We investigate the impacts of two disasters in Japan and the Philippines on preferences using the convex time budget experiments and multiple price list experiments with monetary rewards. By exploiting natural experiments which are combined with lab-in-the-field experiments, we aim to investigate whether and how long preferences are affected by extreme events. We find evidence supporting preference instability caused by exposure to natural hazards: in both our study sites, disaster exposure seems to make individuals more present-biased even though they differ in socioeconomic conditions and disaster types. The estimated impacts are persistent over the short and long time intervals in both disaster-affected areas and are robust to the method of measuring preferences.
我们使用带有货币奖励的凸性时间预算实验和多重价格列表实验，研究日本和菲律宾的两场灾难对偏好的影响。通过利用与实地实验相结合的自然实验，我们旨在研究偏好是否以及在多长时间内会受到极端事件的影响。我们发现有证据支持因接触自然灾害而导致的偏好不稳定：在我们的两个研究地点，尽管社会经济状况和灾害类型不同，但接触灾害似乎会使个体更倾向于即时偏好。在两个受灾地区，估计的影响在短期和长期内都持续存在，并且对于测量偏好的方法具有稳健性。
