激励驱动的注意力不足
- 研究问题
- 专业预测者是否根据信息处理的成本与收益选择注意力，预测更新的频率和幅度能否提供理性注意力机制的经验证据？
- 方法与思路
- 作者利用自主选择更新日期的通胀预测数据、预测竞赛和官方数据发布，结构估计更新决策与更新幅度均内生的模型。
- 材料陈述的贡献
- 摘要称信息处理努力会响应激励变化；模型反事实显示，当竞赛日期与信息发布同步时，预测准确度达到最大。
- 阅读关注点
- 应核对注意力参数如何由更新行为识别、竞赛与数据发布的作用、模型拟合，以及日期同步反事实依赖的结构假设。
- 阅读边界
- 仅依据所给出版社摘要，无法判断激励变化的识别条件、参数不确定性和反事实外推有效性；准确度结论限于所述模型与场景。
原文摘要
“Rational inattention” is becoming increasingly prominent in economic modeling, but there is little empirical evidence for its central premise-that the choice of attention results from a cost-benefit optimization. Observational data typically do not allow researchers to infer attention choices from observables. We fill this gap in the literature by exploiting a unique dataset of professional forecasters who update their inflation forecasts at days of their choice. In the data we observe how many forecasters update (extensive margin of updating), the magnitude of the update (intensive margin), and the objective of optimization (forecast accuracy). There are also “shifters” in incentives: A contest that increases the benefit of accurate forecasting, and the release of official data that reduces the cost of processing information. These features allow us to link observables to attention and incentive parameters. We structurally estimate a model where the decision to update and the magnitude of the update are endogenous and the latter is the outcome of a rational inattention optimization. The empirical findings provide support for the key implication of rational inattention that information-processing efforts react to changing incentives. Counterfactuals reveal that accuracy is maximized if the contest date coincides with the release of information, aligning higher benefits with lower costs of attention.
