Impacts of publicly funded health insurance for adults on children's academic achievement

Publicly funded adult health insurance through the Affordable Care Act (ACA) has had positive effects on low-income adults. We examine whether the ACA's Medicaid expansions influenced child development and family functioning in low-income households. We use a difference-in-differences framework that exploits cross-state policy variation and focus on children in low-income families from a nationally representative, longitudinal sample followed from kindergarten to fifth grade. The ACA Medicaid expansions improved children's reading test scores by ~2% (0.04 SD). Potential mechanisms for these effects within families are more time spent reading at home, less parental help with homework, and eating dinner together. We find no effects for children's math test scores or socioemotional skill development.     

Is care by grandparents or parents better for children's non-cognitive skills? Evidence on locus of control from China

This study investigates the effect of grandparental involvement in childcare on children's locus of control (LOC), which is an important non-cognitive skill that affects children's future development. We use data from the China Family Panel Studies, which is a nationally representative survey, and employ instrumental variables to address the endogeneity of family childcare choice. We find that children with grandparental care have more external LOC than children in the sole care of their parents do; that is, they are more likely to attribute individual success to external factors, such as luck, fate, and family background. This finding is robust to different measures of grandparental involvement in childcare and different model specifications, as well as a minor violation of the exclusion restriction of the instruments. We further examine the potential mechanisms underlying this effect. Grandparents have more external LOC than parents do, which can affect children's LOC through intergenerational transmission of LOC. Their parenting attitudes and styles are also different from parents' in that grandparents take less responsibility for children's academic performance than parents do and are less strict with children. In addition, grandparental care induces adverse effects on children's family environment.     

One-child policy and childhood obesity

This paper investigates the effect of only children on childhood obesity in China. We use implementation measures of family planning policies as instrumental variables in the estimations, and find that being raised in a one-child family significantly increases the weight, body mass index, and probability of being overweight or obese for children. By examining mothers' care-taking behaviors and their children's dietary habits and nutritional intake, we identify the following channels linking one-child families with childhood obesity. (a) In one-child families, parents prefer spending money to using their time to care for their children. (b) In one-child families, children eat more high-sugar, high-fat, and high-protein food. A time–money trade-off could be a plausible mechanism of the effects we document.     

家庭规模、子女状况与农民工幸福感

为了考察农民工家庭规模、幸福感的关系,以及子女状况在其中的作用,基于2021年中国综合社会调查（CGSS）的微观数据进行实证分析。结果显示,家庭规模、子女状况、幸福感之间存在两两正相关关系;子女状况在家庭规模与幸福感之间起部分中介作用。因此,提高农民工幸福感可以从扩大农民工家庭规模,支持农民工家庭子女数量增加的角度入手,也为减轻社会老龄化造成的负担提供了有力支持。     

Causal effects of family income on educational investment and child outcomes: Evidence from a policy reform in Japan

The Child Allowance Policy (CAP) in Japan, a nationwide cash transfer program for families with children, was designed to increase household expenditures toward children. Using unforeseen changes in the CAP that occurred due to the electoral results as a source of exogenous variation in income in the early 2010s, this paper examines the causal impact of family income on households’ private educational expenditures and child outcomes in the short-run, based on a longitudinal parent-child survey. The ordinary least squares (OLS) and first-differenced (FD) results show that family income is in most cases positively correlated with child's cognitive outcomes, and, to a lesser extent, with families’ educational expenditure on their children. Based on the FD instrumental variable (FD-IV) estimation, using unexpected changes in CAP payments as an instrument, we find positive income effects on educational expenditure in the short-run. However, we did not find statistically significant impacts on children's cognitive outcomes.     

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.     

Like father,like son? Parental input,access to higher education,and social mobility in China

This paper studies the role of parental input in university access in the context of a 10-fold expansion of China's higher-education sector since 1999. Using a Logit regression, we find that an increase in a parent's education level significantly raises their child's probability of entering university. Moreover, the effects of parental involvement and children's trust towards their parents on university entrance are highly significant. The results are robust to Probit and Linear-Probability-Model specifications. Heterogeneity analysis reveals that for rural and/or worse-educated families, parental involvement significantly affects the child's access to university, while for urban and/or better-educated families, the child's own study attitude is key for progression to university. To address the confounder of genetic inheritance, we use regression discontinuity and two-stage least squares and find that the nine-year compulsory education policy launched in 1986 not only increased the education years of the first generation by about 1.66 years, but has also had a lasting effect by raising the second generation's probability of access to university by 11.77%.     

