We investigate the role of identity and self-image consideration under "pay-what-you-want" pricing. Results from three field experiments show that often, when granted the opportunity to name the price of a product, fewer consumers choose to buy it than when the price is fixed and low. We show that this opt-out behavior is driven largely by individuals'(More)
Building on previous research in economics and psychology, we propose that the costliness of initial prosocial behavior positively influences whether that behavior leads to consistent future behaviors. We suggest that costly prosocial behaviors serve as a signal of prosocial identity and that people subsequently behave in line with that self-perception. In(More)
Unlike most species, humans cooperate extensively with group members who are not closely related to them, a pattern sustained in part by punishing non-cooperators and rewarding cooperators. Because internally cooperative groups prevail over less cooperative rival groups, it is thought that violent intergroup conflict played a key role in the evolution of(More)

Despite the ongoing need for shark conservation and management, prevailing negative sentiments marginalize these animals and legitimize permissive exploitation.

Social behavior is heavily influenced by the perception of the behaviors of others. We considered how perceptions (and misperceptions) of kindness can increase generosity in economic transactions. We investigated how these perceptions can alter behavior in a novel real-life situation that pitted kindness against selfishness. That situation, consumer(More)
People often use price as a proxy for quality, resulting in a positive correlation between prices and product liking, known as the " price– quality " (P–Q) heuristic. Using data from three experiments conducted at a winery, this article offers a more complex and complete reference-dependent model of the relationship between price and quality. The authors(More)
