Mitigating overinvestment in Japanese zombie firms: the role of foreign ownership and earnings quality

Purpose This study investigates the relationship between foreign ownership, earnings quality and overinvestment in Japanese zombie firms. Design/methodology/approach The study makes use of data from Japanese firms listed on the first section of the Tokyo Stock Exchange from 2009 to 2019. The study employs logistic and multinomial logistic models to test whether the overinvestment behavior of zombie firms is mitigated by foreign shareholdings and earnings quality. Findings The results show that (1) zombie firms tend to overinvest; (2) an increase in foreign ownership mitigates the overinvestment of zombie firms and (3) the mitigation of zombie firms' overinvestment by foreign ownership is stronger with higher earnings quality. Originality/value This study extends the discussion of earnings quality and investment efficiency to the zombie firm setting. Previous studies in accounting suggest that high earnings quality enhances firms' investment efficiency. The findings suggest that both a change in ownership structure and high-quality accounting information are necessary to mitigate the inefficiency of zombie firms.