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.     

The effect of family size on parents' labor supply and occupational prestige: Evidence from Taiwan and Mainland China

This paper studies the effect of family size on parents' labor supply and occupational prestige, using the censuses of both Taiwan and Mainland China. We rely on the exogenous increase in child quantity that results from having twins at the first birth. Our results indicate that an increase in family size has negative effects on the labor supply of mothers but not of fathers, in both Taiwan and Mainland China. In addition, we find that in Taiwan fathers tend to switch to occupations with lower prestige scores in response to an increase in family size. However, the negative effect of family size on occupational prestige is not observed in Mainland China, where the occupational mobility is low.     

Decomposing the rich dad effect on income inequality using instrumental variable quantile regression

In this paper we evaluate the relative importance of the two main channels, namely the composition effect and the income structure effect, through which the paternal income affects children's income inequality. Using data on 2677 pairs of father and children from China Health and Nutrition Survey (CHNS), we construct the counterfactual income of children from poor families if they had the same characteristics as children from rich families. We propose an instrumental variable quantile regression-based method to solve the endogeneity problem and decompose the rich dad effect on income inequality into the composition effect and the income structure effect. We find that the composition effect explains at least 80% of the income difference at any quantile, and it explains all the income difference at the top four deciles. Income structure effect has a significant impact only at quantiles between 20% and 40%, where it explains about 20% of the income difference.     

DOES MOTHER'S EDUCATION MATTER IN CHILD'S HEALTH? EVIDENCE FROM SOUTH AFRICA1

Using the 1993 South Africa Integrated Household Survey, this paper studies the effect that mother's education through the knowledge channel has on children's health using height for age Z‐scores as health measure. Under a two‐stage least square methodology we find that an increase in 4 years on mother's education (approximately 1 standard deviation) will lead to an increase of 0.6 standard deviations on her child's height for age Z‐score. We also find, as the medical literature suggests, support for the hypothesis that mother's education is more important for children older than 24 months of age.     

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.     

The impact of education on income inequality and intergenerational mobility

This paper analyses the effects of innate ability, compulsory education (grades 1–9), and non-compulsory education (grades 10–12 and higher education) on inequality and intergenerational mobility of income, by constructing a four-period overlapping-generation model. We find that innate ability and family investment in early education play important roles in explaining income inequality and intergenerational income mobility. Though children from the wealthiest families are only 1.36 times ‘smarter’ that those from the poorest, the gap in human capital expands to 2.35 at the end of compulsory education and to 2.89 at the end of non-compulsory education. One important reason for the increase is that poor families invest relatively less in children's early education than do wealthy families; therefore, their children attend lower-quality schools, which results in them being much less likely to participate in higher education. By simulating policy experiments for different types of government education expenditure, we find that direct subsidies to poor parents are the most efficient and effective policy for mitigating poor families' budget constraints with regard to early-education investment in their children.     

Children's marriage and parental subjective well-being: Evidence from China

The marriage of children is a milestone event in parenthood, while how parents' well-being evolves around the time children get married is limitedly understood. This paper examines the relationship between children's marriage and parents' subjective well-being. Using China Family Panel Studies (CFPS) data, we find that parental subjective well-being is positively associated with children's marriage. An examination of the underlying mechanisms shows that, first, children's marriage can significantly enhance parents' sense of security in old-age care and their confidence in the future. Second, the older the unmarried children are, the more anxious the parents who hold stronger traditional ideology will be. Third, parents will increase their consumption expenditure after their children get married; and compared with daughters, sons' marriages have a stronger effect on parental well-being. These findings reveal that parental economic pressure due to China's biased sex ratio and marriage squeeze is relieved after their children's marriage.     

Mobile Payment and Informal Business: Evidence from China's Household Panel Data

This paper uses household panel data to explore the impact of mobile payments on China's household business activity. Using a difference‐in‐difference fixed effect specification, I find that mobile payment users are more likely to operate small‐scale and self‐employed informal businesses. The impact of using mobile payment primarily derives from the transition of agricultural families to business owners and the development of informal businesses. The paper illustrates an associated increase in employment and income for family members, with more pronounced effects on low‐income and rural households. It also provides prima facie evidence of the increase in fund transfers, which is important for risk sharing that informal businesses may encounter.     

