| 内容記述 | This study used panel data of Japan’s listed companies to examine labor union effects on intra-firm wage dispersion. Many earlier questionnaire surveys of workers across firms revealed that unions have some role in reducing wage dispersion. Nevertheless, few studies have explored such effects. In recent years, in contrast to the weakened influence of unions observed in Japan and in many other countries, institutional investors or foreign investors, so-called “activist shareholders” have increased their shareholding ratios and have reinforced their influence on management of the firms in which they invest. We specifically examine whether unions have reduced wage dispersion and whether this effect has changed over time. We also investigate whether corporate governance structure produces similar effects by adding investigations of complementarity and substitutability between unions and shareholders. By combining three data sources, we created a panel dataset including data for 2004--2015. As explained variables, the following three measures of wage dispersion among employees at age thirty are used: (1) difference between the highest and lowest wages, (2) difference between the highest wage and mean wage, and (3) difference between the lowest wage and mean wage. Explanatory variables are the union dummy (UNION) indicating 1 if a firm has at least a union and 0 otherwise, a shareholding ratio by foreign investors (FOREIGN), and that by financial institutions (FINANCIAL), and other control variables. Because the union status is nearly unchanged during investigation, we tackle this problem to employ the hybrid model and the ordinary random effects model. Descriptive statistics show that wage dispersion is slight in firms with unions for all these measures. We obtained the following results. First, UNION is negative and significant for all measures of wage dispersion. In contrast, results obtained using the hybrid model show that UNION is negative and significant only for the between effect, not for the within effect. Second, the effect of FOREIGN is positive and significant overall. Results elicited from the hybrid model show not only that FOREIGN is positive and significant but also that FINANCIAL is negative and significant. Third, the interaction term between UNION and the yearly trend term is positive and significant only for the within effect. This finding implies that the wage gap reduction effect of unions has weakened during recent decades. Finally, the results of estimation of equations including the interaction terms between UNION and FOREIGN or FINANCIAL imply that unions weaken the positive effect of foreign investors on wage gaps and that they weaken the negative effects of financial institutional shareholders. We summarize our obtained results hereinafter. First, the wage reduction effects of unions extended for about ten years during 2004--2015. Second, the hypothesis that the union effects on decreasing wages changed during the period is supported by results of statistical analysis. Third, some substitutability exists between foreign and financial institutional investors and labor unions. |
