Several reasons underlie the increased labour participation of older people in Japan. One reason is the subsidy for the labour supply of elderly people. This article presents an examination of how this subsidisation of the labour supply of elderly people affects the labour participation of young and elderly people and unemployment. Consequently, an aging society brought about by an increase in the survival rate and the subsidy for elderly labour raise the employment rate and labour participation rate of elderly people in a temporary equilibrium model. This result is consistent with the real world. However, considering the steady state in a closed economy under which capital accumulation is considered, the effect of this subsidy on the employment rate and labour participation of elderly people is slight because of a decrease in the wage rate.

有几个原因是日本老年人增加劳动参与的原因。原因之一是对老年人的劳动力供应的补贴。本文探讨了对老年人劳动力供给的这种补贴如何影响年轻人和老年人的劳动参与以及失业。因此，在临时均衡模型中，由于成活率的提高和对老年人劳动的补贴而导致的老龄化社会提高了老年人的就业率和劳动参与率。这个结果与现实世界是一致的。但是，考虑到在封闭的经济中考虑资本积累的稳定状态，由于工资率的降低，这种补贴对老年人的就业率和劳动参与的影响很小。
