This paper studies how sex imbalance in the marriage market affects the timing of the first marriage. As a major relaxation of the one-child policy in China during the 1980s, the “one-and-a-half-children” policy was implemented to allow extra births, conditional on the gender of the first child. Rural residents are allowed to have a second child only if the first child is female. Due to the stronger son preference at higher order births, this policy change increases the incentive of parents to have male children rather than female children and conduct sex-selective abortions. Thus, this led to a male-biased sex ratio at birth in the 1980s and an excess supply of males in marriage market after 2000. Based on data from China Family Panel Studies 2014 and the Chinese Census 2000, I estimate the effect of sex ratio on the timing of the first marriage by exploiting the exogenous variation of the policy implementation across regions and cohorts. From a difference-in-difference approach with mixture proportional hazard models, I find that the first marriage is significantly delayed in regions with a high sex ratio. The delaying effects are significant for both males and females, though less significant and smaller for females. The fact that females also delay the first marriage is because they set a higher reservation wage in response to an excess supply of males in the marriage market.
