60–69歳の高齢者を対象とした調査個票に基づき, 在職老齢年金制度による就業抑制効果が（63歳と64歳の一部の結果を除き）2009年時点で確認できないこと, 老齢厚生年金受給資格者で基礎年金繰上げ支給制度を利用しているのは定年などによる離職後に失業を経験した人々に多いこと, 基礎年金繰上げ支給制度を利用した人々の相対的貧困率は, 利用しなかった人々の3倍にも上り, 繰上げ支給制度が所得確保の手段として万能薬でないことなどを明らかにした。
Based on individual survey data on the older people aged 60 to 69, this study demonstrates that the labor supply disincentive effect induced by the income test of old age Employees' Pension (EP) systems (except for part of the 63 year-old and 64 year-old results) cannot be observed as of 2009; the early withdrawal of basic pension, in the case of the eligible people for EP. –were associated with the experience of unemployment after their mandatory retirement; the incidence of relative poverty amongst the people, who utilize the early withdrawal rule, is up to three times the number of those who did not use the rule and it, indicates that the early withdrawal rule of basic pension system is not a panacea as a means for ensuring income of those who are eligible for EP.
