Wage distribution in Japan, 1989–2003

Abstract

Diverging economic inequality has become a common focus of economic debate in developed countries. In particular, the recent experience of Japan has started attracting international attention. We take advantage of a rich micro-level data set from the Basic Survey on Wage Structure (1989Structure ( -2003 to perform an in-depth analysis of the change in the inequality and distribution of the hourly wage. We observe that lower returns to education and years of tenure contribute to diminishing income disparity between groups for both sexes. A larger variance within a group contributes to the wage disparity for males, while an increased heterogeneity of workers' attributes contributes to the wage disparity for females. The Dinardo, Fortin, and Lemieux decomposition also confirms the basic findings from a parametric variance decomposition.

Does labor legislation benefit workers? Well-being after an hours reduction

“…Another possibility is that the returns to schooling and experience, both variables that raise the imputed π, rose during this period. In Japan, as the estimates in Kambayashi et al (2008) show, exactly the opposite happened; and in Korea an examination of wage ratios between various 15 The re-estimates of (2b) for the Pre-Pre and Pre periods yield results for women that are similar to those shown for Korea in Table 5. Among men the significant negative trend in that Table disappears in those re-estimates: The estimated β 3 is tiny and statistically insignificant.…”

Equal Employment Opportunity Law and the gender wage gap in Japan: A cohort analysis

“…A recent study by Kambayashi et al (2008) uses microdata of BSWS and contains a detailed description of the BSWS survey method. 6 The four levels of education are junior high school graduate (9 years of compulsory schooling), senior high school graduate (12 years of schooling), junior college graduate (usually 14 years of schooling, including some vocational and technical schools), and university graduate (16 years or more of schooling, including graduate education).…”

The labor market in Japan, 2000–2016

“…Compared to the US, both the 90 −50 ratio and the 50−10 ratio are lower, indicating that Japan's wage distribution is relatively more concentrated around the median. The contrasts between the two countries can be partly accounted for by relatively rapid supply growth of college-educated workers in Japan, which has suppressed a wage gap between college graduates and high school graduates [4], [5]. Wage inequality among full-time workers is evidently larger for men, possibly reflecting relatively recent wage growth among them.…”
