Peer effects among graduate students: Evidence from China

This paper examines peer effects among graduate students in a Chinese university. We implement a quasi-experiment empirical strategy and find that a student's master GPA is positively associated with his roommates' college GPA. Our results exclude the possibilities that the peer effects are driven by the spillover of peer intelligence or effort level but support the academic skill mechanism.     

Large-scale school meal programs and student health: Evidence from rural China

Reducing urban-rural gaps in child health is one of the most difficult challenges faced by many countries. This paper evaluates the impact of a large-scale school meal program in rural China on the health and nutritional status of students aged 6–16 in compulsory education. We use data from the China Health and Nutrition Survey corresponding to four pre-treatment years (2004, 2006, 2009, and 2011) and one post-treatment year (2015) and find that program participation is, on average, associated with a higher child height-for-age. The impacts are larger among students in a better health condition but small or not significant among the most disadvantaged. We do not observe heterogeneous effects across several individual and household characteristics. We also find positive but not significant effects on Body Mass Index-for-age and weight-for-age. The results suggest that NIP partially improved students' health over the first years of implementation, but more support is needed to achieve broader impacts that effectively reach all vulnerable students.     

Peer effects in rural housing demand: Evidence from China

This paper utilizes data from the China Household Finance Survey 2011 to study peer effects in housing demand in rural China. We find that focal households' housing consumption is heavily influenced by peer households' housing consumption. Evidence from placebo tests, IV estimates and robust tests suggests that the relationship is causal. In addition, we show that status seeking and social learning play important roles in determining peer effects in the demand for rural houses. Finally, we explore the heterogeneity in peer effects and determine that the leading mechanism is status seeking.     

The impact of agricultural technology adoption on income inequality in rural China: Evidence from southern Yunnan Province

This study analyzes the impact on income inequality of government efforts to increase agricultural incomes in rural China. It collects and analyzes survey data from 473 households in Yunnan, China in 2004. In particular, it investigates the effects of government efforts to promote improved upland rice technologies. Our analysis shows that farmers who adopted these technologies had incomes approximately 15% higher than non-adopters. Despite this relatively large increase, we estimate that the impact on income inequality was relatively slight. This is primarily due to the fact that lower-income farmers adopted the improved rice technology at rates that were roughly equivalent to those of higher-income farmers.     

Returns to education in China: Evidence from the great higher education expansion

China experienced a near 5-fold increase in annual Higher Education (HE) enrolment in the decade starting in 1999. Using the China Household Finance Survey, we show that the Great HE Expansion has exacerbated a large pre-existing urban-rural gap in educational attainment underpinned by the hukou (household registration) system. We instrument the years of schooling with the interaction between urban hukou status during childhood and the timing of the expansion – in essence a difference-in-differences estimator using rural students to control for common time trends. We find that the Great HE raised earnings by 17% for men and 12% for women respectively, allowing for county fixed-effects. These Two Stage Least Squares (2SLS) estimates, which are robust to additional controls for hukou status at birth fully interacted with birth hukou province, can be interpreted as the Local Average Treatment Effect (LATE) of education on earnings for urban students who enrolled in HE only because of the Great HE Expansion. For the selected subsample of respondents with parental education information, we find that the 2SLS returns for students from more disadvantaged backgrounds are at least as high as their more advantaged counterparts, for both genders.     

Export expansion and intergenerational education mobility: Evidence from China

This paper investigates the impact of China's export expansion during 2000–2007 on the local intergenerational education mobility. We construct prefecture-level export shocks, by exploiting variations in national cross-industry export changes and cross-prefecture industrial employment. Empirical results suggest that prefectures experiencing larger export shocks are more likely to have higher intergenerational education mobility. The baseline results stand when we use alternative measures for educational outcomes, consider the migration situations, or include more controls. Using the intergenerational mobility framework proposed by Becker et al. (2018), we explain and empirically test how income effect and substitution effect of export expansions influence education mobility. The mechanism testing suggests that the income effect is the dominant force underlying the results.     

The effect of education expansion on intergenerational transmission of education: Evidence from China

More than 70 million people have attained a tertiary education due to China's higher education expansion (CHEE). Using data from the Chinese Household Income Project Survey, we examine how dose education expansion have an effect on the intergenerational transmission of education (ITE) by using the exogenous surge brought by CHEE. Our finding is that, after carefully addressing the interference induced by the Compulsory Education Laws and the selection bias caused by intergenerational co-residence, CHEE reduces ITE when educational achievement is measured by schooling years. However, when taking the quality of higher education into account, we find that CHEE does not have a significant effect on ITE, which suggests that the intergenerational inequality in higher education remains. Moreover, we identify the mechanism that the inequality in the quality of high school education extends to tertiary education to explains our findings. To account for the mixed findings in previous literatures, we further propose a general framework for understanding the effect of education expansion on ITE.     

