This paper looks at the effects of providing broadband to schools on students’ performance. We use a rich panel of data on broadband use and students’ grades from all middle schools in Portugal.

During baseline many students riding their bikes to and from school did not wear their helmets or wore them incorrectly.

We estimate the impact of peer gender composition on student achievement, exploiting the random assignment of Korean middle school students to single-sex schools, coeducational schools with single-sex classes, and coeducational schools with mixed-gender classes. Male students attending coeducational schools with single-sex classes perform worse than boys in mixed-gender classes, while those ass...
