Social environment is usually considered as a randomly formed group. However, it forms and develops as a result of an individual conscious dynamic choice. Students may initially choose friends among peers with similar level of academic performance, and the influence of close friends on each other’s achievements may reveal itself over time. Using stochastic actor-based models, we demarcated the boundaries between social selection and social influence evaluated through academic performance. Having analyzed the dynamics of friendship ties and academic achievements throughout the first year at university, we discovered that students were not guided by the level of academic performance when choosing friends among peers but academic achievements of the latter affected their own performance over time. This could be explained by social segregation of students based on their academic outcomes.  AU - Sofia Dokuka AU - Diliara Valeeva AU - Maria Yudkevich UR - https://archive_vo.hse.ru/en/2015--3/160470693.html PY - 2015 SP - 44-65 VL -
