Abstract
Since implementing the one-child policy in the early 1980s, China has successfully controlled
its population growth rate. However, this policy brought together some side effects,
one of which is the unbalanced sex ratio. By the year 2000, China had 40.9 million more
men than women. The large gender gap has affected both the labor market and the marriage
market. We will present a model in which the labor market and the marriage market
interact to determine pre-marital education, and in which the numbers of men and women
are assumed to be equal. Moreover, we present the mathematical background underlying
the economics model. We prove that in a matching market such as the marriage market,
there always exists a stable assignment between the two groups of participants. We will adjust
the model by relaxing the equal number assumption to predict the impact of China’s
unbalanced sex ratio on people’s investments in pre-marital education. With more men
than women, men will reduce their investments in pre-marital education while women will
increase their investments in pre-marital education.
