The effect of persuasive messaging on attitude and intention to reduce meat consumption – a mediation analysis
Purpose To support the transition to a healthy and sustainable diet, interventions aimed at reducing meat consumption among consumers are essential. This study aims to examine the effectiveness of a messaging intervention to influence consumer attitudes and intention regarding meat consumption. We hypothesized that the impact of messaging on intentions would be mediated by changes in implicit and explicit attitudes. Additionally, we explored the …
Evaluating nudge and boost strategies for greener meals in food-delivery: An experimental study
emissions, whereas the boost intervention yielded considerably smaller and less consistent effects. However, neither intervention produced lasting effects in the follow-up survey, where choice architecture reverted to the control condition. Moreover, while higher CRSC induced lower emissions, neither the nudge nor the boost elevated CRSC, and thus the hypothesized mediating role of consumer responsibility was not supported. We discuss the theoret…
The role of information and taste in consumer preferences for aquaponic tomatoes: An experimental study
By combining vegetable and fish production in a closed-loop system, aquaponics is a promising technology to contribute to sustainable food production. However, information about consumer preferences for aquaponic products is limited and most studies measure willingness to pay hypothetically. The present study aims to fill that gap by conducting a non-hypothetical incentive-compatible experimental auction study with 287 students. We followed a 3*3…

Every step you take: Nudging animal welfare product purchases in a virtual supermarket
Animal welfare (AW) is a growing concern for consumers in Germany; however, not all consumers regularly purchase products that have been produced according to high AW standards. The goal of the present study is to test the effect of a multilayered nudge to increase the availability and improve the visibility of AW products in a 3D online virtual supermarket (VS). The nudge included a shelf with AW products (referred to as AW shelf) which was made…
Digital platforms in the agricultural sector: Dynamics of oligopolistic platformisation
This paper introduces the concept of 'oligopolistic platformisation' to capture the specific dynamics of collaboration and competition between multinational upstream agribusinesses and Big Tech companies in the agricultural (ag) sector. We examine this phenomenon through the lens of Van Dijck et al.'s platform mechanisms: datafication, selection and commodification. Multinational agribusinesses operate sectoral ag platforms that analyse spatial, …
Let's talk about straw: The effect of information provision on consumers' attitudes towards pig husbandry systems
Purpose The type of flooring in stalls is an important factor that shapes consumers' overall perception of animal husbandry. Although slatted and straw floors have benefits and drawbacks, consumers strongly prefer slatted over straw floors in pig husbandry. The present study investigates whether information provision can depolarise consumers' implicit and explicit attitudes towards both floor types to enable a more realistic evaluation of pig hus…

Insights into the organic labelling effect: The special case of wine
Purpose While research shows that organic labels are perceived positively for most food products, the findings are more ambiguous for wine. This may be due to the complexity of the product. Accordingly, the labelling effect might be influenced by people's prior knowledge of wines and their attitudes towards organic wines and thus be more pronounced for certain consumer groups. Providing insights into those moderators could help to steer people to…

Looking behind the choice of organic: A cross-country analysis applying Integrated Choice and Latent Variable Models
This cross-country study investigates the relative role of organic labelling in consumers' purchase decisions for apples and the extent to which behavioral constructs, derived from an extension of the Theory of Planned Behavior, influence consumers' choices. We apply an Integrated Choice and Latent Variable Model, combining a discrete choice experiment with structural equation modelling. Empirical validation draws on data from an online survey co…
Industry self-regulation of food advertisement to children: Compliance versus effectiveness of the EU Pledge
Does the distribution frequency matter? A subgroup specific analysis of the effectiveness of the EU School Fruit and Vegetable Scheme in Germany comparing twice and thrice weekly deliveries
Objective The present study aimed to examine the effectiveness of two different implementation forms of the EU School Fruit and Vegetable Scheme (SFVS). Design A quasi-experimental design was applied including a thrice as well as a twice weekly intervention group. Repeated 24 h dietary recalls were used to measure children’s fruit and vegetable (F&V) intake. Effects were analysed on days with and without F&V deliveries using hierarchical linear r…

The European School Fruit Scheme: Impact on children’s fruit and vegetable consumption in North Rhine-Westphalia, Germany
Objective To assess the impact of the European School Fruit Scheme (SFS) in North Rhine-Westphalia, Germany, on children’s fruit and vegetable (F&V) consumption, in particular frequency. Design The study consisted of a pre-test/post-test design with an intervention (eight primary schools) and a control group (two primary schools). Children’s F&V consumption frequency was measured prior to the introduction of the SFS in 2010 and after one year’s d…

Health-related on-pack communication and nutritional value of ready-to-eat breakfast cereals evaluated against five nutrient profiling schemes
Our results suggest that the implementation of a mandatory nutrient profiling scheme for products with health-related on-pack information could contribute to a consistent relationship between health-related information on RTECs and the overall nutritional value of the product. Improvements should also consider the provision of a simple nutritional labelling scheme on the front of the packaging, standardized serving sizes, accurate product names, …
