Abstract
Abstract Does single pregnancy adversely affect infant health? This is a challenging research question because there is selection in coresidence during pregnancy. We exploit quasi-natural variation in single pregnancy from the moment of conception to birth, arising from the reform of the marriageable age laws in Korea. The Korean birth certificate data are unique. They provide the information about the coresidence status in addition to the legal marital status. The coresidence start date allows us to identify the intensity of coresidence during pregnancy. We find that coresidence or legal marriage during pregnancy does not significantly affect birth outcomes.
期刊介绍：
Demographic variables such as fertility, mortality, migration and family structures notably respond to economic incentives and in turn affect the economic development of societies. Journal of Demographic Economics welcomes both empirical and theoretical papers on issues relevant to Demographic Economics with a preference for combining abstract economic or demographic models together with data to highlight major mechanisms. The journal was first published in 1929 as Bulletin de l’Institut des Sciences Economiques. It later became known as Louvain Economic Review, and continued till 2014 to publish under this title. In 2015, it moved to Cambridge University Press, increased its international character and changed its focus exclusively to demographic economics.
