This study aims to examine whether, and how, perceived product scarcity strengthens the attitude–behavior relation in the case of sustainable luxury products.
Three online studies were conducted to examine the moderating role of perceived product scarcity on the attitude–willingness to pay (WTP) relationship in the case of sustainable luxury products. A preliminary study ( n = 208) examined the existence of an attitude–WTP gap toward a sustainable luxury product (i.e. a bag). Study 1 ( n = 171) investigated the moderating effect of perceived scarcity induced by a limited quantity message on the relationship between consumer attitude and the WTP for a sustainable luxury product (i.e. a pair of shoes). Study 2 ( n = 558) replicated these findings using a different product category (i.e. a wallet) while controlling for demographic variables and examined the moderating role of consumer characteristics on the scarcity effect.
Consumers’ perceived scarcity for sustainable luxury products positively moderated the relationship between product attitudes and their WTP for the products. The moderating effect of perceived scarcity was significant for consumers regardless of their tendency toward socially responsible consumption and their preference for product innovativeness. Meanwhile, the scarcity effect was influenced by the consumers’ attitude toward the brand of sustainable products.
