This paper aims to examine the level of economic efficiency and factors that influence economic efficiency among seed potato producers in South-western Uganda.

The paper analyses the economic efficiency of 499 informal and 137 formal seed producers using primary data collected through a structured questionnaire. A multi-stage sampling technique was used to select the study sites and specific farmers. A one-step estimation procedure of normalized translog cost frontier and inefficiency model was employed to determine the level of economic efficiency and the influencing factors.

The results showed that mean economic efficiencies were 91.7 and 95.2% for informal and formal seed potato producers, respectively. Furthermore, results show significant differences between formal and informal seed potato producers in economic efficiency at a one percent level. Market information access, credit access, producers' capacity and experience increase the efficiency of informal while number of potato varieties, market information access and producers' experience increase economic efficiency for formal counterparts.

Most seed potato producers, especially the informal ones do not keep comprehensive records of their production and marketing activities. This required more probing as answers depended on memory recall.

Future research could explore panel data approach involving more cropping seasons with time variant economic efficiency and individual unobservable characteristics that may influence farmers' efficiency to validate the current findings.

The paper shows that there is more potential for seed potato producers to increase their economic efficiency given the available technology. This has a direct implication on the economy through increased investment in the production and promotion of high yielding seed potato varieties to meet the growing national demand for potatoes.

The paper bridges the gap in literature on economic efficiency among seed potato producers, specifically in applying the normalized translog cost frontier approach in estimating economic efficiency in the context of potato sub-sector in Uganda.

This paper aims to investigate how producers of biodynamic and sustainable wine portray their brand identity online.

The study uses an inductive approach to qualitative content analysis of wine producers’ websites. The authors use a theoretical starting point based on the categorizations literature related to institutional scripts and identity projection.

Producers adopt identity templates similar to the provenance and glory templates established in extant research. They demonstrate templates of community, quality, spirituality and sustainability, but there is a break in the templates, and they adopt a pseudo-rationalist template, avoiding detailed descriptions of practices and underpinning philosophy, leaving any references to them opaque and ambiguous. This may be due to concerns over scientific skepticism or spiritual suspicion, or anticipation of a lack of consumer knowledge.

The geographical location of the sample poses limitations to the results of the study. However, the study provides an examination of the nuances of self-categorization as it relates to identity projection, prompting further investigation into its positive and negative potential.

Research on the connection between quality perceptions and experience and credence attributes suggests producers should do more to emphasize the philosophy underpinning biodynamics.

The study contributes to research on marketing for inherently sustainable producers who may suffer potential negative reactions in general and biodynamic wine producers in particular. This study provides nuance to the understanding of negative reactions to novel and innovative wine production practices.

Much has been written on the effect of fast-moving business environments on organizational and supply chain (SC) management. Yet, empirical findings on the effect of changing external and internal contingencies on today’s globalized agrifood SC networks and performance are still fragmented into different organizational instruments, with some conflicting results remaining unexplained. This study aims to address these deficiencies by providing a comprehensive research framework to investigate how SC external and internal contingencies jointly influence organizational SC network structures and agrifood performance across mutually dependent tiers.

Using partial least squares structural equation modeling, the so-called “contingency–netchain–performance” framework, based on contingent resource-based theory and the netchain approach, was empirically tested on data obtained from a standardized survey of 405 artisanal producers and 238 processors in the Nigerian shrimp sector.

The results provide statistical evidence that supports the path dependency of firm performance from the interplay of vertical, horizontal and lateral relationships and, primordially, from both external and internal contingencies. The findings show that the contingency paradigm of fit among small-scale food producers and processors cuts across tiers and uncover a tendency to adopt relational governance and tighter network structures that result in an organic organization as the best-fitting structure.

The paper presents a new research framework that offers comprehensive empirical explanations for the joint influence of SC external and internal contingencies on organizational SC network structures and performance across mutually dependent agrifood tiers. This study’s conceptual, practical and policy implications for SC management provide a nascent and flexible basis on which to identify the best-fitting organizational strategies that maximize firm performance across agrifood SC tiers characterized by changing business environments.

