  Introduction: This study investigates local food producers’ economic sustainability by examining the impact of six variables: external and internal barriers, the number of economic operators, the imbalance of power, the number of distribution options, and waste. Methods: The investigation uses mixed methods of questionnaires and interviews. The data was collected using a self-completed questionnaire, which was answered by 57 local food producers across Norway, and four semi-structured interviews with professionals in the food industry. The quantitative data was analyzed with the use of partial least squares structural equation modeling (PLS-SEM), and the qualitative data was analyzed using a thematic analysis. Results: The study has statistically confirmed three out of eight hypotheses. The three hypotheses show that when the number of economic operators in the supply chain increases and also imbalances in the sales channels increase. Additionally, the imbalance of power in the sales channels has a negative effect on economic sustainability, and external barriers have a negative effect on the imbalance of power in the sales channels. The interviews supported seven of the hypotheses, although four of them were not supported. Discussion: The empirical evidence presented in this study indicates that the lack of balance within the supply chain exerts a substantial influence on the economic sustainability of local food producers. By adopting a comprehensive approach, this research demonstrates that a more holistic perspective leads to enhanced economic sustainability. Additionally, it elucidates the diverse ways in which various factors impact the economic sustainability of local food produce.

  This paper examines the factors which influence sharing of the strategic information (in other words, electronic coordination) in a buyer–supplier dyad. The antecedents of this coordination are examined rather well in the transaction cost economics (TCE) theory and resource-dependency theory (RDT), while the supply chain management perspective is contemplated. The mentioned frameworks are used in the analysis. However, the research focus is narrowed down to the exploration of the antecedents of information exchange conducted via inter-organisational information systems (IOS). The empirical analysis is based on 198 observations of Norwegian companies operating in different types of industries. A regression model is used to test the hypotheses about the antecedents of strategic electronic coordination. The research results indicate that the direct effect of the supplier-specific investments in the IOS on the exchange of strategic information in the buyer–supplier dyad is not statistically significant. The supplier-specific investment in the IOS becomes positively associated with the strategic information exchange in the buyer–supplier dyad only when the buyer is dependent on the supplier. The buyer dependency creates a high motivation for the company to exchange the strategic information with the supplier who is more powerful in the dyad. This research concludes that the companies making substantial investments in the IOS for electronic coordination purposes may not reach their goals if relation-specific factors, such as buyer dependency, are not comprehensively considered. Keywords: buyer dependency, inter-organisational information system (IOS), resource dependency theory, strategic electronic coordination, specific IOS investment, transaction cost economics (TCE)

  In this paper, we attempt to explain how the ownership mechanism of an interorganisational information system (IOS) may impact strategic information exchange (electronic coordination) induced by specific investments in the IOS. Recent research and practice show that heavy investments in IOSs demonstrate mixed results with respect to their impact on the electronic coordination. Consequently, the search of additional factors is needed to help and explain under what circumstances the IOS investments for strategic purposes become beneficial for the companies in a buyersupplier dyad. Transaction cost economics (TCE) and the hostage model are used as a framework for the research. 198 observations of Norwegian companies in different branches of industry constitute the base of the empirical study. A buyer-supplier dyad is the unit of the analysis. A regression model of the relation between the IOS ownership mechanism and the strategic information sharing is used to test two hypotheses about the buyer-supplier collaboration via an IOS. The results demonstrate that the risk of unilateral specific investments in an IOS made by the buyer or the seller is attenuated by the ownership mechanism of the IOS. The willingness of a buyer to share their strategic information with the supplier via the IOS increases if the supplier invests in the IOS which is owned and controlled by the buyer. Conversely, the supplier becomes motivated to share certain sensitive strategic information with the buying company if the latter invests in the IOS which is owned and controlled by the supplier. Keywords: hostage model, inter-organisational information system (IOS), IOS ownership, specific IOS investment, strategic electronic coordination

  Purpose of this paper The paper aims to develop the concept of asset specificity that is the key one in transaction cost economics (TCE). The article explores the inter-organizational issues related with the deployment of Enterprise Resource Planning (ERP) systems in the buyer-supplier dyad. Design/methodology/approach The absence of commonly agreed definition and operationalization of asset specificity construct provides the motivation of this review article. ERP systems as the most indemand information system (IS) are suggested to be considered as specific asset deployed within the buyer-seller dyad. Literature review has been fulfilled to find out what types of asset specificity are relevant to ERP systems and how this specificity could be measured. Two interviews with the vendor of ERP systems (SAP authorized agent in the Republic of Belarus) have been conducted to support the findings. Findings ERP systems possess mostly the traits of procedural asset specificity. Heavy investments in personnel training, efforts to explore the supplier’s business processes and to establish seamless information flow between the companies make the investments in ERP highly specific for the particular buyer-seller relationship.
