Eggs versus chewable vitamins: Which intervention can increase nutrition and test scores in rural China?

Despite growing wealth and a strengthening commitment from the government to provide quality education, a significant share of students across rural China still have inadequate access to micronutrient-rich regular diets. Such poor diets can lead to nutritional problems, such as iron-deficiency anemia, that can adversely affect attention and learning in school. Large scale policies in Northwestern China have attempted to tackle these nutritional problems using eggs. The overall goal of this paper is to assess the impact of the government's egg distribution program by comparing the effect on anemia rates of an intervention that gives students an egg per day versus an intervention that gives students a chewable vitamin per day. We will also assess whether either intervention leads to improved educational performance among students in poor areas of rural China. To meet this goal, we report on the results of a randomized controlled trial (RCT) involving over 2600 fourth grade students from 70 randomly-chosen elementary schools in 5 of the poorest counties in Gansu Province in China's poor Northwest region. The design called for random assignment of schools to one of two intervention groups, or a control group with no intervention. One intervention provided a daily chewable vitamin, including 5 mg of iron. The other mimicked the government policy by providing a daily egg. According to the findings of the paper, in the schools that received the chewable vitamins, hemoglobin (Hb) levels rose by more than 2 g/L (over 0.2 standard deviations). The standardized math test scores of students in these schools also improved significantly. In schools that received eggs, there was no significant effect on Hb levels or math test scores. Overall, these results should encourage China's Ministry of Education (MOE) to look beyond eggs when tackling nutritional problems related to anemia in an education setting.     

Class Size Effects on Student Achievement in Norway: Patterns and Explanations

The causal effect of class size on student performance is investigated using a maximum class size rule of 30 students to generate an instrument for actual class size. The data come from lower secondary schools in Norway, and the initial analysis reveals a small negative class size effect. Further investigations show that the effect varies among student subgroups and that the benefits of smaller classes are larger in schools with a high proportion of students who come from intact families. The second section of the paper uses information about the teachers' grading practices and the students' efforts in class to shed additional light on the revealed patterns of class size effects. Class size effects seem to be conditional on student effort.     

Do peer effects influence the academic performance of rural students at private migrant schools in China?

This paper examines peer effects on the academic performance of rural migrant students at both the class level and the individual level. The dataset is from a survey of more than 3000 students from all of the 87 migrant schools in Shanghai and Suzhou, China. The two-stage least squares method with an instrumental variable is employed to control for the endogeneity of peer performance variables. We found that peer effects exist among the migrant students at both class and individual levels. A one-point increase in the average of standardized math grade (SMG) of his/her classmates is associated with an increase of 0.5 points in the SMG of an individual (1.01 standard deviation). A one-point increase in a learning companion's SMG can result in an increase of 0.046 points in the student's SMG. The findings reveal that private migrant schools can improve rural migrant students' academic performance by optimizing students' class allocation and building study groups, providing an additional boost to the input-output efficiency of the human-capital education of the children of migrant workers in China, but the effects of these measures are limited.     

Compositional Effects,Segregation and Test Scores: Evidence From the National Assessment of Educational Progress

A model of the effects of economic level and ethnicity on grade 8 mathematics scores both within and between schools found that both the economic composition and the ethnic composition of a school were directly related to the effectiveness of that school. Projection of the data suggests that if the nation's schools were completely desegregated economically (but not at all ethnically), the test-score gap between free lunch students and students paying full price for lunch would decline by 25 %. Ethnic compositional effects for black, Asian/Pacific Islander (API), and Hispanic students were reversed from their within-school effects, with positive effects for students in schools with larger proportions of black and Hispanic students and a strong negative effect for students in schools with larger proportions of Asian/Pacific Islander students.     

Patrilineality,fertility, and women's income: Evidence from family lineage in China

This study investigates how traditional patrilineal family institution influences women's income through fertility behavior by offering evidence from family lineage (zongzu) in China. We hypothesize that family with strong lineage—proxied by owning genealogy—has a negative effect on women's income through the son-targeting fertility behavior. Using a difference-in-differences strategy, this study confirms the hypothesis. Relative to the women whose first child is a son, the women marring into families owning genealogy indeed have more children and lower income, if their first child is a daughter. In contrast, such finding does not hold for the male sample. Preliminary evidence suggests that shorter work time can explain the findings.

No longer left-behind: The impact of return migrant parents on children's performance

Using data from a rural household survey in China in 2009, we examine the impact of parental migration on children's educational outcomes. Consistent with the findings of a large empirical literature, we find that parental migration has a significantly negative impact on left-behind children's educational outcomes as measured by test scores in Chinese and math. But unlike much of the existing studies on the subject, we focus on the remediation effect of return migrant parents on once left-behind children's performance. This empirical strategy allows us to avoid the endogeneity issue concerning the migration decision that may have contaminated previous studies. We find evidence that return migrant parents help alleviate the harms caused by parental migration, and the remediation effect is stronger for children attending middle schools, and stronger for daughters. We also find suggestive evidence that return migrant parents improve children's performance through increases in after-school study time and education-related expenditures, following the return of migrant parents.     

