Abstract

|
This article comes up with theoretical hypotheses about fertility differentials among Korean wives and foreign wives and, more specifically, about effect heterogeneities by their countries of origin. We formulated those hypotheses based on the mix of the immigrant fertility literature and the assortative mating literature, espousing the viewpoint of fertility from a couple perspective. Those hypotheses are tested by fitting data from the 2012 National Fertility Survey and the 2012 National Survey of Multicultural Families to Cox proportional hazard models and discrete-time hazard models. We find that Korean-Chinese and Chinese wives exhibited lower fertility hazards for the first childbirth than Korean wives while Vietnamese and Filipina wives registered similar levels with Korean wives. Regarding the second childbirth, only Korean-Chinese wives showed lower fertility hazards than Korean wives. These empirical findings support the theoretical intersection between the socialization hypothesis from the immigrant fertility literature and the deficit hypothesis from the
assortative mating literature. We discuss implications and limitations of our findings and lay out recommendations for future studies.
