“…Ethnic competition theory has its roots in realistic group conflict theory and social identity theory (Brown, 2000; Esses, Jackson, and Armstrong, 1998; Pryce, 2018; Scheepers, Gijsberts, and Coenders, 2002; Sherif, 1966; Sherif and Sherif, 1969; Tajfel and Turner, 1979; Tajfel, 1982). Realistic group conflict theory, which maintains that competition over scarce resources between groups would lead to negative intergroup relations and possibly conflict (Bobo, 1988; Esses, Jackson, and Armstrong, 1998; LeVine and Campbell, 1972) and social identity theory, which assumes that a central mechanism for negative attitudes toward others is the propensity to perceive one's group as superior to other groups, both undergird ethnic competition theory.…”
