I formalize the decision-making of those who contemplate suicide for economic reasons. In so doing, I take into account their option to postpone the action of committing suicide, which is typically ignored in the theoretical literature on economics of suicide. I numerically simulate the model, showing that an increased risk of income fluctuations results in a rise of the minimum level of income required for the youth suicide prevention as well as that for the elderly suicide prevention. The simulation result also shows that the former rise is faster than the latter. I extend the model by introducing two types of unemployment benefits for suicide prevention. One is that the amount of benefits is prefixed. The other is that the amount of benefits is proportional to the individual level of income prior to the job loss. I compare these two types, concluding that the fixed amount of benefits is better than the amount proportional to income for suicide prevention.

我正式化了那些出于经济原因考虑自杀的人的决策。这样，我考虑了他们推迟自杀行动的选择，这通常在关于自杀经济学的理论文献中被忽略。我在数值上模拟了该模型，表明收入波动的风险增加导致预防青年自杀所需的最低收入水平以及预防老年人的自杀。模拟结果还表明，前者的升高比后者快。我通过引入预防自杀的两种失业福利来扩展模型。一个是，福利的数量是前缀。另一个是，福利量与失业之前的收入水平成正比。我比较了这两种类型，得出的结论是，固定额的收益远高于与预防自杀的收入成正比的金额。
