Evaluating Deliberative Competence: A Simple Method with an Application to Financial Choice
研究提出一种简单直观的评估方法，用于衡量金融教育等干预措施对改善决策质量的效果，能区分不同干预的真实效益，并作为福利损失的稳健度量。
We examine methods for evaluating interventions designed to improve decision-making quality when people misunderstand the consequences of their choices. In an experiment involving financial education, conventional outcome metrics (financial literacy and directional behavioral responses) imply that two interventions are equally beneficial even though only one reduces the average severity of errors. We trace these failures to violations of the assumptions embedded in the conventional metrics. We propose a simple, intuitive, and broadly applicable outcome metric that properly differentiates between the interventions, and is robustly interpretable as a measure of welfare loss from misunderstanding consequences even when additional biases distort choices.
