Large digital platforms face intense scrutiny over self-preferencing, which involves a platform provider favoring its own offers over those of competitors. In online marketplaces, also called retail or e-commerce platforms, much of the academic and regulatory debate focuses on determining whether the marketplace provider gives preference to its own private labels, such as “Amazon Basics” or Walmart’s “Great Value” products. However, we outline, both conceptually and empirically, that self-preferencing can also occur through other dimensions of vertical integration – namely, retailing and fulfillment.

This article contributes by conceptualizing three dimensions of vertical integration in online marketplaces – private labels, retailing and fulfillment. Then, two studies empirically assess (1) which of the 20 most-visited global online marketplaces vertically integrates which dimension and (2) which share of 600 m available offers is vertically integrated to which degree in eleven international Amazon marketplaces.

The majority of the leading marketplaces vertically integrate all three dimensions, implying ample opportunities for self-preferencing. Across international Amazon marketplaces, only 0.02% of available offers consist of an Amazon private-label product. However, Amazon is a retailer for around 31% and fulfills around 38% of all available offers in its marketplaces. Hence, self-preferencing on Amazon can occur most frequently through retailing and fulfillment but comparatively infrequently through private-label offers. Still, these shares differ substantially by country – every second offer is vertically integrated in the USA, but only one in ten in India.

Most of the self-preferencing debate often focuses on private-label products. Instead, we present large-scale empirical results showing that self-preferencing on Amazon could occur most often through retailing and fulfillment because these channels affect much larger shares of offers. We also measure the variation of these shares across countries and relate them to regulatory environments.

This paper aims to understand how dual sustainable-labeling strategies influence perceived value dimensions (i.e. quality, emotional, social and price) across vice vs virtue products and level of consumers’ consideration of future consequences.

Two online experiments are conducted with private label brands: one with organic and Fairtrade labels and one with organic and local labels. For each experiment, a conditional process analysis was used with the labeling strategy (i.e. no label vs organic label vs Fairtrade/local label vs organic label + Fairtrade/local label) as the independent variable, the product types (i.e. vice vs virtue) and level of consideration of future consequences as moderators, the dimensions of perceived value (quality, emotional, social and price) as the dependent variables.

Dual sustainable-labeling strategies lead to higher positive perceived value levels on all dimensions compared to no-labeling strategy. They however do not necessarily lead to higher levels compared to mono-labeling strategies such as organic labeling strategy (except for social dimension). Additionally, the positive effect of dual sustainable-labeling is lower for virtue products compared to vice products and is stronger for consumers with high level of consideration of future consequences for vice products for the social-value dimension.

Prior research has focused on the effect of multi-labeling strategies on willingness to pay with mixed results. This study brings insights to literature by testing the impact of dual sustainable-labeling strategies on the dimensions of perceived value as well as the moderating effects of the product types and consideration of future consequences.

This paper aims to understand how support organizations promote the structuring of the agricultural value chain through partnerships and capacity building of the various links in the chain.

The study is exploratory and qualitative, based on ten semi-structured interviews with the main public support organizations related to the date sector in Tunisia.

The results showed that the support organizations of the Tunisian date sector do not share the same vision of the priorities to be strengthened to promote the export of dates in Tunisia.

Reviewing the coordination mechanisms between the support organizations is important in order to improve the governance of the value chain and to reinforce the capacity of the operators in the date value chain.

Public support organizations are important actors in agricultural value chains as these organizations implement agricultural policies. Assessing these organizations' contribution to capacity building of chain links is an innovative approach to detecting organizational dysfunction in agricultural value chains in developing countries.

There are calls for irradiated food labelling due to a significant need for food safety and extensive procedures to safeguard consumer health. Additionally, there is a strong push from producers for mandatory Country of Origin (COO) labelling. The study examines how the COO and Radura labels influence consumer behaviour and shows the interplay between these influences. Using Attitude-Behavior-Context theory, a conceptual model is proposed and tested to evaluate these factors. The use of multiple labels allows for more choices. How the information presented on labels corresponds to consumers' pre-purchase information search is tested on regular label users.

Structural Equation Modelling (SEM), Generalised Linear Modelling and Cluster Analysis were used to analyse the data on a sample of 322 Australian respondents.

