| Research Abstract |
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.
