概要	This study investigates preference parameter changes after a natural disaster by using observational data. The heterogeneous preference parameters in a structural model is estimated by an existing measurement error robust approach, where assumptions set on measurement errors are tested by a novel moment inequality approach proposed in this study. We find that the disaster affects households' preference parameters heterogeneously, depending on households' future risks of facing a similar disaster-households facing a high risk become more risk averse compared with those facing a low risk. Our simulation results suggest that consumption predictions can be improved by using updated preference parameters.
