While the current empirical literature on peer group effects in schools highlights that credible causal peer effects cannot be estimated unless parental sorting is taken into account, the present paper highlights that causal peer effects might be conditional on the learning environment in which...

We use data from a large field experiment where young students were pulled out of their regular classes and offered mathematics instruction in small homogenous groups, to investigate the importance of the tutors' instructional practices. The analyzes are limited to low achievers, and the...

The current empirical literature on peer group effects in schools highlights that credible causal peer effects cannot be estimated unless parental sorting is taken into account. Motivated by a small theoretical literature that discusses resource allocations within schools, the present paper...

We investigate whether the academic performance of non-eligible students – in an institutional setting of full inclusion - are affected by special education resources. Special education resources are per definition provided in a compensatory manner, and are increasingly being targeted to...

This paper uses data from the Norwegian elementary school to test whether students from disadvantaged backgrounds benefit from smaller classes. The data cover one cohort of fourth graders who have been treated in small versus large classes for a period of three years. The Norwegian class size...
