RT Journal Article SR Electronic T1 Sibling Gender, Inheritance Customs and Educational Attainment JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 1023-13197R2 DO 10.3368/jhr.1023-13197R2 A1 Collins, Matthew YR 2025 UL http://jhr.uwpress.org/content/early/2025/08/01/jhr.1023-13197R2.abstract AB This study identifies the causal effect of second-born gender on the education of first-born children and how it varies across traditional inheritance customs in 27 sub-Saharan African countries. When customs dictate that sons do not inherit from fathers, having a brother causes a 0.05 SD reduction in education. For boys who inherit, having a brother reduces inheritance, for which parents substitute greater educational investments. For first-born girls whose brother can inherit, having a brother causes a 0.028 SD reduction in education. Exploiting national legal reforms, I show that sibling gender effects converge when all children can inherit from their parents.
