Using data from the 2005 Survey of Freshmen in the Integrated Higher Education Database System in Taiwan, we study the gender differences in student loan take-up rates. After controlling for family income, parental education and other control variables, female students still are more likely to have student loans. In addition, gender differences in student loans only exist among students from families with both sons and daughters, but not among those from families with sons or daughters only. This shows that the gender differences in student loans are the results of parental choice of human capital investment in children.
