Abstract
Leveraging a randomized natural experiment, this study examines the impact of attending single-sex middle schools on students' physical fitness, measured through standardized nationwide physical tests. In South Korea, middle school students are assigned by lottery to either single-sex or coeducational schools within their designated school zones, providing an ideal setting to evaluate the effects of single-sex schooling. Using school-level data covering all middle schools, the study finds that boys attending single-sex schools achieve significantly higher pass rates on standardized physical fitness tests, suggesting improved physical fitness compared to their peers in coeducational schools. However, no similar improvement is observed for girls attending single-sex schools. These findings suggest that single-sex schooling has differential effects by gender, highlighting the need to further research to understand the mechanisms underlying these varied outcomes.
期刊介绍:
Many economists today are concerned by the proliferation of journals and the concomitant labyrinth of research to be conquered in order to reach the specific information they require. To combat this tendency, Economics Letters has been conceived and designed outside the realm of the traditional economics journal. As a Letters Journal, it consists of concise communications (letters) that provide a means of rapid and efficient dissemination of new results, models and methods in all fields of economic research.
