Consumer willingness to pay for traceable food products: a scoping review

Abstract

PurposeTraceability is an increasingly important tool for reducing food safety risks and managing supply logistics. Given the costs of implementing and maintaining traceability systems, it is crucial to understand consumer willingness to pay (WTP) for traceable products.Design/methodology/approachThe authors conducted a scoping review to collate the existing literature on consumer WTP for traceability in food products to determine the nature of the evidence base and to identify research gaps.FindingsA total of 77 articles were included in the review. The number of studies published per year generally increased over the review period, and China and the United States were the most common countries in which studies were conducted (43.6 and 14.1% of total studies, respectively). All but one of the studies investigated at least one factor that might influence consumer WTP for traceability, the most common of which was socio-demographic characteristics (72.7%). Three-quarters of studies used hypothetical methods to elicit WTP values (75.3%), whereas one-quarter used non-hypothetical methods (24.7%). Most studies included some measure of preference heterogeneity (83.1%).Research limitations/implicationsThere is some potential for systematic bias in the evidence due to the predominance of studies from only a few countries and the possible presence of hypothetical bias. These potential biases could be corrected through future research.Originality/valueTo the authors’ knowledge, no previous study systematically and comprehensively identifies and summarizes the evidence base on consumer WTP for traceable food products.

Consumers’ valuation of blockchain-based food traceability: role of consumer ethnocentrism and communication via QR codes

“…Given the limited number of blockchain-based traceability systems for processed food products, this study is one of the first to empirically prove that consumers are willing to pay a price premium for Feta cheese with blockchain-based traceability information. This finding could encourage food companies to invest in more advanced traceability systems to meet the increasing demand for traceable food products (Vriezen et al. , 2023).…”

“…In theory, consumers can therefore only access the traceability information of direct sellers/retailers and not that of primary producers. In the meantime, recent studies have shown that consumers are increasingly demanding more transparency in agri-food supply chains (Hou et al, 2020;Vriezen et al, 2023). The increased demand for transparency in the food supply chain is motivating food chain actors to utilise more advanced technologies to improve their traceability systems (Latino et al, 2022;Mattevi and Jones, 2016).…”

Experiences Using Ethereum and Quorum Blockchain Smart Contracts in Dairy Production

“…Consumers are increasingly interested in aspects of food production such as use of high-quality, local raw materials, adherence to traditional processing methods, and the preservation of nutritional values [1,2]. However, the complexity of food supply chains and the often inadequate controls by local authorities pose challenges to ensuring food authenticity and the integrity of food systems [3].…”

“…However, the complexity of food supply chains and the often inadequate controls by local authorities pose challenges to ensuring food authenticity and the integrity of food systems [3]. As proven in the literature, the implementation of robust traceability systems can help effectively combat food fraud and provide sufficient communication to consumers about food safety and quality [1,4].…”
