Note. The behavioral dynamics models perceived discrimination and the network dynamics models friendship choices. Model 1 tests contact effects and the corresponding selection effects. Model 2 tests contact effects, socialization effects, and the corresponding selection effects. Models include the effects for structural controls and White students shown in online Appendix C. Est. = estimate; SE = standard error. N = 1,170. Ethnicity coded as 1 = White, 2 = Asian. Gender coded as 1 = boy, 2 = girl.
