This paper estimates the impact of peer achievement and variance on math achievement growth. It exploits exogenous variation in peer characteristics generated at the transition to upper-secondary school in a sample of Berlin fifth graders. Parents and schools are barely able to condition their...

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...

This paper estimates ability peer effects on achievement growth in reading and math. It exploits variation in peer characteristics generated at the transition from primary to secondary school in a sample of Berlin fifth-graders. As will be discussed in detail, this variation is exogenous in...