Enrolment for degrees in agriculture and implications for agricultural development∗

The proportion of students who enrol for agricultural degrees at black universities??? is low, and only a few females enrol for these degrees. This has severe implications for agricultural development in the less developed areas. In order to increase enrolment for degrees in agriculture, it is suggested that improvements be made in the following: the society's image of agriculture, salaries of qualified agriculturalists, land tenure, vocational guidance at schools, quality of teaching of agriculture at schools, provision of bursaries and availability of jobs for agricultural graduates.     

Unequal school enrollment rights,rent yields gap,and increased inequality: The case of Shanghai

This paper first builds a simple theoretic model to explore how a special feature of enrollment policy of public primary schools in urban China, the unequal enrollment right between home owners and tenants, would produce rent-yields gap between different housings. The model also predicts that an enrollment policy featuring with tenant discrimination, accompanying with strict credit constraint, would reduce the chance of kids from middle-income families to attend better public schools while allow families with high initial wealth to access better high-quality public education at a lower cost. Using a hedonic pricing model, we find that, in Shanghai, rental yields of housings in neighborhoods associated with reputed public primary schools is on average 0.1–0.35 percentage-point lower than those associated with ordinary ones. We also explore how the rent-yields-gap varies across housing types, locations and changes over time. Nonetheless, our simulation computation suggests that the estimated opportunity cost of holding such schools in Shanghai is generally not a big amount and affordable for many families. Overall, the high entry costs of owing a housing is the major obstacle to access high-quality public primary education in urban China. These findings highlight how an education policy with features of inequality may contribute to education and residential segregation, and then reduce intergenerational mobility.     

Tracing value added in gross exports of China: Comparison with the USA,Japan, Korea,and India based on generalized LMDI

This study first traces value added in gross exports of China during 2000–2014 to four components, namely domestic value added absorbed abroad (DVA), domestic value added return home (RDV), foreign value added (FVA), and pure double-counted terms (PDC), then compares these four components in China's exports with those in exports of the USA, Japan, Korea, and India. Second, this paper proposes a generalized logarithmic mean Divisia index (GLMDI) method and combines additive and multiplicative decomposition to decompose DVA gaps between China and the other four countries into value added coefficient effect, input-output structure effect, domestic scale effect and foreign scale effect. The aggregate value added coefficient effect is then attributed to sectoral level. Results show that DVA always occupied the largest share in the gross exports of China, which ranged from 74.60–82.84% during 2000–2014. Before 2011, DVA share of China's exports was generally the second smallest among five countries; since 2011, DVA share of China's exports increased, and China had the largest DVA share in 2014 (81.39%). Sectors having a large FVA share in China's exports usually had a large DVA share, such as “Mining” (MIN), “Computers, Electronic and Optical” (CEO), and “Basic Metals” (BAS). Additive and multiplicative decomposition analyses indicate that value added coefficients had a negative and increased effect on DVA gaps between China and the other four countries. Attribution analysis revealed that CEO sector had the largest negative value added coefficient effect in comparison between China and the USA, Japan, and Korea and its effect increased in comparison between China and the other four countries. Policy implications derived are finally discussed.     

Migrate for education: An unintended effect of school district combination in rural China

A large number of village primary schools in rural China were closed since the 1990s. This paper studies the impact of the reduction in the number of primary schools on the migration decision of rural residents. First, using China Health and Nutrition Survey that contains information on community characteristics, we find that both the disappearance of village primary school and the increased distance to nearby primary school increased the migration probability of village residents. Second, using the 1% population survey in 2005 and prefecture level information, we find that the decline in the number of primary schools between 2000 and 2004 increased the migration probability of rural residents. Exploring the heterogeneous effects, we find that the migration of individuals with primary-school-age children is more sensitive to the relocation of primary schools, and that the effect is stronger for families with boys than those with girls. These results suggest that human capital investment motive and regional education policy play an important role in China's urbanization process.

From Villages to Urban Neighborhoods: Urbanization and Health

With rapid urbanization, millions of rural villagers have become urban citizens in China. This paper estimates the effect of the in situ urbanization policy on an individual's health by employing the difference-in-differences framework and using panel survey data from the China Family Panel Studies. Our findings show that this program, unlike other kinds of urbanization, which have had negative impacts on mental health or made people smoke or drink more, increased people's self-reported health status significantly. Further mechanism analysis reveals that the in situ urbanization policy affected health by increasing people's confidence in the future, their satisfaction with their current lives, and their medical insurance enrollment. This study highlights the importance of “the city comes to villagers” urbanization in China, and it can play an essential role in advancing the urbanization rate and avoiding the negative impacts of urbanization on health.     

Effect of Migration on Children＇s Self-esteem in Rural China

China＇s rapid economic growth has been facilitated by its large volume of rural to urban migration. China ＇s projected future development, especially increasing urbanization, implies that such migration will further intensify. However, migration does not come without cost. There are concerns about the potential negative impacts of migration on children＇s care, education, and, in particular, the self-esteem of children left behind in villages where one or both parents have out-migrated to cities. In this paper, we employ unique survey data collected from Shaanxi Province, where more than 4700 ninth grade students from 36 rural junior high schools in five counties were surveyed in late 2011. The results show that having both parents migrate into cities significantly reduced children ＂s self-esteem. The effects are also gender sensitive. Girls that had a father or both parents who had out-migrated were inclined to have lower self-esteem than boys. Moreover, our study findings indicate that parental migration decreased children ＂s self-esteem more for individuals with initial low self-esteem.     

