Econometric Analysis of Internal Wage Structure, Comparison between Japan and Korea

本研究的目的是基于日本和韩国的微观数据，尝试对内部工资结构进行计量分析，并对企业内部不同职业之间的劳动力流动进行比较分析。主要研究结果如下：1.年龄因素比人力资本因素(如外部经历和内部经历)更能解释内部工资结构。这可被解释为表明，在解释日本和韩国的工资结构时，应考虑到按年龄补偿生活费。相反，与日本的经验相反，年龄决定的工资结构意味着劳动力市场的流动性很高。因此，对于日本劳动力市场流动性较低的解释，我们不得不假设存在任何制度性障碍，如有利于Kogai员工(在其他公司没有工作经验的处女工人)的晋升规则。日本、韩国和美国之间的比较表明，没有经验证据支持被广泛接受的观点，即日本的企业内部劳动力市场比其他国家更具流动性。

The purpose of this research is to attempt econometric analysis of internal wage structure and also to make comparative analysis of intra-firm labor mobility between occupations, on the basis of micro-data which are available for Japan and Korea. Major findings are as follows;1. Internal wage structure can better be explained by age factor than by human capital factors such as external and internal experiences. This could be interpreted as indicating that living cost compensation by age should be taken into account in explaining Japanese and Korean wage structure.2. Contrary, to the Japanese experience, age-determined wage structure suggests highly mobile labor markets. Therefore, for the explanation of less mobile Japanese labor market's, we have to assume the existence of any institutional barriers such as promotion rule favorable to Kogai employees (virgin workers without work experience at other firms).3. Comparison between Japan, Korea, and the United States reveals that there is no empirical evidence to support the widely accepted view that intra-firm labor market is more mobile in Japan than in other countries.
