This paper aims to identify which Schwartz values and regulatory focus orientations influence consumer behavior on the food market in the domain of preference for domestic products, which is closely related to consumer ethnocentrism. The CAWI (Computer-Assisted Web Interviews) method was applied. The sample consisting of 1000 respondents was representative for the Polish adult population in terms of sex, age, education, place of living (rural vs. urban), and region. The willingness to pay (WTP) a higher price for domestic products was affected by the tradition and universalism values. Consumer value orientations and regulatory focus were more powerful in explaining the WTP than demographic or socio-economic variables. The theories of value orientations and regulatory focus were found to be more relevant for men than for women, as reflected in adjusted regression determination coefficients. Finally, the promotion regulatory focus was a significant predictor of the WTP among men, but not among women. Based on my findings, it is recommended (1) to emphasize the following elements in marketing communications in order to stimulate the purchases of domestic food products: appeals to tradition, customs, ecology, being natural; (2) to take into account the Schwartz values in consumer segmentation on the food market; (3) to differentiate marketing communications for domestic food products on the basis of gender segmentation: in messages addressed to male consumers, arguments appealing to the promotion orientation should be used more frequently.
