Abstract

This paper estimated the first-born effects on wage among wage and salary workers born in 1954 to 1973 with the 2003 KLIPS data set. The first-born effect on wage was estimated as 7.3% with the parsimoniously specified wage function using age and gender. Adding various variables as independent variables, the effects were estimated statistically insignificantly differently, the effect was estimated as 7.6% with adding education, tenure, marital status, father's education, the number of siblings, and health. The effect is not statistically significantly different from that of the parsimoniously specified wage function. We estimated the first-born effects of male, and female wage and salary workers separately. The first-born effects of male wage and salary workers were estimated as 5.9~8.8%. The first-born effects of female wage and salary workers were estimated as 8.8~9.9%.

2003년 KLIPS 자료를 사용하여 1954년부터 1973년에 태어난 임금근로자들에게 있어서 맏이(first-born)의 임금에 대한 효과를 추정하였다. 연령, 여성 등만을 사용한 절제된 임금함수로부터 추정된 맏이 효과는 7.3%였으며 교육연수 등 다양한 변수들이 추가되어도 이 추정계수는 통계적으로 유의한 차이가 없었고 교육연수, 근속연수, 결혼 여부, 아버지의 교육연수, 형제자매 수, 건강 등을 통제하면서 추정된 맏이 효과도 7.6%로 거의 차이가 없었다. 임금근로자를 남자와 여자로 나누어서 추정하면 맏형의 임금이 남동생들의 임금에 비해 5.3~6.9% 높으며, 맏언니의 임금이 여동생들에 비해 8.8~9.9% 높은 것으로 추정되었다.
