The Research Network on Intergenerational Mobility (RNIM) is an initiative by scholars working on intergenerational mobility. The aim of the network is to provide a platform for both senior and junior researchers to discuss and disseminate the findings from their ongoing research projects on intergenerational mobility. The network will organize a virtual seminar every month.
Each seminar consists of a 60-minute presentation followed by a moderated Q&A session within a 75-minute Zoom conference. Participants can ask clarifying questions through the moderator during the presentation.
Highlight of this month

This study provides the first comprehensive analysis of absolute intergenerational mobility (AIM) in Hong Kong, using census data spanning four decades. Employing the “copula and marginals” method, the authors document a sharp decline in AIM, from 85% for the 1976 birth cohort to 49% for the 2001 cohort, driven largely by diminished labor income mobility. The erosion stems primarily from slower economic growth rather than rising inequality; under constant economic growth, AIM would stabilize at approximately 67%, accounting for nearly all of the decline, with minimal residual from inequality or copula changes. The findings are robust across specifications, and an innovative Mincer equation–based decomposition highlights education’s critical role in mitigating declines, offering general insights into how tertiary expansion shapes mobility in transitioning economies.
