This paper provides the first analysis of the relationship between the language mix of Limited English Proficient (LEP) peers and student achievement, using detailed panel data from 2006 to 2012. Percent LEP has a negative association with mathematics and reading test scores, more so for non-LEP...

We investigate the effect of peer group composition on language improvement in language classes for adults. Using unique survey data of migrants participating in an intensive language course in Germany, we find that the age and skill composition of groups affect skill acquisition as assessed by...

While the share of non-native students in a class is expected to have a non positive effect on school achievement, little is said about the heterogeneity of the ethnic minority make-up. Ethnic diversity can stimulate the creativity of students, can push them to be proficient in the instructional...

There is a large literature on social interactions and still little is known about the economic mechanisms leading to the high level of clustering in behavior that is so commonly observed in the data. In this paper we present a model in which agents are allowed to interact according to three...

We study the effects of informal social interactions on academic achievement and behavior using idiosyncratic variation in peer groups stemming from changes in bus routes across elementary, middle, and high school. Our results suggest that student interactions outside the classroom - especially...
