Legitimation of earnings inequality between regular and non-regular workers: A comparison of Japan, South Korea, and the United States

This study explores functions of labor market institutions in perpetuating earnings gap between different categories of workers with focusing on people’s views of earnings gap between regular and non-regular workers in Japan, South Korea, and the United States. An original cross-national factorial survey was conducted to measure the extent to which respondents admit earnings gap among workers with different characteristics. We found that Japanese and South Korean respondents tended to justify the earnings gap between regular and non-regular workers. In Japan, non-regular-worker respondents accepted the wide earnings gap against their economic interests, which was explained by assumed difference in responsibilities and on-the-job training opportunities. Specific institutional arrangements contribute to legitimating earnings gap between different categories of workers by attaching status value to the categories.
