“…As the experiment took place outside the university, at an event of widespread interest to the town’s population, we anticipated a more varied sample compared to Experiment 1 regarding age and educational backgrounds. Since the applicability of nudge intervention depends on situational and contextual constraints ( Czajkowski et al, 2019 ; Grilli and Curtis, 2021 ; Mertens et al, 2022 ; Dannenberg and Weingärtner, 2023 ), the examination of the nudge’s effectiveness with a different target group is vital for practical recommendations. We kept the area of application (paper towel use in public women’s toilets) and the nudge itself constant in order to be able to make appropriate statements about the scalability of the nudge intervention regarding other demographic characteristics of the target group.…”

“…In doing so, we aimed for developing a social norm nudge that is ready-for-implementation. So far, situational and contextual variables have gained little attention in the nudging literature (e.g., Czajkowski et al, 2019 ; Grilli and Curtis, 2021 ; Mertens et al, 2022 ; Dannenberg and Weingärtner, 2023 ). In the present work, one specific nudge was developed and tested in different situational contexts.…”

“…While numerous studies substantiate and underscore the success of nudging, there is also literature casting doubt on its overall efficacy ( Maier et al, 2022 ), along with discussions on the circumstances under which nudging proves effectiveness (e.g., Costa-Font et al, 2014 ; Lehner et al, 2016 ; Szaszi et al, 2018 ). A central finding from this critical discourse concerns the limited generalizability of the individual nudge intervention, since the success of a nudge intervention depends on situational and contextual factors (e.g., Czajkowski et al, 2019 ; Grilli and Curtis, 2021 ; Mertens et al, 2022 ; Dannenberg and Weingärtner, 2023 ).…”

“… DellaVigna and Linos, 2022 ). Further, by examining samples that differ in their demographic characteristics, we gain knowledge about potential target groups of this intervention method, since people respond differently to social norms (e.g., Czajkowski et al, 2019 ; Dannenberg and Weingärtner, 2023 ).…”

Social norm interventions hold the potential to change people’s behavior. Five field experiments (N = 1,163) examined the effects of a simple and easily realizable social norm nudge based on the social media format “Be like Bill.” The nudge consisted of a stick figure named Toni that communicated descriptive and injunctive norms regarding pro-environmental or pro-social behaviors. Nudge conditions were compared to no-intervention control conditions. Experiment 1 (N = 179) focused on paper towel consumption in a women’s restroom at a German university. The nudge condition used less paper towels than the control condition, d = 0.48. Experiment 2 (N = 183) replicated this result (d = 0.32) in a more diverse setting of a women’s restroom at a German Christmas market. Experiment 3 (N = 250) examined differences in the effects of prescriptive (i.e., ‘do-norm’) versus proscriptive (i.e., ‘do not-norm’) social norms on paper towel consumption again in a university women’s restroom. The effectiveness of both social norm nudge conditions was shown in comparison to the control condition (d = 0.46; d = 0.40), while the prescriptive and proscriptive social norm manipulations did not differ. Experiment 4 (N = 206) applied the nudging approach to the use of plastic lids in a coffee shop, where no effect was found. Finally, Experiment 5 (N = 345) focused on the pro-social behavior of mask wearing in a bakery toward the end of the Covid-19 pandemic restrictions in Germany. In the nudge condition, more visitors put on face masks compared to the control group, d = 0.39. Limitations and contextual factors regarding the applicability of our social norm nudge are discussed.

Consumer preferences for commission rates in the online food delivery industry: a willingness-to-pay approach

PurposeFood service establishments and online food delivery companies use a revenue share model based on a commission rate. Because of the asymmetry of bargaining power, many food service establishments are vulnerable to a high commission rate. What is missing in the ongoing discussion about the revenue share model is the perspective of food consumers, who are the third party in the multi-sided market.Design/methodology/approachWithin a willingness-to-pay (WTP) framework, we study if food consumers have preferences for the commission rate charged by food delivery companies to food service establishments. With 456 random consumers in the United States, we conduct a controlled experiment in which information is used as treatment in two groups. In the first group, the provided information only relates to the revenue share model (i.e. economic). In the second group, participants also received information about price control initiatives (i.e. economic and political).FindingsBased on WTP-space mixed logit model results, there is a significant effect of information on preferences for the commission rate. While participants in the control group exhibited no aversion to the commission rate, participants who received treatment had a significant and negative WTP. The magnitude of the effect is estimated at -$1.08 for participants in the first treatment and -$2.28 for participants in the second treatment.Originality/valueTo date there is no applied research on the preferences of consumers in the online food order and delivery industry with respect to upstream conditions (i.e. commission rates).

Food production is a primary contributor to climate change, and one way to mitigate its effect is through consumption choices. Finding the most effective way to achieve emissions reduction via consumers behavioral change has recently raised policy-makers' interest but experimental evidence about this is still scarce. In this study, we examine the impact of individualized information about greenhouse gas emissions on grocery purchases. Using a randomized field experiment, we compare the effects of individualized information on the carbon footprint of grocery purchases to individualized information on grocery spending provided through a smartphone app. Compared to the spending information, the carbon footprint information decreases emissions from groceries by 27% in the first month of treatment, with 45% reductions in emissions from beef, the highest emissions food group. Treatment effects fade in the longer run along with app engagement but persist among those engaged with the app. Our results suggest that the provision of emissions information, in particular when paired with sufficient engagement, is a promising avenue for policies to turn food consumption greener.