Returns to military service in off-farm wage employment: Evidence from rural China

This paper studies the returns to military service in off-farm wage employment and the implications of military service on the rural-urban transition in rural China. We exploit government-induced variations in aggregate enrollment rates as our instrumental variable. Using data from the China Family Panel Studies, we find a substantial positive effect of military service on off-farm wage employment and earnings for men of rural origin, which is comparable in magnitude to the estimated returns to a college education in China. We also provide evidence that the earnings premium is likely to be explained by improved access to urban formal employment, political and human capital accumulation. However, in spite of the off-farm employment gain for all cohorts, we find that the positive earnings premium of military service is mainly concentrated among the pre-1970 cohort.     

Effects of school closure on household labor supply: Evidence from rural China

This paper studies the effects of school closure on household labor supply exploiting China's large-scale rural primary school closing during the early 2000s. Using CHNS 1991–2011 and CHIP 2007–2008 datasets and a difference-in-differences approach, we find that school closure significantly increases the total annual income of mothers of primary school-aged children, which comes virtually entirely from increases in wage income, due to more participation, more working hours, and higher wage rates. This significant positive effect can plausibly be attributed to their migration responses: mothers engage in temporary rural-urban migration to care for children following school closure. We find no effects on fathers' income and migration behavior. Our study provides the first causal estimation of the impacts of school closure on household labor supply and sheds light on the migration decision-making of rural females.     

Farm technology and technical efficiency: Evidence from four regions in China

In this paper we fit stochastic frontier production functions to data of Chinese farms grouped into each of four regions—North, Northeast, East, and Southwest—over 1995–1999. These frontier production functions are shown to have statistically different structures, and the elasticities provide some evidence of diminished marginal products of chemical inputs in the East and capital services in the North and Southwest. Labor has a low elasticity except in the North. Standardized technical efficiency scores are estimated for the farms and are shown to have the same structure across regions and to be related to the age of the household head, land fragmentation, and the village migration ratio, controlling for year effects and village or regional fixed effects.     

Access to credit and farmland rental market participation: Evidence from rural China

In this study, we analyze the impact of access to credit on farmland rental market participation of rural households. The study uses a nationally representative survey data of China Family Panel Studies and an endogenous switching probit model that accounts for selection bias for both observed and unobserved factors. Findings reveal that access to credit stimulates farmers' decisions to participate in farmland rental markets by increasing the likelihood of renting in and renting out farmland by about 10% and 20%, respectively. Results also reveal that the impact of access to credit on farmland rental market participation is heterogeneous when it comes to the age of the operator and and geographic locations of farmers. We show that younger credit users have a higher probability of renting in farmland, while their older counterparts have a higher probability of renting out farmland. Besides, credit users residing in central China have a higher probability of renting in farmland, while those living in eastern China have a higher likelihood of renting out farmland. Our findings highlight the importance of improving farmers' access to credit in facilitating the development of rural farmland rental markets.     

Inequality of opportunity and household education expenditures: Evidence from panel data in China

This paper offers one of the first pieces of empirical evidence on the impact of inequality of opportunity on household education investment by using the panel data from China Family Panel Studies (CFPS) in three waves (2010, 2012 and 2014). Our result suggests that inequality of opportunity has a negative effect on household education expenditures. This result is robust to a series of robustness checks. Furthermore, for relatively disadvantaged households (household heads with less education, income, or rural hukou status), inequality of opportunity has a larger negative effect on their education expenditures. Policy suggestions to lower inequality of opportunity may include reducing labor market discrimination based on gender and hukou status, balancing education resources to create more equal educational opportunities, and offering children education subsidies in low-income families.     

Impact of urban-rural health insurance integration on health care: Evidence from rural China

In recent years, Chinese local governments have experimented with integrating the social health insurance system segmented between rural and urban areas to unify the administration, policy, and funds of various health insurance programs. In this study, we take advantage of the staggered implementation of the urban-rural health insurance integration across cities over time to examine the impacts of the integration on rural residents' health care utilization and health outcomes. Based on an original city-year level policy dataset and the China Health and Retirement Longitudinal Study (CHARLS) for the years 2011, 2013, and 2015, we find that the integration significantly increases the middle-aged and older rural residents' inpatient care utilization and this positive effect is particularly salient in poor areas. Moreover, we find that the positive policy effect of integration is attributed to enhanced health insurance benefits, such as a higher reimbursement rate for inpatient care. However, the integration has limited impacts on the middle-aged and older rural residents' health outcomes. This study reveals the partial success of urban-rural health insurance integration to reduce health care inequality in China.     

