Peer effects in education

How do classmates and peers influence students’ learning, choices, and future prospects? This project explores how the people around us shape educational outcomes - both in and beyond the classroom.

From preschool to adult education, students are influenced by their peers. These peer effects can be positive - encouraging better habits and achievement - or negative, leading to issues like school absence or disengagement. Research shows that peer effects are often even stronger for behavior than for grades.

This project digs deeper into how peer effects work. It challenges the idea that these effects are always “average” or equal for everyone. For example, do struggling students benefit more from high-performing classmates than those classmates are held back? And how much do neighborhood and family background play into it?

Using detailed data from Swedish schools, the project examines how peers in school, family, and neighborhood settings affect students’ education paths and later success in the labor market.
