Son preference, children's gender and parents' time allocation: evidence from China

This article investigates the effect of children's gender on parents' time allocation in developing countries due to the long-existing tradition of son preference. A collective model generates predictions concerning the impact of the birth of sons on family behaviour when son preference is treated as a premium in the father's utility function. Using data from China, I show that, with more sons instead of daughters, the time spent by both men and women on housework rises, while men have to increase their work time in the labour market and women can reduce theirs. The results are consistent with theoretical predictions and are robust for use in further tests. For the possible endogeneity of children's gender, I use the law forbidding the use of ultrasound-B to reveal the gender of a foetus as instrumental variables as the identification strategy.
