There is little evidence showing whether health information transmitted via text messages can change health and educational outcomes. We conducted a randomized field experiment involving 900 primary students in rural China to study whether a health education campaign conducted via text message could affect caregiver knowledge or student outcomes. When caregivers received both weekly health messages and monthly quiz questions (testing retention of the information conveyed in the weekly messages), caregiver knowledge improved and students experienced gains in both health and academic performance. When caregivers received weekly health messages only, there was no impact on caregiver knowledge or student outcomes.

We describe the degree to which household income is negatively associated with the prevalence of different types of disability (i.e. medical impairments) in China using data from the 2006 China National Sample Survey of Disabled Persons. We then calculate the extra costs of disability across different types of households and show how these costs differ by the type and severity of disability in both urban and rural areas. We finally use nationally-representative panel data on persons with disabilities from 2007 to 2009 to examine the degree to which social security measures are reaching persons with different types and severity of disabilities in both urban and rural areas. We conclude that while social assistance and insurance for households with disabilities is increasing rapidly over time, it is still not enough to offset the income differential between households with and without disabled persons, especially when accounting for the extra costs of living associated with disability.

Recent studies have shown that only about two-thirds of the students from poor, rural areas in China finish junior high school and enter high school. One factor that may be behind the low rates of high school attendance is that students may be misinformed about the returns to schooling or lack career planning skills. We therefore conduct a cluster-randomized controlled trial (RCT) using a sample of 131 junior high schools and more than 12,000 students to test the effects of providing information on returns or career planning skills on student dropout, academic achievement and plans to go to high school. Contrary to previous studies, we find that information does not have significant effects on student outcomes. Unlike information, counseling does have an effect. However, the effect is somewhat surprising. Our findings suggest that counseling increases dropouts and seems to lower academic achievement. In our analysis of the causal chain, we conclude that financial constraints and the poor quality of education in junior high schools in poor, rural areas (the venue of the study) may be contributing to the absence of positive impacts on student outcomes from information and counseling. The negative effects of counseling on dropout may also be due to the high and growing wages for unskilled labor (high opportunity costs) in China’s transitioning economy. It is possible that when our counseling curriculum informed the students about the reality of how difficult were the requirements for entering academic high school, it may have induced them to revise their benefit-cost calculations and come to the realization that they are better off dropping out and/or working less hard in school.

The rapid expansion of enrollment capacity in China’s colleges since the late 1990s has come at the price of high tuition hikes. China’s government has put forth financial aid programs to enable poor students to access higher education. Although studies have shown that poor high school students are indeed able to attend college when their test scores are high enough (that is, few are unable to attend when they are qualified to attend), the literature has not explored whether poor students have sufficient amounts of aid to thrive in college.

 Using findings from a randomized controlled trial, this study evaluates the impact of providing full scholarships to students from poor rural areas (henceforth treatment students) on student stress levels, self-esteem/self-efficacy, and participation in activities in four first-tier colleges. To do so, we compare outcomes of the treatment students with students who were not given full scholarships by the project (and were left to search for scholarships and other sources of financial aid from the university system itself—the control students). The project was run among the 200 poorest first-year students in four first-tier colleges in inland China. Somewhat surprisingly, we find that treatment students (those receiving full scholarships from the project) were only slightly more successful in obtaining financial aid than control students. This suggests that control students (those who did not receive full scholarships from the project) were still able to access comparable levels of financial aid. Most importantly, scholarship recipients were statistically identical in outcome to control students in terms of stress, self-esteem, and participation in college activities, suggesting that poor students (who are dependent on aid from the university system) currently are able to access sufficient levels of financial aid, are able to take advantage of the activities offered at college, and do not shoulder heavy financial or psychological costs.

 We find, therefore, that efforts of the government to alleviate the financial burden of college on the poor have been relatively successful in first-tier colleges. Because of this, foundations and individuals may decide that if they want to improve human welfare, giving additional scholarships at high tier colleges may be having little effect.

This paper uses a clustered randomised field experiment to explore the effects of a computer assisted learning (CAL) programme on student academic and non-academic outcomes in poor, rural public schools in China. Our results show that a remedial, game-based CAL programme in math held outside of regular school hours with boarding students in poor rural public schools improved standardised math scores by 0.12 standard deviations. Students from poorer families tended to benefit more from the programme. However, CAL did not have any significant impact on either Chinese language standardised test scores or non-academic outcomes.

The goal of this article was to document and explain the gap in educational achievement between Han and minority students in primary schools in western China. In our survey of 300 schools in Shaanxi, Gansu, and Qinghai provinces (involving nearly 21,000 fourth- and fifth-grade students), we find large differences in achievement on standardized exams between Han and minority students. On average, minority students perform 0.25 SD lower in math and 0.22 SD lower in Chinese. Most strikingly, minority students who do not generally speak Mandarin as their primary language score 0.62 SD lower than Han in math and 0.65 SD lower than Han in Chinese.

