物品的价值取决于揭示物品本质的个人体验。本研究调查了 2011 年东日本大地震和海啸灾难造成的水资源短缺对日本水资源丰富的大槌镇社区水井自愿管理的影响。 2015年进行了基于选择实验（CE）框架的问卷调查，共有127名居民参与。然后使用两种类型的 Logit 模型对响应进行分析，这些模型考虑了调查参与者之间的偏好异质性。结果显示，缺水的严重程度和持续时间对人们对水井的态度产生相反的影响。更具体地说，由于无法获得水而导致的日益严重的缺水使人们对水井的支持度降低，而由于水资源获取有限而导致的长期缺水使人们更加支持水井。
The value of a good is contingent on an individual’s experience that reveals the nature of the good. This study investigates the effects of a water shortage due to the Great East Japan Earthquake and Tsunami Disaster in 2011 on the voluntary management of community wells in the water-rich town of Otsuchi, Japan. A questionnaire survey based on a choice experiment (CE) framework was conducted in 2015 in which a total of 127 residents participated. The responses were then analyzed using two types of logit models that consider preference heterogeneity across survey participants. The results revealed that the severity and duration of the water shortage had opposing effects on people’s attitudes toward the wells. More specifically, increasingly severe water shortages due to the unavailability of water rendered people less supportive of the wells, whereas water shortages of a longer duration caused by limited access to water resources made people more supportive.
