Earnings Mobility in Korea

Abstract

We measure the degrees of earnings mobility in Korea, which is defined as the rate of changes of relative income ranking over two terms, with a conventional panel subject to measurement error and non-random attrition and a pseudo panel. The different degrees of earnings mobility from two panels were appllied to the empirical detection of poverty traps. 본 논문은 한국의 세대내 소득이동성(earnings mobility)을 추정한다. 패널자료의 문제 점인 비무작위적 탈락(non-random attrition)과 측정오차(measurement error)를 보정하기 위해 가패널 방법론(pseudo-panel approach)을 사용하고, 통상패널자료의 추정편의를 빈 곤함정(poverty trap)에 적용해 논의한다
