受约束与不受约束的理性注意力不集中

理性疏忽文献分为两个版本的模型：在一个，状态和信号的互信息是有界的硬约束，而在另一个，它出现在决策者的效用函数的添加剂项。由此产生的约束和无约束的最大化问题是密切相关的，但尽管如此，他们的解决方案在某些方面有所不同。特别是，运动的决策者的先验信念和效用函数导致相反的比较静态的结论。
The rational inattention literature is split between two versions of the model: in one, mutual information of states and signals are bounded by a hard constraint, while, in the other, it appears as an additive term in the decision maker’s utility function. The resulting constrained and unconstrained maximization problems are closely related, but, nevertheless, their solutions differ in certain aspects. In particular, movements in the decision maker’s prior belief and utility function lead to opposite comparative statics conclusions.
