In this paper, we examine the effect of maternal education on the health of young children by using a large sample of adopted children from China. As adopted children are genetically unrelated to the nurturing parents, the educational effect on them is most likely to be the nurturing effect. We find that the mother's education is an important determinant of the health of adopted children even after we control for income, the number of siblings, health environments, and other socioeconomic variables. Moreover, the effect of the mother's education on the adoptee sample is similar to that on the own birth sample, which suggests that the main effect of the mother's education on child health is in post-natal nurturing. Our work provides new evidence to the general literature that examines the determinants of health and that examines the intergenerational immobility of socioeconomic status.

In interpreting the positive relationship between spousal education and one’s earnings, economists have two major hypotheses: cross-productivity between couples and assortative mating. However, no prior empirical study has been able to separate the two effects. This paper empirically disentangles the two effects by using twins data that we collected from urban China. We have two major innovations: we use twins data to control for the unobserved mating effect in our estimations, and we estimate both current and wedding-time earnings equations. Arguably, the cross-productivity effect takes time to be realized and thus is relatively unimportant at the time of the wedding. Any effect of spousal education on wedding-time earnings should more likely be the mating effect. We find that both cross-productivity and mating are important in explaining the current earnings. Although the mating effect exists for both husbands and wives, the cross-productivity effect only runs from Chinese husbands to wives. We further show that the cross-productivity effect is realized by increasing the hourly wage rate rather than working hours.

In China, a growing awareness that many areas have been left behind during an era characterized by market reform has raised concerns about the impact of community disadvantage on schooling. In this paper, I investigate whether villages exert distinct influences on student achievement. Building on these results, I explore the relationship between student achievement and resources present in the community. Results indicate that children who live in communities with higher levels of economic and social resources have higher mathematics scores, on average.

This paper empirically estimates the returns to education using twins data that the authors collected from urban China. Our ordinary least-squares estimate shows that one year of schooling increases an individual’s earnings by 8.4 percent. However, once we use the within-twin-pair fixed effects model, the return is reduced to 2.7 percent, which suggests that much of the estimated returns to education in China that have been found in previous studies are due to omitted ability or the family effect. This finding suggests that well-educated people are faring well in China mainly because of their superior ability or family background advantages, rather than because of knowledge that they acquired at school. We further investigate why the true return is low and the omitted ability bias high, and find evidence that it may be a consequence of the distinct education system in China, which is highly selective and exam oriented. More specifically, we find that high school education mainly serves as a mechanism to select college students, and has zero returns in terms of earnings. In contrast, both vocational school education and college education have a large return that is comparable to that found in rich Western countries.

This paper examines the emergence of labour markets in China through the lens of returns to rural education. It demonstrates that methodology plays an important role in explaining the low estimates of returns in previous studies. When wages are defined on an hourly basis and sample selectivity is controlled, estimated rates of return rise. In addition, using data on households (n=1199) followed over 15 years (1988-2002), the paper shows that returns have risen over time. Finally, using households from the same community, it is shown that the returns rise even more when the sample includes workers with demographic and employment profiles more like those in the rest of the world (i.e., young and working in urban areas). In fact, the paper finds that the returns to education are close to 10% for young wage earners. When looked at in total, the results show that the returns to rural education in China are completely consistent with other developing countries. Finally, these results indicate that China's labour markets are becoming more functional over time.

The overall goal of this paper is to contribute to the ongoing assessment of China’s rural labor markets. To meet this goal, we have three specific objectives. First, we will provide an update of the trends in off-farm labor participation and wages of the sample households and examine how labor market outcomes have changed for those with different levels of education. Second, we will then seek to examine if education in different time periods – the late 1980s, the early 1990s and the mid 1990s -- can be associated with increasing access to off-farm jobs. Finally, we will examine how returns to education have changed during the course of the reform era. In short, our hypotheses are that if labor markets are increasingly rewarding those with a.) better education job access; b.) easier entry; and c.) higher wages, such outcomes will count as evidence that labor markets are improving. Both the descriptive data and the multivariate analysis robustly support the findings that between the late 1980s and the mid-1990s, labor markets have improved in the sense that rural workers have been increasingly rewarded for their education.
