ABSTRACT
This 2015 cross-sectional study tested whether the level of competition affected the national test scores of senior high schools in Jakarta. We measured the level of competition using the Herfindahl-Hirschman Index (HHI) and a gravity-based school competition index for the number of enrolled students. We found that schools’ national exam scores were positively associated with the level of competition. Furthermore, this competition was better explained by physical proximity than by administrative boundaries. However, public schools did not benefit from the competition.
