information structures that differs from the ordering imposed by the Blackwell Theorem. When deterministic information functions are considered, an ordering that is finer than the prevailing one is proposed. Transformations between deterministic and probabilistic information functions and the relationship between the proposed model and the previous theory are also discussed.
