Full TextAbstract
We conduct a natural field experiment with over 200 customers at a grocery
store to investigate dynamic inconsistency and the demand for commitment in
food choice. Subjects are invited to allocate and re-allocate food items received as part of a grocery delivery program. We observe substantial dynamic inconsistency, as well as a demand for commitment among a non-negligible number
of subjects. Interestingly, individuals who demand commitment are more likely
to be dynamically consistent in their prior behavior. This work provides direct
evidence of dynamic inconsistency in consumption choices in the field and points towards potential extensions to models of temptation.
