Since the 1980s, the BC Ministry of Education has offered funding to support the language development of students who speak non-standard dialects of English. In practice, the students who are supported by this funding are almost exclusively Aboriginal, and English as a Second Dialect (ESD)...

We use administrative data on students in grades 4 and 7 in British Columbia to examine the extent to which differences in school environment contribute to the achievement gap between Aboriginal and non-Aboriginal students as measured by standardized test scores. We find that segregation of...

We use data on elementary-school students to investigate how the home language and other characteristics of a student's same-grade schoolmates influence that student's academic achievement. We exploit the availability of multiple cohorts of data within each school to control for endogenous...

We use data on students in grades 4–7 in the Canadian province of British Columbia to investigate the effect of having disabled peers on value-added exam outcomes. Longitudinal data for multiple cohorts of students are used together with school-by-grade-level fixed effects to account for...

We examine the contribution of differences in school environments to the gap in education outcomes between Aboriginal and non-Aboriginal students. We find both substantial school-level segregation of Aboriginal and non-Aboriginal students and a substantial gap in test scores. Conventional...

The influence of peer behavior on an individual's choices has received renewed interest in recent years. However, accurate measures of this influence are difficult to obtain. Standard reduced-form methods lead to upwardly biased estimates due to simultaneity, common shocks, and nonrandom peer...

A number of studies have indicated that peer smoking is a highly influential factor in a young person's decision to smoke. However, these results are suspect because the studies often fail to account for selection and simultaneity bias. This paper develops an econometric model of youth smoking...

In the well-known `critical mass' model of social interactions, aggregate behaviour exhibits multiple equilibria if the influence of group behaviour on individual behaviour exceeds some fairly high threshold. I demonstrate that this property depends on an implicit assumption that the relevant...
