How Feeling Financially Constrained Decreases Participation in Access-Based Services Emanuela Stagno, BI Norwegian Business School, Norway Klemens Knoferle, BI Norwegian Business School, Norway Luk Warlop, BI Norwegian Business School, Norway Feeling financially constrained influences consumer attention and behaviors. We propose that this feeling also affects the propensity to engage in alternative consumption modes; namely access-based consumption. Two experiments test whether financially constrained consum- ers are less willing to participate in access-based services. The preliminary findings seem to not support our hypothesis. The Role of Consumer Self-identities and Individual Tendencies in Food Waste Violeta Stancu, Aarhus University, Denmark Liisa Lähteenmäki, Aarhus University, Denmark There are several well-established negative consequences of food waste for the environment and society. Consumers’ environmental or frugal self-identities are associated with lower self-reported food waste. On the other hand people’s impulsive buying tendency and disgust sensitivity are important factors that associate positively with consumer food waste. The Role of Multiple Self-Identities in Behaviours Across the Consumption-cycle in Food and Apparel Catalin Mihai Stancu, Aarhus University, Denmark Alice Grønhøj, Aarhus University, Denmark Liisa Lähteenmäki, Aarhus University, Denmark Consumers have several self-identities which impact sustainable behaviours. Frugal self-identity was found to have stronger associations with specific categories of behaviours in the consumption-cycle. While sustainable self-identity positively predicted behaviours across the consumption-cycle frugal thrifty or trendy self-identities had both positive and negative relations to behaviours outlining potential clashes. Embracing and Rejecting “Sparking Joy”—Understanding Japanese Consumer Responses to Marie Kondo’s Original Book Sumire Stanislawski, Tokyo International University, Japan Shuji Ohira, Chiba University of Commerce, Japan Kosuke Mizukoshi, Tokyo Metropolitan University, Japan By examining responses to Marie Kondo’s original book consumer reactions to a taste regime counter to mainstream consumerism are explored. Those who embraced and rejected her message were analyzed using text mining. Some internalized new meanings surrounding consumption while others rejected her legitimacy as an influencer of taste.
