Data from two surveys of twins in China are used to contribute to an improved
understanding of the role of economic development in affecting gender differences in the
trends in, levels of, and returns to schooling observed in China and in many developing
countries in recent decades. In particular, we explore the hypothesis that these
phenomena reflect differences in comparative advantage with respect to skill and brawn
between men and women in the context of changes in incomes, returns to skill, and/or
nutritional improvements that are the result of economic development and growth.