Exposure to socially influential peer parents: Evidence from cadre parents in China

Parents with a special social status generate spillover effects to other parents and children. Because cadres (government officials) in China have a broad influence on resource allocation, their presence elicits responses from surrounding parents and students. Exploiting random classroom assignments in Chinese middle schools, we find that increased exposure to classmates' cadre parents raises parents' attention to their children's friendships and guidance over schoolwork. We also find evidence suggesting that parental changes raise the child's test scores. The findings highlight parental adjustments as a mediator of the external influence of peer parents on children.     

Does parental migration impede the development of the cooperative preferences in their left-behind children? Evidence from a large-scale field experiment in China

In human capital theory, noncognitive abilities play an essential role in individual and societal success. Parents' migration for work purposes may inhibit the development of children's noncognitive abilities, but its influence on children's cooperation preferences remains unclear. Using three one-shot public goods games, we examine the impacts of parental migration on the development of children's cooperation preferences and whether introducing punishment mechanisms could partly exacerbate or offset the effects. We conducted a large-scale field experiment with more than 1600 rural students aged 6–16. Our main findings are as follows. First, the cooperation level of non-left-behind children increases significantly with age, while being left behind may affect this stable development track. Specifically, we find that paternal migration significantly decreases children's cooperation levels, while maternal or both parents' migration does not. Second, punishment mechanisms can significantly promote children's cooperation levels and offset the negative effect of paternal migration. Exogenous punishments work across ages, while endogenous punishments work only among middle school students. However, as the extent to which children were left-behind deepens, the offsetting effects of the punishment mechanisms gradually weaken.     

Effects of Japanese compulsory educational reforms on household educational expenditure

This study investigates the effects of the 2002 Japanese reforms of compulsory education on household expenditure on supplementary schooling and out-of-school activities for junior high school students. These reforms marked a dramatic change in Japan's compulsory education system in two main respects: from April 2002, every Saturday became a public school holiday and instructional time was reduced following the government's revisions of national curriculum guidelines, leaving private schools largely unaffected. Based on aggregate data taken from the Child Study Expenditure Survey, the difference-in-differences estimation—households with children attending public schools as the treatment group and those attending private schools as the control group—reveals that the 2002 educational reforms increased target household expenditure on supplementary education by 13% and spending on outdoor activities/volunteering, arts, sports, and cultural activities by 23%. Disaggregated analysis based on microdata taken from the National Survey of Family Income and Expenditure carried out by the Bureau of Statistics further reveals that the impacts of these educational reforms were larger for higher-income households than for lower-income ones.     

The comparative performance of chartered accountancy students in South Africa: The impact of historical legacies

African students continue to underperform in South Africa's schools and universities. This paper investigates the comparative performance of African chartered accountancy students from school to post-university level. The paper employed a mixed-method approach to analyse a series of cross-sectional datasets. The results showed that African students have underperformed at school, university and at post-university level, although the performance gap appears to be narrowing in the first professional chartered accountancy examination. The differential performance of these students was explained by poorer marks in mathematics and English that can be traced back to historical legacies in the education sector. South African universities, moreover, perpetuate this disadvantage because they have retained Eurocentric teaching approaches. In order to remove these barriers, tuition at school and university must be complemented by cross-cultural teaching practices and bridging programmes.     

Economic policy uncertainty and firm’s cash holding in China: The key role of asset reversibility

This paper investigates how asset reversibility affects the sensitivity of firm’s cash holding to economic policy uncertainty in China. Using the 2012 national input-output table for 139 industries, we measure the industry-level asset reversibility and match them with nonfinancial publicly listed firms over 2007−2017. The results show that asset reversibility has a significant and negative effect on the positive uncertainty-cash holding sensitivity, especially for firms with more severe financial constraints. Furthermore, we find that firms with higher asset reversibility invest more in fixed assets, suggesting that real investment is an important mechanism. In addition, baseline results are robust to potential endogeneity and alternative measures of asset reversibility and economic policy uncertainty. Our findings reveal that asset market friction is a critical determinant of firm’s cash holding.     

Does a name change attract better students? Evidence from Chinese universities

A number of Chinese universities have changed their names in recent years, providing an opportunity for an empirical analysis of whether a name change could attract students with higher admission scores. Using panel data from 522 universities in China (2005 to 2015), this paper examines the effect of a university's name change on student admission scores. The results indicate that, in general, a name change did not significantly improve the admission score of the university. However, after examining four types of name changes it was found that different name change methods had different effects. Specifically, renaming an institution from a college to a university and incorporating the name of a large regional area lead to a significant improvement in the admission scores; in contrast, choosing a more “fashionable” name and eliminating references to historical industrial affiliations have no significant effect, and may even have a negative impact.
