Intra-generational social mobility for a young labor market entrant in Korea can be categorized into four types based on early-stage income and income development curve.
Comparing each type, the higher the beginning income is, the greater the income increase over time, confirming that income disparity widens as the economic participation period extends.
At an individual level, it is more likely that one would be part of a favorable income development curve if one is a male, is from a higher-income family, is more educated, and is hired at a conglomerate or on a permanent employment status. It is confirmed that the labor market disparity is affected by gender, education, family background, and first job.