To study these issues, the authors chose a GFSC with one producer and one material supplier as research object, the supplier will offer green material to the producer and the producer will make green food using green production technology. Then, the authors proposed that consumers' perceived value was determined by the trustworthiness levels of the related green and quality-safety information provided by the supplier and the producer. Then, considering the trustworthiness levels of the green and quality information provided by the supplier and the producer, the authors improved the demand function. Afterwards, we constructed four investment models and their income models are built and then a cost-sharing and revenue-sharing contract (hereafter, CSRS) was adopted to coordinate the GFSC.

With the growth of consumers environmental awareness and life level, consumers' requirements for green and high quality food are growing. In recently years, to increase consumers' perceived trustworthiness on the product greenness and quality levels, stakeholders in green food supply chain (hereafter, GFSC) start to adopt the blockchain-based traceability system (hereafter, BLTS). For investors, they need to know the investment conditions and how to coordinate the GFSC.

(1) When the revenue-sharing coefficient is less than three-fourths and higher then a certain vaule, the cost-sharing and revenue-sharing contract can make the GFSC coordinate. (2) The investment cost threshold of the BLTS has a positive relationship with the trustworthiness improvement levels of the green and quality information, the green degree of food products and the quality of food products. (3) In the proposed four investment situations, as the growth of consumers perceived credibility coefficient about the greenness information and the quality information, chain members' revenues will increase. In addition, comparing with co-investing the BLTS, benefits of chain members are lower than them in the sole investment model.

(1) The demand function we proposed can help chain members forecast market demand to support production or ordering decisions. (2) The investment decision policies can offer a theoretical reference for chain members to use the BLTS. (3) The CSRS will offer the theoretical reference for coordinating the supply chain after using the BLTS. Furthermore, our study method can be referenced by other scholars. (4) The study method can offer a method reference for researchers who do a similar discussion in a manufacturing supply chain. Although, our research cannot guide the industrial practices, it can serve as a reference of the similar research in industry.

This study aims to identify the price determinants of fine wines in a small and competitive market. These characteristics are found in many lesser-known wine-producing countries and are often difficult to analyse because of lack of data.

This study hand-collects and transcribes wine-related data for 149 Swiss wineries and 2,454 individual wines over the period 2014–2018 directly from wine lists provided by wineries. This study uses multivariate ordinary least squares regressions to analyse the relation between wine attributes and prices and to assess the effect of a currency shock caused by the sudden appreciation of the Swiss franc in 2015 as well as a reduction in information asymmetries induced by the novel coverage of Swiss wines by The Wine Advocate.

Prices mainly depend on collective reputation, production techniques and product positioning. Surprisingly, following a sharp appreciation of the Swiss franc, producers did not reduce prices. The arrival of a highly influential wine expert on the market also had a positive price effect on rated wines and producers. Both hint at wineries attempting to position themselves relative to competitors.

Few studies examine the price drivers in lesser-known wine markets, where competition is fierce. This study’s results show that wine pricing differs from other more famous and larger wine regions. In addition, to the best of the authors’ knowledge, this study is also the first to analyse the impact of a currency shock and a reduction in information asymmetries on wine prices.

Intermediate short food supply chains (SFSC) have been presented as a possible solution to unsustainable global food supply chains. There is currently a knowledge gap about intermediate SFSC. Thus, this review synthesizes the available literature to identify prominent themes and their main considerations.

This research is based on a systematic literature review including peer-reviewed journal articles until December 2021. Inductive data coding resulted in the identification of four themes related to intermediate SFSC.

The identified themes illustrate the complex landscape intermediate SFSCs operate in and focus on the key relationships within these supply chains. The established relationships have implications for the governance of intermediate SFSCs. The organization of intermediate SFSCs affects numerous sustainability indicators.

Future research should focus on the position intermediate SFSCs have in food systems and the roles intermediaries have in intermediate SFSCs. There is furthermore an opportunity for researchers to investigate different types of intermediaries and explore the factors influencing them.

Creating sustainable food supply chains is one of the major societal challenges of today. The current state of the art suggests that intermediate SFSCs could play an important role in achieving this. So far, this area is underdeveloped and this review highlights knowledge gaps in the literature and suggestions for a future research agenda are proposed.

The purpose of this paper is to investigate how open, mediatised conflict in geographical indications (GIs) can provide the basis for differentiation strategies for heritage producers based on both functional and symbolic benefits.

