This paper presents a small theoretical model to compare school systems that segregate students by ability ('tracking') with comprehensive ones, which allow for mixing of differently skilled students into same classes. The outcomes of interest are the achievement levels of weaker and better...

Using a theoretical model where students care about achievement rank, I study effort choices in the classroom and show that rank concerns generate peer effects. The model’s key empirical prediction is that the effect on own achievement of increasing the dispersion in peer cost of effort is...
