This study examined the noneconomic factors affecting consumers’ participation in purchase decisions, focusing in particular on the social aspect of the buyer‐seller interaction. In addition, we attempted to clarify the association between consumer participation and price sensitivity. Of the four social dimensions of consumer participation—preparation, relationship building, information exchange, and intervention—our results indicated that the first three dimensions are negatively associated with price sensitivity but the intervention dimension is not. Additionally, we also found that, given the same level of preparation, industries typically characterized by higher participation, such as hair salons, are associated with lower consumer price sensitivity as compared to those typically characterized by lower participation, such as fast food restaurants. Similarly, given the same level of relationship building, information exchange, and intervention, industries typically characterized by higher participation have lower consumer price sensitivity than those typically characterized by lower participation.
