AI 中文摘要
计量经济学中有大量文献基于事前标准（如最小化最大遗憾值）提出具有最优性保证的决策规则。我们构建了一个分析此类规则动态一致性的框架，并表明在许多实证相关情形下，研究者在观测到数据实现后可能希望偏离事前最优规则的中期规定。为解决此问题，我们提出并公理化了两类产生动态一致决策规则的最优性标准。
英文摘要
A large literature in econometrics proposes decision rules with optimality guarantees based on ex ante criteria, such as minimax regret. We develop a framework for analyzing the dynamic consistency of such rules and show that, in many empirically relevant settings, the researcher may wish to deviate from the interim prescription of ex ante optimal rules after observing the data realization. To address this problem, we propose and axiomatize two classes of optimality criteria that yield dynamically consistent decision rules.
