Food waste, especially at the retail and consumer level, is a critical societal issue. Consumers' reluctance to purchase and consume near-expired food is a major contributor. Retailers have taken actions to promote near-expired food; however, it is unclear how their actions influence both purchase and consumption of near-expired food. This research examines one retail strategy aiming to reduce food waste-a message about food waste avoidance (without discounts). Specifically, four experiments (N = 1196) using various measurements of food waste prevention behaviors and one single-paper meta-analysis reveal that a message about food waste avoidance increases consumers' willingness to buy near-expired food through increased moral satisfaction. After purchasing near-expired food, consumers engage in more waste prevention behaviors for it than for other food regardless of whether consumers encounter the food-waste-avoidance message. In addition, we find indications that increased moral satisfaction deriving from the food-waste-avoidance message motivates consumers to conduct more household waste prevention behaviors for the purchased near-expired food. Together, these findings suggest that a message about food waste avoidance can be a potentially effective strategy to reduce the waste of near-expired food. This research extends our understanding of the purchase and consumption of near-expired food and supports retail messages about food waste avoidance to sell near-expired food.

Saving money is important but challenging. To spur financial saving intentions, we propose a new strategy—gamification. Specifically, we investigate the effectiveness of competitive leaderboards in increasing individuals’ saving intentions. The results of two studies (total N = 618) show consistently that people’s saving intentions are higher when presented with a leaderboard than when not. Further, as leaderboards elicit social comparison, we explore whether the height of the comparison standard and individuals’ social comparison orientation moderate the effect. We find that the effect of leaderboards on saving intentions is more pronounced when people compare with a higher (as compared to a lower) standard (Study 1), but that the effect is not influenced by individuals’ social comparison orientation (Study 2). Taken together, this research provides a new and simple-to-implement strategy to facilitate saving intentions in order to help improve people’s financial well-being.

During social interactions, individuals frequently experience interpersonal insecurity, including feelings of not being loved, protected, trusted, or cared for; these feelings cause numerous behavioral consequences. The present research explores the relationship between interpersonal insecurity and risk-taking propensity in multiple risk domains and around the globe based on risk-sensitivity theory and research on group identity. In Study 1, participants ( N = 209) reported their interpersonal insecurity and risk-taking propensity across seven risk domains. The results show that risk-taking propensity generally increases with interpersonal insecurity. However, this relationship was negative in the cooperation domain and null in the financial domain. In Study 2 ( N = 128,162), data from the World Values Survey from 77 countries reveal a positive correlation between risk-taking propensity and interpersonal insecurity with in-group members but a negative relationship between risk-taking propensity and interpersonal insecurity with out-group members.