The study revealed that COO labelling had a significant positive relationship with attitudes but a negative relationship with WTP, acting as a suppressed mediator between attitudes and WTP. Interestingly, while knowledge was not found significant, label confidence emerged as a significant factor. Furthermore, the research suggests that regular users may prioritize COO labels over Radura labels.

This research contributes novelty by being the first to address the interplay between COO and irradiated labels, complementing the growing body of literature on irradiation labelling. It also offers valuable insights for retail practitioners, providing an understanding that can facilitate the delivery of high-value multiple labels at the point of purchase.

In a context where the sharing economy (SE) plays an important role in the transformation of today’s business landscape, profoundly changing the behavior of consumers and many established companies, some companies have begun to adapt to SE by incorporating its value propositions into their business models. Therefore, the purpose of this paper is to study the role of consumer innovativeness, brand levels and the need for uniqueness on the way to attitudes and intentions to participate in SE.

This study collected the data through an online user survey, achieving a total sample of 717. The data were first analyzed using structural equation modeling and then combined with the use of the PROCESS macro.

The findings provide empirical evidence of the antecedents of consumer innovativeness in a SE context and its role in explaining consumer attitudes and intentions to participate in non-ownership consumption. Furthermore, they also demonstrate that brand tiers and the need for uniqueness moderate the relationship between intentions and participation.

The results of this study contribute to the theoretical development of the SE by presenting the first conceptual model that considers including the brand tiers effect and connects it to two leading theories on consumer behavior (diffusion of innovations theory and uniqueness theory). In addition, the study’s findings provide valuable insights for sharing platforms and traditional companies that choose to participate in the collaborative economy.

Sustainable consumption has far-reaching implications globally, with promotion of sustainable consumption also identified as one of the sustainable development goals (SDGs). Hence, there is a need for relevant information to guide consumer buying decisions. Eco-labels have been created to serve as one of the key communication platforms for this purpose, but studies indicate low levels of comprehension. Hence this paper proposes a conceptual framework using established neuroscience theories and principles to address this topic of significance.

The “Simplicity Principle” propagates that simpler explanations find place over complex ones. Also, the Dual System Theory focuses on the two systems, intuitive System 1 and cognitive System 2, used by the brain to process information. We spotted a research gap here and leveraged these theories and drew from several earlier studies to propose a framework that presenting information in a “simple” manner on eco-labels would accelerate sustainable consumption.

System 1 works to reduce cognitive process and load on System 2, influencing overall choice and purchase decision. System 2 capacity requires the need to minimize cognitive load through processing simpler messages. Quick processing of information by System 1 generates impressions, attention and attitude. Once accepted by System 2, these often remain unchanged unless necessary and invariably turn into beliefs and voluntary action. Simplicity leverages speed and effortless processing ability of System 1, reducing effort of cognition by System 2 and enabling a decision (to purchase “green”).

Sustainability and sustainable consumption are matters of social and environmental concern and significance. This framework proposes the need for policymakers and businesses to consider adopting the “simplicity” approach in promoting sustainable consumption through bridging the vital gap in the understanding of eco-labels by consumers. There are implications and opportunities for researchers to conduct empirical research across different categories to validate this framework.

While several methods have been explored and implemented, given the significance of sustainability and sustainable consumption, eco-labels suffer from lack of comprehension, thus affecting adoption by consumers. Applying fundamental neuroscience principles of “simplicity” seems to have been overlooked so far toward addressing this gap. This framework proposes that applying “simplicity” to stimuli such as eco-labels and communications be considered to address and correct the situation and help to accelerate sustainable consumption.

This paper aims to study the interplay between a risk-averse national brand manufacturer's (NBM) selling mode decision and a risk-neutral e-platform's private brand (PB) introduction decision.

A game theory model is used to solve selling mode decision, that is whether transform the selling mode from the wholesale mode to the marketplace mode, and PB introduction decision, that is, whether introduce the PB.

