This paper investigates how exposure to higher-achieving male and female peers in university affects students' major choices and labor market outcomes. For identification of causal effects, we exploit the random assignment of students to university sections in first-year compulsory courses. We...

This paper provides evidence on ability peer effects in university education. Identification comes from the random assignment of students to sections. We find that students on average benefit from better-ability peers. Low-ability students, however, are harmed by high-ability peers. We introduce...

Many universities around the world rely on student instructors — current bachelor's and master's degree students — for tutorial teaching, yet we know nothing about their effectiveness. In a setting with random assignment of instructors to students, we show that student instructors are almost...

A substantial share of university instruction happens in tutorial sessions—small group instruction given parallel to lectures. In this paper, we study whether instructors with a higher academic rank teach tutorials more effectively in a setting where students are randomly assigned to tutorial...
