RT Journal Article SR Electronic T1 The “Missing Girls” of China and the Unintended Consequences of the One Child Policy JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 87 OP 115 DO 10.3368/jhr.45.1.87 VO 45 IS 1 A1 Ebenstein, Avraham YR 2010 UL http://jhr.uwpress.org/content/45/1/87.abstract AB High ratios of males to females in China have concerned researchers (Sen 1990, Yi et al. 1993) and the recent increase has alarmed policymakers worldwide. This paper presents an analysis of China’s census data that indicates that the “missing girls” phenomenon is causally linked to enforcement of the One Child Policy. Fertility is lower and sex ratios are higher among those under stricter fertility control, and the overall increase in the sex ratio is driven by an increase in the prevalence of sex selection among first and second births. By exploiting regional and temporal variation in fines levied for unauthorized births, I find that higher fine regimes discourage fertility, but are associated with higher ratios of males to females.
