Publication After-School Tutoring, Household Substitution and Student Achievement: Experimental Evidence from Rural China(2020-01-21) Behrman, Jere R.; Fan, C. Simon; Wei, Xiangdong; Zhang, Hongliang; Zhang, JunsenWorldwide children’s access to after-school learning activities is highly dependent on family backgrounds. Concern over the implications of such activities for child development and educational inequality has led to a global rise of public provision of after-school learning support. However little is known about interactions of public after-school activities and household investments in children’s learning. This paper contributes to the literature on the effects of public inputs on household inputs and student achievement in after-school settings. We build a model that integrates public and private inputs to produce student achievement through two competing mechanisms – diminishing returns to total inputs and complementarity between public and private inputs. When diminishing returns dominate complementarity, the model predicts the substitution away of private inputs due to increases in public inputs for all households, although the extent of crowding-out is smaller and therefore the test score gains are larger for children from disadvantaged family backgrounds facing higher costs of private inputs. We implement a randomized controlled after-school tutoring experiment in rural China where many children are left-behind by both parents and cared for by grandparents. During the program, tutees living with parents reported large and significant reductions in the amount of tutoring received at home, whereas tutees living apart from both parents reported much smaller, and often insignificant, reductions. We find that tutees’ math scores improved significantly, and more for children living without parents, although there is no evidence for improvement in tutees’ endline reading scores.Publication The Causal Effects of Parents' Schooling on Children's Schooling in Urban China(2020-01-21) Behrman, Jere R.; Hu, Yuan; Zhang, JunsenParental schooling is widely thought to improve child outcomes. But most studies on parental-child relations are associative, without control for estimation problems, such as unobserved intergenerationally-correlated endowments, if causality is of interest. The few exceptions are relatively recent studies that focus on high-income countries (HICs), with their much different contexts than the low- and middle-income countries (LMICs) in which the vast majority of children globally are growing up. This paper estimates the causal (conditional on the assumptions for the model) relationships between parents’ schooling and their children’s schooling in the most populous LMIC, using adult identical (monozygotic, MZ) twins data from urban China. Our ordinary least-squares estimates show that one-year increases in maternal and parental schooling are associated, respectively, with 0.4 and 0.5 more years of children’s schooling. However, if we control for genetic and other endowment effects by using within-MZ fixed effects, the results indicate that mothers’ and fathers’ schooling have no significant effects on children’s schooling. Our main results remain with various robustness checks, including controlling for measurement error. These results suggest that the positive associations between children’s and parents’ schooling in standard cross-sectional estimates in this major LMIC are mainly due to the correlation between parents’ unobserved endowments and their schooling and not the effects of their schooling per se.
