Chapter 9 examines son preference and its effect on the male marriage squeeze in China. The authors first review the rural_urban and parity differences and the recent trend in China’s sex ratio at birth (SRB). They also introduce an estimate of China’s missing girls and investigate the male marriage squeeze together with the projected number of surplus males in the marriage market. Next, they discuss a number of issues related to marriage squeeze in China, including the increase in bride price and wedding expenses, increased bargaining power of females in the marriage market, female marriage migration, and bare branch villages. Their empirical study is supported by rich data from China.
