Outline of Final Research Achievements

Through empirical studies on several microdata sets, we showed that increases in non-regular employment beginning in the 2000s were accompanied by employment status persistence. As a result, a dual structure consisting of regular and non-regular employment has taken form in the Japanese labor market. Regular employment is characterized by seniority wages and wage premiums, while non-regular employment suffers restricted opportunities for wage increase. The regular employment market is rationed and thus labor mobility between these two markets is limited. This dual structure has changed employment adjustment among firms and, in response to economic shocks, has expanded the reallocation of non-regular employment.