Human capital investment in children: An empirical study of household child education expenditure in China, 2007 and 2011

Household education expenditure is an important component of human capital investment in children. In China, the rising child education expenditure and the subsequent financial burden on families have attracted much research and policy attention in the recent years. Using 2007 and 2011 data from the Urban Household Education Surveys, our empirical study provides new evidence on the education expenditure level, ratio of expenditure to household income, and inequality in this expenditure. We also elucidate changes in China's household education expenditure and explore factors associated with such changes. From the analysis, we obtain the following findings. First, education expenditure incurred outside the school significantly contributes to increasing household education expenditure. Second, compulsory education programs are effective in curbing in-school education expenditure; however, it does not prevent the rapidly increasing education investment outside school. Third, education expenditure disproportionally increases with family income. In other words, a larger share of the income earned by lower income families is spent on children's education, compared to higher income families.     

Did children's education matter? Family migration as a mechanism of human capital investment: evidence from nineteenth‐century Bohemia

This article analyses the rural–urban migration of families in the Bohemian region of Pilsen in 1900. Using a new 1,300‐family dataset from the 1900 population census, the role of children's education in rural–urban migration is examined. The findings indicate that families migrated to the city such that the educational attainment of their children would be maximized, and that there is a positive correlation between family migration and children being apprentices in urban areas. The results suggest that rural–urban migration was powered not only by the exploitation of rural–urban wage gaps but also by aspirations to engage in human capital investment.     

Educational Investment for Future Marriage? Evidence of Missing Girls from China

Numerous studies have shown that a sex ratio imbalance (more boys than girls in a society) may result in a sequence of social problems. This study investigated the expected effect of a high sex ratio on educational investment. Using nationally representative data from the China Family Panel Studies and the 2010 Census, we determined the following: (i) a high sex ratio increased educational expenditure for boys relative to girls; (ii) parents who took education seriously and who cared about their children's education were more likely to invest in education to appear attractive in the future marriage market, and (iii) the profound impact of a high sex ratio on educational expenditure was more pronounced in less educated and poorer families. Our findings raised the possibility that the effect of the sex ratio may bring about more gender inequality in the future. The implicit cost of a high sex ratio may further lead to a vicious cycle of family fertility and childbearing.     

Does the early bird catch the worm? Evidence and interpretation on the long-term impact of school entry age in China

The long-term impact of children's age at primary school entry on educational attainment and labor market outcomes is one of the primary concerns to families, educators, and policymakers. Using a nationally representative survey of families and individuals, this paper is among the first to explore these effects in a causal sense in the Chinese context and understand the underlying mechanisms. We use a regression discontinuity (RD) design that employs the threshold date for primary school entry set by the 1986 Compulsory Education Law of China as a source of exogenous variation in the timing of school entry. We first document a salient and robust compliance rate of school entry requirement. RD estimates indicate that being born right after the cutoff date significantly increases years of schooling and annual earnings for non-agricultural jobs for the full sample. We also observe remarkable heterogeneous effects on labor market performance by gender. Being born right after the cutoff increases the probability of being in the labor force for men, but decreases that for women. We find that the decline in female labor force participation is mainly driven by women who come from economically and socially disadvantaged families. Further evidence suggests that this decline can be explained by supply-side factors including fertility decision and childcare provisions.     

When left-behind children become adults and parents: The long-term human capital consequences of parental absence in China

This study examines the long-term effects of childhood left-behind experience on human capital outcomes across two generations in China. Using data from the China Family Panel Studies (CFPS), we find evidence that adults with left-behind experience in early life have fewer schooling years, lower cognitive test scores, a lower Big Five personality traits index, but a higher internal locus of control. Meanwhile, they are more likely to report underweight, chronic diseases, depression, and lower levels of perceived health and happiness. Our findings of the negative consequences on personality traits and health outcomes are robust to a battery of specification and validity tests. These effects also differ markedly by adults' gender, birth cohort, hukou status, and the characteristics of left-behind experience (i.e., type, timing, and duration). Further, our results also suggest a potential intergenerational transmission mechanism in which human capital loss is induced by one's early-life exposure to parental absence. Specifically, one's childhood left-behind experience is also inversely associated with their offspring's outcomes such as Big Five noncognitive skills, birth weight, and height-for-age z-score. Although adults with left-behind experience are inclined to spend more time with offspring compared with their non-left-behind counterparts, they also tend to have significantly poorer household socioeconomic outcomes and less offspring educational investment.
