@techreport{oai:grips.repo.nii.ac.jp:00001532, author = {CHEN, Stacey H. and CHEN, Yen-Chien and LIU, Jin-Tan}, note = {Parents preferring sons tend to go on to have more children until a boy is born, and to concentrate investment in boys for a given number of children (sibsize). Thus, having a brother may affect child education in two ways: an indirect effect by keeping sibsize lower and a direct rivalry effect where sibsize remains constant. We estimate the direct and indirect effects of a next brother on the first child’s education conditional on potential sibsize. We address endogenous sibsize using twins. We find new evidence of sibling rivalry and gender bias that cannot be detected by conventional methods., This is a heavily revised version of Chen, Chen and Liu (2014)., Financial support from the Academia Sinica Career Award (103-H02), Taiwan’s National Science Council (NSC 101-2628-H-001-001-MY3) and National Health Research Institute.}, title = {The Impact of Family Composition on Educational Achievement} }
