Consumer ethnocentrism

Consumer ethnocentrism is derived from the more general psychological concept of ethnocentrism.

Basically, ethnocentric individuals tend to view their group as superior to others. As such, they view other groups from the perspective of their own, and reject those that are different and accept those that are similar (Netemeyer et al., 1991; Shimp & Sharma, 1987). This, in turn, derives from earlier sociological theories of in-groups and out-groups (Shimp & Sharma, 1987). Ethnocentrism, it is consistently found, is normal for an in-group to an out-group (Jones, 1997; Ryan & Bogart, 1997).
