Researchers and educators often argue that a student's peers strongly influence his or her educational outcomes. If so, an unequal distribution of advantaged and disadvantaged students across schools in a community will leave many students doubly disadvantaged and amplify existing inequalities....

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...

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)...

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...

This paper investigates the properties of a local economy in which personal connections are important in finding jobs. The complementarities in the model generate an interesting nonlinear relationship between the distribution of human capital in the economy, the characteristics of the social...

This paper finds that the predicted unemployment rate in a community increases dramatically when the fraction of neighborhood residents with college degrees drops below twenty percent. This threshold behavior provides empirical support for "epidemic" theories of inner-city unemployment. Using a...

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...

Traditionally, econometric research on social interaction effects has used fairly large social groups (schools, Census tracts, etc.). However, new data which describes the behavior of much smaller peer groups is becoming available. This paper analyzes the behavior of "small neighborhoods" in the...
