Rational Choice Under an Imperfect Ability To Choose
研究个体因信息处理能力有限而无法直接比较所有可行方案时，如何通过逐步调整当前配置来接近更高效用，并分析这种不完美选择能力如何改变标准模型的实证和规范预测。
The authors consider an individual who lacks the information-processing capacity required for a direct comparison of all feasible allocations. Instead of finding at once a best allocation, the individual myopically adjusts his current allocation toward higher utility. The individual makes adjustment errors inversely proportional to his ability to choose. The authors compare the stationary state of this process with the standard model. They see how an imperfect ability to choose modifies both positive and normative predictions of the standard model and how the standard model can be obtained from the authors' more general one as the special case corresponding to perfect ability.
