Outline of Research at the Start

本研究は、企業の従業員の年齢構成、特に従業員の高齢化が企業金融に与える影響を実証的に解明する。勤労世代の高齢化は先進国共通の現象ではあるが、従業員の高齢化が企業金融、より具体的には企業価値や企業投資に与える影響に関しては、先行研究の蓄積は十分とは言えない。本研究は、政府統計及び企業財務データを用いて従業員の年齢構成が企業金融に与える影響を分析する。推定結果から望ましい高齢者雇用に対する政策的含意を導く。

Outline of Final Research Achievements

We investigate whether protecting the employment of older workers affects firm value. To do so, we exploit a labor market reform in Japan, which required firms to continue employment of existing older workers beyond the statutory retirement age if they wished to work. Our event study analysis shows lower short-run abnormal returns surrounding the reform announcement in firms with higher treatment intensity. Long-run difference-in-differences analyses provide corroborative evidence. Average worker wage increased in those firms, but worker productivity did not change after the reform, suggesting a negative effect of delayed retirement of older workers on firm value when employment is protected.

Academic Significance and Societal Importance of the Research Achievements

高齢者の継続的な雇用を企業に義務付ける法改正の背景には、年金財政の逼迫を受けて公的年金の支給開始年齢が1970-80年代から徐々に引き上げられてきている事実がある。この法改正の潜在的な問題点は、国が運営する公的年金の負担を、企業に雇用を継続させる形で企業に負担をシフトする点にある。年金支給開始年齢の引き上げに対応して、高年齢層の継続雇用措置を義務化することは、日本企業の業績、企業価値、更には日本経済の成長率、等に今後どのような影響を与えるのであろうか?本研究はこれらの議論に対して1つの視点を与えるものと考えている。