The results show that for the NBM, under certain condition, the NBM's selling mode decision is not affected by the e-platform's PB introduction decision. High revenue-sharing rate is conducive only when the difference in consumer preference between the PB and the national brand (NB) is small. The NBM's risk aversion will improve the applicability of the marketplace mode. For the e-platform, high PB preference of consumers and risk-averse behavior of the NBM is not conducive to PB introduction. For the supply chain, scenarios that the NB monopolizes the market under the wholesale mode and PB introduction under the marketplace mode should be prevented. PB introduction under the wholesale mode will become the only equilibrium with the increase of risk aversion of the NBM. Finally, the authors extend the scenario that consumers prefer the PB and the e-platform is risk-averse enterprise and find that PB introduction under the wholesale mode is detrimental to the NBM but beneficial to the supply chain. The impact of consumers' PB preference on the e-platform's PB introduction is opposite to the basic model. The impact of the e-platform's risk aversion on game equilibrium is opposite to that of the NBM's risk aversion.

This paper is first to study selling mode decision and PB introduction decision when considering enterprises' risk-averse attitude.

In this paper, the authors study the entry and outsourcing strategies of manufacturer while considering the brand spillover effect resulting from outsourcing. The supply chain comprises two manufacturers: one being the entrant with a strong brand, and the other as the incumbent with a weak brand. The entrant decides whether and how to enter the market.

Stackelberg game is applied to study the optimal strategies for the manufacturers. This paper conducts a comparative analysis on four situations, yielding conclusions and managerial insights.

The results show that, for the entrant, there is no need to worry about the brand spillover effect in the outsourcing process, which is very interesting and counterintuitive. To get further, the authors find the reason: The spillover effect causes the entrant’s equilibrium retail price to grow faster than the wholesale price. They also prove that a stronger brand effect empowers the entrant to challenge industry barriers, while the impact of the brand spillover effect is the opposite. For the incumbent who acts as the weak party in this issue, it is demonstrated that the optimal choice is to continue selling when facing the encroachment and outsourcing call from the entrant.

Differing from previous studies, the authors notice the brand spillover effect caused by outsourcing when studying company’s entry strategy. They further divide the brand effect into two parts, one of which does not exhibit a spillover.

The present study, underpinned by the stimulus-organism-response (SOR) theory, aims to examine the impact of packaging semiotics on brand image, perceived brand quality, brand loyalty and purchase intention of well-established food brands.

A self-administered questionnaire was disseminated to participants residing in the Lucknow region of India. We conducted an experiment in which 374 participants evaluated the factors on a stimulus (chips packaging) using an online survey. Collected data were analysed through structural equation modelling (SEM).

The result suggests that packaging semiotics exhibits a positive influence on brand image and perceived brand quality of consumers. The brand image significantly impacts brand loyalty and consumers’ purchase intention. In addition, the perceived brand quality has a positive significant impact on brand loyalty, but a negative and insignificant influence on purchase intention. The results show that both brand image and perceived brand quality significantly mediate the relation between packaging semiotics and brand loyalty. Brand image significantly mediates but perceived brand quality does not mediate the relation between packaging semiotics and purchase intention.

The results of the study will assist food brands in determining how to utilise semiotics in packaging to positively influence brand image, perceived brand quality, brand loyalty and consumers’ intent to purchase.

The study is unique in the sense that it assesses the role of packaging semiotics as antecedent in mapping of brand loyalty and purchase intention through brand image and perceived product quality. This study takes a lead as these constructs have been less explored relatively from the lens of packaging semiotics in an emerging Asian market.

A meat quality grading system is essential to meet consumers' increasingly diversified demand for food quality in the global market. This study aims to determine the effectiveness of the upcoming Chinese quality grading labels and examine the information effect of labeling standards on pork consumption choices.

Using an online survey with choice experiments, this study estimates consumer valuation for the fat thickness of different pork primal cuts by simulating three scenarios. Generalized mixed logit models in WTP space are used to analyze the choice experiment data.

Chinese consumers prefer lean pork to fatty pork and this preference does not vary significantly between primal cuts. Consumer valuation for ungraded high-quality (lean) pork increases after the implementation of the quality grading. Meanwhile, they are willing to pay high premiums for labeled pork (including level 1, 2, 3), and there are higher premiums for pork with higher levels. Besides, incomplete information on labeling standards could achieve more premiums for pork than relatively complete information.

This study pays attention to essential but few-noticed pork quality grading. The findings provide references for pork industry practices and policy-making of the meat quality grading system in China and globally by examining incomplete and relatively complete information effects on consumer choices.