Using decomposition methods pioneered by Oaxaca (1973) and Blinder (1973), we find that most of the achievement gap between Han and minority students with no alternative ethnic language can be explained by differences in endowments of student, family, and school characteristics. Of these, differences in students and family characteristics appear to contribute the most to differences in achievement. Little of the gap between Han students and non-Mandarin minority students (Salar and Tibetan in our sample), however, can be explained by endowment differences. Comparing these students only to Han students in the same schools significantly reduces the size of the achievement gap, yet a difference of more than 0.2 SD persists. None of this remaining gap is explained by differences in endowments. Although several explanations are possible, we believe that a likely explanation is that the ability of students to learn may be hindered by difficulty comprehending instruction in Mandarin (given that no schools in our sample provided instruction or texts in minority languages). While we cannot say with certainty why these students may benefit less from a given amount of schooling inputs, our analysis suggests that teachers play a significant role.

While we believe that the findings of this article are important, admittedly, the study has a number of limitations. First, although our sample contains suf- ficient numbers of minority students to conduct analyses, studies involving a larger sample of minority students (particularly non-Mandarin minority stu- dents) would provide further insight into the achievement gap. Second, our survey did not collect information on the Mandarin ability of individual students (although we tested students on the Chinese curriculum, this may be distinct from pure language ability). Future studies should employ such information to assess to what degree language is contributing to the underperformance of students belonging to groups that do not speak Mandarin as their primary language.

Despite these limitations, however, our results call for the attention of policy makers to approaches to address the underperformance of minority students in China’s rural areas. Given the large and increasing importance of educational attainment to economic well-being, addressing the large achievement gap between Han and minority students may help to mitigate economic disparities in the future. On the basis of our results, promising approaches to address the achievement gap would include those focused on improving the returns to minority students of given schooling inputs (e.g., through pedagogical practice). Further, if future studies show language to contribute significantly to the gap, interventions such as remedial tutoring in Mandarin may also yield large benefits.

Although there is evidence that there was gender inequality in China’s education system in the 1980s, the literature in China has mixed evidence on improvements in gender inequality in educational attainment over the past three decades. Some suggest gender inequality is still severe; others report progress. We seek to understand the progress China has made (if any) in reducing gender inequality in education since the 1980s. To meet this goal, we use a meta-analysis approach which provides a new quantitative review of a relatively large volume of empirical literature on gender educational differentials. This article analyzes differences across both time and space, and also across different grade levels and ethnicities. Our results indicate that gender inequality in educational attainment still exists, but it has been narrowing over time. Moreover, it varies by area (rural versus urban) and grade level. There is nearly no significant gender inequality in the case of girls in urban areas or in the case of the 9 years of compulsory education (primary school and junior high school). Girls, however, still face inequality in rural areas (although inequality is falling over time) and when they reach high school or beyond. (JEL I24)

Officials in China claim that voting rates in rural village elections are high. Unfortunately, these rates are assumptions, not facts. The true voting rate is lower, and much lower for women. We postulate that this could be due to insufficient knowledge about their rights.

The objective of this paper is to test whether women and village leaders’ knowledge about women’s voting rights affects women’s voting behavior. We report on the results of a randomized controlled trial (RCT) involving 700 women in China’s Fujian and Liaoning Provinces. Villages were randomly assigned to either a control group or one of three intervention groups. One intervention provided voting training to women only, another provided training to both women and village leaders and the third provided training to village leaders only.

The data show that after women received training, their scores on a test of voting knowledge increased and they more fully exercised their voting rights. When only village leaders were trained, test scores and voting behaviors were not statistically different from the control villages.

A significant gap remains between rural and urban students in the rate of admission to senior high school. One reason for this gap may be the high levels of tuition and fees for senior high school. By reducing student expectations of attending high school, high tuition and fees can reduce student academic performance in junior high school. In this paper we evaluate the impact of a senior high tuition relief program on the test scores of poor, rural seventh grade students in China. We surveyed three counties in Shaanxi Province and exploit the fact that, while the counties are adjacent to one another and share similar characteristics, only one of the three implemented a tuition relief program. Using several alternative estimation strategies, including Difference-in-Differences (DD), Difference-in-Difference-in- Differences (DDD), Propensity Score Matching (Matching) and Difference-in-Differences Matching (DD Matching), we find that the tuition program has a statistically significant and positive impact on the math scores of seventh grade students. More importantly, this program is shown to have a statistically significant and positive effect on the poorest students in the treatment group compared to their wealthier peers.

Experts agree that computers and computing play an important role in education. Since the 1980s there has been a debate about gender as it relates to computers and education. However, results regarding gender differences concerning computer use in education are not consistent. In particular there is little work done in China on this issue. Therefore, the overall goal of this paper is to demonstrate whether girls and boys can gain equally from computer-based education in China’s elementary schools. To do so we analyze results from three randomized field experiments of a Computer Assisted Learning (CAL) program and one laptop per child (OLPC) program. The field experiments are carried out in three kinds of schools: Shannxi rural public schools; Qinghai minority public schools; and Beijing migrant schools. Although CAL and OLPC have been considered cost effective means to improve learning outcomes, it is not known whether the programs impact girls differently than boys. Our analysis shows that, in fact, there were no differences between female and male students in either the improvement in standardized math test scores or Chinese test scores with either the CAL or OLPC programs. Our study suggests that among disadvantaged students in China’s rural areas and migrant communities, there is reason to believe that computer based learning can benefit both girls and boys equally. This finding has possible implications for China’s ongoing efforts to integrate computers and computing technologies into the nation’s underserved schools.
