"The Maternal and Sibling Spillover Effects in Educational Attainment" (with Suyong Song). Submitted. Paper

Abstract: This paper estimates maternal and sibling spillover effects in educational attainment based on data from the NLSY surveys. Using an instrumental variable strategy, this study shows that a one-year increase in first-born’s education causes a significant increase of 4.5 months in younger sibling’s schooling and a one-year increase in maternal education significantly increases child’s education by around 3 months. It also finds that the higher the birth order, the smaller the maternal and first-born’s spillover effects. These findings emphasize the importance of both mother’s and sibling’s education in understanding the human capital production function and estimating education externalities.

Abstract: This paper estimates the contemporaneous effects of family income and maternal employment on cognitive and non-cognitive skills of children ages 5-16 using an instrumental variable strategy. By making use of legislative changes associated with income tax liabilities and interstate banking as instruments, this study makes important improvements to the methodologies existing in the literature. It shows that family income has a significant positive effect on child's cognition only. The impact of maternal work is significant on both cognitive and several non-cognitive dimensions. The maternal work effect on non-cognition cannot be generalized in any direction but it is deleterious on cognition.
