The paper tries to study the intergeneratioal trend of economic activities participation, given that youth unemployment became a societal issue under economic stress. Provided that employment equality among generations contributes social integration, the study examines if there is an unbalance of the employment. By using Age-Period-Cohort Analysis with Hysteresis Effect, three sample groups of 25-year long data such as total sample, man sample, and woman sample group are empirically tested.
The effects on the employment rates and unemployment rates reveal that the three effects, or age effects, year effects and cohort effects are statistically significant. The magnitude of the effects is age effects, year effects, and cohort effects in order from the top to the bottom. There has been the job conflicts between the aged generation aged 65 over and the youth generation aged under 30. Man workers are more likely to be layed off as they get older, while woman workers are not. The model with a control variable of workforce indicates that an increase in the workforce raises more employment for the cohort from 1954 to 1989, while the rise makes unemployment worse for the cohort from 1984 to 1989. There is a clear indication that, as older workers increase in labor market, younger workers experience the reduced number of jobs. Korea government needs to intervene the youth participation reduction in economic activities and especially the low employment for younger women.
