本文基于2013年通过日本互联网调查收集的家庭数据，研究了个人对救灾物资到达时间(即感知到达时间)的主观感知是否以及在多大程度上影响了家庭对自然灾害的应急饮用水准备行为。我们的估计结果表明，感知到达时间对家庭库存的EDW非常重要，并且随着感知到达时间的增加，EDW的数量可能会大大增加。此外，与不太容易发生风险的地区的家庭相比，风险易发地区的家庭储存了更多的EDW。感知到达时间可以被解释为一种风险感知，我们的结果说明了所谓的风险感知悖论的反例。
This paper addresses whether and to what extent individual subjective perception of the time it takes for disaster relief supplies to arrive (i.e., perceived arrival time) affects households’ emergency drinking water (EDW) preparedness behavior for natural disasters, based on household data originally collected through an internet survey in Japan in 2013. Our estimation results show that perceived arrival time significantly matters for household stocks of EDW and that the amount of EDW could be greatly enhanced as perceived arrival time increases. Moreover, households in risk-prone areas stock more EDW compared with households in less risk-prone areas. Perceived arrival time can be interpreted as a kind of risk perception, and our results illustrate the counterexample of the so-called risk perception paradox.