Intergenerational transmission of education: The case of rural China

The intergenerational transmission of education has received considerable attention in recent empirical research in many countries. However, the research on intergenerational transmission of education in China is still relatively rare. This paper investigates the impact of parental schooling on their children's schooling in rural China using the data collected by the authors themselves. Our results show that (i) the intergenerational transmission of education in rural China is not as high as those have been reported in the literature for several other countries;(ii) There exists significant transmission effect of education in the subgroup born after the 1980s, but not for those who were born in the year of 1980 onward. The results also stand up to several different tests and robustness checks. Our findings suggest that promoting the equal education opportunity and investing in children of disadvantaged group will have long-term effects for the accumulation of human capital. China can promote increasing gains for its acquisition of human capital, and tap into this foundation for sustainable growth and development in the future.     

The effect of internet usage on perceptions of social fairness: Evidence from rural China

Using Chinese Social Survey data for 6205 geographically distributed rural households, this paper assesses the impact of Internet usage on social fairness perceptions (SFPs) among Chinese farmers. To address the potential selection bias associated with voluntary Internet usage, the analysis employs an endogenous ordered probit model whose results suggest that, in general, Internet usage has a statistically significant and negative impact on farmer SFPs. Nonetheless, an additional disaggregated analysis reveals that this impact is heterogeneous among different age groups and geographic regions, as well as between male and female household heads.     

The impact of technology identification policy on firm innovation: Evidence from China

Using firm-level data of companies listed on China's A-share market from 2006 to 2017, this research applies a difference-in-differences (DID) empirical method to test whether the state policy in China used for identifying firms as being “high-tech” enhances their innovative capabilities. This paper presents three main findings. First, multiple robustness tests confirm that the state technology identification policy does improve the total number of patent applications as well as the number of patent invention applications. Second, government subsidy is an important channel through which this policy affects a firm's innovation capabilities. Third, this policy has a more prominent and positive influence on the innovation capabilities of firms located in regions where there exist a higher rate of taxation in addition and relatively more developed products and factor markets. Fourth, we conduct a flexible back-of-the-envelope cost-benefit analysis to demonstrate that the high-tech firm identification policy does improve the overall level of social welfare. The empirical results of this paper have far-reaching implications for China's innovation policies.     

Labor allocation in transition: Evidence from Chinese rural households

Empirical models are developed in this paper to quantitatively analyze households' participation in decisions on hiring labor and supplying labor off the farm, hired labor demand and off-farm labor supply of rural Chinese households. Econometric estimates use micro-level data from Zhejiang province over the period 1995–2002. The main results suggest that the decisions to hire labor and participate off the farm are made jointly and are positively correlated. A household's labor demand decreases with increasing wages for hired labor, whereas the effect of the wages of off-farm workers on a household's labor supply differs significantly depending on the household's kind of labor market participation. The results also indicate that the accumulation of productive assets, the development of livestock production and agricultural prices have increasing effects on labor demand but reducing effects on a household's off-farm labor supply. Land market integration enhances participation significantly but has no significant impact on time allocation. Finally, the results suggest non-separability between hired labor demand and household characteristics, indicating the rural labor market in Zhejiang province is still functioning imperfectly.     

The social support returns to college education in China: Evidence from online medical crowdfunding

Attaining a college education bestows advantages in the labor market, but it is undetermined whether a college education could also benefit those in need of assistance. Using a unique dataset from a large online medical crowdfunding platform based in China, this paper investigates the social support returns to college education. Our study finds that patients attaining college education would raise 88.1% more funds through medical crowdfunding. A variety of identification strategies suggest that the relationship is causal. By examining the potential mechanism, we conclude that college-educated patients have more detailed narratives and have more school-related social connections who are willing to verify and distribute the campaigns, attracting more supporters and ultimately raising more funds.     

Skill complementarities and returns to higher education: Evidence from college enrollment expansion in China

We find that the increased supply of college graduates resulting from college enrollment expansion in China increases college premiums for older cohorts and decreases college premiums for younger cohorts. This finding is inconsistent with the canonical model that assumes substitution among workers of different ages. We subsequently build a simple model that considers complementarities among workers of different ages and different skill levels. Our model predicts that the college premium of senior workers increases with the supply of young college graduates when skill is a scarce resource. The model's predictions are supported by empirical tests.     

The productivity impacts of energy efficiency programs in developing countries: Evidence from iron and steel firms in China

We study the impact of a national energy efficiency program on total factor productivity (TFP) growth in firms in China's iron and steel industry. Using detailed firm-level survey data and multiple approaches to estimate program effects, we find participating firms experienced greater annualized TFP change. Our base specification estimates the program increased annual TFP growth by 3.1 percentage points, implying an annual private benefit of 148.7 million RMB/year per firm, with approximately equal contributions from technical change and scale efficiency change. Our results suggest that firms undervalued energy efficiency investments prior to the start of the program.
