How is the concept of ethnocentrism related to country-of-origin effects?

Ethnocentrism is the tendency to prefer products or people of one's own culture over those from other countries. A product's country of origin can function as a stereotype-a knowledge structure based on inferences across products. For example, a consumer can perceive a product as being of high quality because it was made in a certain country. A highly ethnocentric consumer would likely perceive products that come from their own country as being of higher quality.
