一旦发生严重灾害，许多受害者可能同时失去生命。人的一生都面临着灾难的风险，也永远无法摆脱。其中，本研究专门关注灾难致命风险的两个不同特征：背景性和不可逆性。防灾投资是降低人们在灾害中可能死亡的致命风险的基本手段。本文建立了一个考虑灾害风险的动态最优消费模型，分析了致命风险的降低如何影响消费者对复合商品和寿险的需求。防灾投资的经济效益可以通过调查代表性消费者从他/她的终身消费计划中获得的效用流的现值如何受到致命风险变化的影响来衡量。
Once serious disaster occurs, many victims may simultaneously lose their lives. One is always under disaster risks and is never free from them throughout one's life. Among others, this study exclusively focuses upon two distinct features of fatal risks by disaster: backgroundness and irreversibility. The disaster prevention investment is the basic means to reduce the fatal risks that people may be killed in disaster. In the paper, a dynamic optimal consumption model with disaster risks is formulated to analyze how the consumer's demands for composite goods and life insurance are modified by reduction of the fatal risks. The economic benefits of disaster prevention investment can be measured by investigating how the present value of the stream of utility that the representative consumer can derive from his/her life-long consumption plan, is influenced by change in the fatal risks.
