Stereotypes, Role Models, and the Formation of Beliefs (submitted)

(shortened from the previous title of "Role Models, Girls' Math Ability, and the Formation of Beliefs: Evidence from Random Assignment of Students in Chinese Middle Schools")

Abstract

Stereotypes can erroneously reduce children's beliefs about their own ability, negatively affecting effort in school and investment in skills. Because of dynamic complementarity in the formation of human capital, this may lead to large negative effects on later life outcomes. In this paper, we show evidence that role models, in the form of female math teachers, can counter the negative effects of gender-based stereotypes on girls' perceptions of their math ability. A simple model of investment in human capital under uncertainty predicts the greatest effects of role models accruing to girls who perceive themselves to be of low ability. We exploit random assignment of students to classes in Chinese middle schools to test this prediction, examining the effects of teacher-student gender match on students’ perceived ability, aspirations, investment, and academic performance. We find that, for girls who perceive themselves to be of low ability, being assigned a female math teacher causes large gains in all of these outcomes. We see no effects of teacher-student gender match on children who do not perceive themselves to be of low math ability. We show evidence against the potential alternative explanations that differential teacher effort, skill, teaching methods, or differential attention to girls drive these effects.

 

 

The Power of Credential Length Policy: Schooling Decisions and Returns in Modern China (submitted)

with Feng Hu

(note: this paper was previously circulated under the title "The Importance of Educational Credentials: Schooling Decisions and Returns in Modern China")

Abstract:

Every government chooses the length of educational credentials. We study a policy change in China which increased the length of primary school by one year but did not change the primary school curriculum. This change increased total years of schooling by one for most affected individuals and raised monthly income on average by two percent. The policy is progressive, bringing higher income returns (5-7%) for the least educated. We estimate the policy has reallocated 900 billion person-hours from labor to education to date and generate cost-benefit estimates to quantify this tradeoff, highlighting the public finance implications of credential length policy.

Private School Entry and Girls’ Schooling Outcomes in Rural India

with Andrew Foster

Abstract:

Private primary and secondary schools are an increasingly central part of many education systems in the developing world, particularly in South Asia. A prominent criticism of this development is that the cost of private school induces poor families to pull some children out of school in order to afford fees for the others, and that girl children are the most likely to suffer as a result. We test this hypothesis using panel data from a representative sample of Indian villages spanning 1970 to 2015. We find that boys benefit disproportionately from private schools: in villages where private schools establish, the average schooling of boys increases by approximately one year while girls’ schooling stays constant. We find no evidence, however, for the claim that girls’ schooling decreases after private school entry. In addition, we find that average years of completed schooling increases by 0.8 years for girls whose older brothers are exposed to private schooling, and that this effect increases the closer in the family’s birth order the first exposed brother is to the girl. This result is consistent with a model in which families learn about school quality and allocate more resources to the production of learning (i.e. hours of their children's time) when the quality of complementary inputs increases.