Longitudinal case study based on multiple data sources, which reconstructs the history of the Bitto GIs and the conflict between the Protected Designation of Origin Bitto Consortium and a small number of heritage Bitto producers.

The paper highlights how the mediatised narration of conflict can contribute to raise consumer awareness, differentiate products and result in symbolic value creation.

Extreme case study design purposively chosen as characterised by conditions likely to accentuate conflict.

The paper develops a conceptual framework that permits to identify the potential for conflict inside GIs. It also contributes to a better understanding of the image of products protected by GIs and the role played by heritage producers. It also offers practical advice on two promotional tools, namely, trade fair participations and experiential showcases.

The paper offers practical advice on the safeguarding of small producers localised in cultural epicentres inside GIs.

The authors introduce the notions, such as competitive wars and secession, that contribute to a better understanding of centripetal/centrifugal forces inside GIs. The authors also propose a better understanding of image creation of GIs, grounded in cultural work in marketing and consumer research.

This paper aims to explore how and in what context adaptive governance might work in practice in relation to climate variability through the study of two successful agri-environmental programs.

Data were obtained through semi-structured qualitative interviews with key policy informants as well as rural agricultural producers. The adaptive attributes of two successful agri-environmental programs with a proven track record in reducing vulnerability and increasing adaptive capacity of rural producers were studied, including program responsiveness, program framing, stakeholder engagement mechanisms, and the respective roles of key actors.

The adaptive governance practices of program delivery through localized government personnel and organizations increased perceived responsiveness. Mechanisms of program delivery and stakeholder participation and review changed over time as well as the framing of programs. Producers and key policy informants agreed that producers responded to concretely framed issues. A possible disconnect was discovered in the anticipated role of government in relation to meeting and responding to the climate change challenge.

This research shows a need to study changes in programs over time in relation to the attributes of adaptive management. Differing climatic events, geographies, and government and stakeholder priorities all contribute to changes in the institutional design of programs and policies.

This paper documents adaptive governance practices in relation to two agri-environmental programs that have successfully facilitated producer adaptation to climate variability in the past, as well as the perceptions of agricultural producers of the future role of government in relation to responding to climate change.

The purpose of this paper is to advance our understanding of the links between the representativeness of the local community by those drafting and elaborating the specification of the geographical indication (GI), the market access and the use of the GI.

The present study followed a comparative research design, building upon primary data from the field works dealing with the elaboration and development of GIs worldwide, from legislations on the protection of GIs and from secondary data, i.e. literature dealing with the elaboration of the GI specifications at case level or national/international level.

The GI is permeable to a multitude of objectives and the management of controversies represent the “price of participatory democracy”, which still needs to be under the umbrella of the justice of peace, the State authority. Representativeness does not necessarily conduct to equity and fairness. It depends on the heterogeneity of the value chain, which might lead to the dilution of the GI specificity. Mandatory membership might not be always the best option Transparency to guarantee the producer’s group works for the common good is essential.

The controversies in the elaboration of the GI product specification are directly induced by the controversies in the management of the GI either by the collective organisation of producers or by the public authority. Issues such as representativeness, mandatory membership, transparency and heterogeneity of the value chain are deeply analysed to understand the functioning of GI producers associations and their limits. The state intervention as justice of the peace appears necessary.

In heterogeneously segmented markets, collaborating with product users in product innovation is important for business success. End user innovators and embedded user innovators differ in terms of their prior embeddedness in the target industry. The purpose of this study is twofold. First, the authors empirically compare these two types of user innovators in terms of their diffusion channel selection. Second, the authors analyze how the technological advances of their innovations affect this difference.

Using an online questionnaire survey, this study collected a sample of 237 user-generated innovations in Japan and analyzed several hypotheses using quantitative statistical approaches.

The analysis shows that embedded user innovators are more likely than end user innovators to transfer their innovations to producers rather than peers. As the technological advances of their innovations increase, end user innovators' likelihood of transferring their innovation to producers increases more significantly than that of embedded user innovators.

This is the first paper to investigate the difference between end user innovators and embedded user innovators with respect to their diffusion channel selection as well as the moderating role of technological advances. The findings bring new perspectives to the domains of user–producer collaboration and technology transfer.
