The effect of defined contribution pension plan on firm's financial status, household's savings action, and financial market.

本研究的目的是从家庭部门、企业部门和宏观经济的角度验证日本推出固定缴费养老金计划的效果。第一个研究使用一个两阶段的一般均衡模型，探索企业可能破产对其自身工资方案和劳动力市场结构的影响。因此，那些幸运地找到了初级市场工作的人和那些没有找到工作的人之间出现了显著的效用差异，尽管他们天生的能力没有区别。我们已经获得了新白皮书中关于401K养老金引入的文章所在的93家企业的名单。获取了报刊出版前后的股价数据，并对401K养老金出台的消息对股价、企业价值的变化进行了研究。因此，我们无法确定推出DC计划对提高股票价格的效果。利用2002-2006年的《家庭预算调查》数据，检验了日本DC养老金制度对家庭储蓄的影响。因此，增加养老金财产的可能性在高收入劳动家庭群体中表现出来。此外，在高收入家庭中，缴款限额的修订可能会侵犯总储蓄。在每一种情况下，DC养老金制度增加低收入家庭的养老金类型储蓄和总储蓄的效果都无法得到证实。

The purpose of this research is to verify the effect of Japanese defined contribution pension plan introduction from the viewpoint of the household sector, the business enterprise sector, and macroeconomics.1. The first research explores the implications of possible bankruptcies of firms for their own wage schemes and the structure of labor market, using a two-period general equilibrium model. As a result, a substantial utility differential emerges between those who have luckily found a job of the primary market and those who have not, although there is no difference in their innate abilities.2. We have obtained the list of 93 enterprise companies in which the article on 401k pension introduction in the new paper. The stock prices data before and after the newspaper publishing was acquired, and the news of 401k pension introduction how stock prices, corporate value, changed the event was studied. As a result, we could not confirm the effect of introducing the DC plan on raising stock prices.3. The effect of the DC pension system in Japan on the households, savings was tested by using the data of "Family Budget Survey" from 2002 to 2006. As a result, the possibility of increasing the amount of the pension property was shown in the group of high-income working households. In addition, the possibility that the revision of the contribution limit invades aggregate savings is shown among high-income households. In each case, the effect that the DC pension system increased the pension type savings and aggregate savings of low-income households was not able to be confirmed.
