论文摘要
J. M. Keynes提倡的非自愿失业的存在是现代经济理论的一个非常重要的问题。使用三生成重叠的世代模型，我们表明，非自愿失业的存在是由于经济的不稳定所致。经济的不稳定是全部就业平衡周围平衡价格的差异方程式的不稳定性，这意味着由于存在非自愿失业而导致的名义工资率下降进一步降低了就业。这种不稳定性是由于消费者的净储蓄（储蓄和养老金之间的差异）所产生的负面真实平衡效应所致，其债务乘以儿童消费中消费的边际倾向。
The existence of involuntary unemployment advocated by J. M. Keynes is a very important problem of the modern economic theory. Using a three-generations overlapping generations model, we show that the existence of involuntary unemployment is due to the instability of the economy. Instability of the economy is the instability of the difference equation about the equilibrium price around the full-employment equilibrium, which means that a fall in the nominal wage rate caused by the presence of involuntary unemployment further reduces employment. This instability is due to the negative real balance effect that occurs when consumers' net savings (the difference between savings and pensions) are smaller than their debt multiplied by the marginal propensity to consume from childhood consumption.
