Dynamic Inconsistency in Food Choice: Experimental Evidence from Two Food Deserts
通过两个家庭食品配送项目的实地实验，研究人们在食物选择中的动态不一致性（提前选择与即时选择不一致）以及对承诺机制的需求，发现约半数参与者愿意使用承诺工具，但自我控制问题越大的人越不意识到自己的问题。
Abstract We conduct field experiments to investigate dynamic inconsistency and commitment demand in food choice. In two home grocery delivery programs, we document substantial dynamic inconsistency between advance and immediate choices. When given the option to commit to their advance choices, around half of subjects take it up. Commitment demand is negatively correlated with dynamic inconsistency, suggesting those with larger self-control problems are less likely to be aware thereof. We evaluate the welfare consequences of dynamic inconsistency and commitment policies with utility measures based on advance, immediate, and unambiguous choices. Simply offering commitment has limited welfare (and behavioural) consequences under all measures.
