	abstract = {The objective of the paper is to develop an analytical tool that is capable of modelling decision-making in coopetitive business relationships. Managers in the same industry differ in respect of their willingness to adopt coopetition. To better understand coopetitive decision-making, we need a model whereby such decisions can be experimented with and analysed. An important prerequisite of such a model would be its capacity to measure the performance consequences of coopetitive interactions at both firm and relationship levels. We show that existing operationalisation has limited capacity to do that. Based on existing game theoretical constructs, we propose a new operationalisation of a coopetitive decision-making episode in horizontal business relationships using a two-step sequential game. We suggest developing what we term a “coopetitive composite solution matrix” by summing up the payoff functions of the two steps of the game. The suggested operationalisation has the capacity to measure all the potential performance consequences of a complex piece of coopetitive decision-making in an episode. In this way, the decision problem’s cognitive representation becomes straightforward and analysis of the impact of the behavioural attributes of managers on the actual decision-making process is unambiguous.},

Through a comprehensive bibliometric analysis of 438 documents from the Web of Science (WoS) and SCOPUS databases, key research streams within AFSC literature are identified. The study highlights how digitalisation enhances efficiency, traceability, and sustainability, while also presenting challenges such as technological barriers and cybersecurity risks. Complementing the literature review, 24 interviews were made with AFSC members and stakeholders (including raw material producers, processors, manufacturers, retailers, logistic service providers and trade associations) to provide practical insights into the adoption and impact of digital solutions. The findings underscore the necessity for tailored digital strategies across different AFSC sub-sectors, emphasizing the role of digitalisation in improving operational resilience and sustainability.},

This study synthesizes existing literature to identify the key challenges of employment in the agri-food sector in developing countries. 17,125 articles were identified in the Scopus database and based on a two-stage systematic review of 173 articles (final database), six principal topics were identified and analyzed: (1) family farms; (2) special characteristics of employment; (3) gender disparities; (4) wages; (5) education; (6) productivity. Each segment provided important results. Family farms were found to be crucial for employment, production, and income generation in developing countries. The special characteristics of employment often involve migration and mobility challenges, while gender inequalities persist due to the special nature of production. Agricultural wages are lower compared to other sectors, further accelerating outmigration. Education plays a key role to adopting advanced production methods, but educated people often find better opportunities outside the sector. Finally, productivity is crucial in income generation and is often driven by mechanization. These six segments are interconnected, with education emerging as a key factor. This study contributes to the existing literature by providing a systematic and comprehensive synthesis of the employment challenges in the agri-food sector of developing countries and providing targeted insights for policymakers to address pressing issues such as gender inequality or low agricultural productivity.},

	abstract = {Purpose: The study’s purpose was to analyse the use of supplier codes of conduct as a supply chain governance tool and show that such codes can contribute to transparency in supply chain networks by helping define objectives and promote environmental, social and governance (ESG) developments. Design/methodology/approach: The study involved examining 67 publicly available and randomly selected supplier codes of conduct of manufacturing companies from the electronics, vehicle manufacturing, healthcare and food sectors. Findings: Supplier codes of conduct reflect the increasing complexity of social and environmental requirements while maintaining the ethical standards. Reactions to new challenges can be identified in the content of the codes. Many codes expect active development by suppliers and the communication of expectations to lower-tier suppliers. For setting environmental objectives, standards are important; the most influential reference point for the social elements of codes is recommendations from international organisations, while for ethical instruments, it is national legislation. Codes and related information can thus be an instrument for promoting ESG objectives and governance-related transparency in well-defined supply chains and a part of legitimacy-building efforts associated with a wider group of stakeholders. Industry-level differences are identified. Originality/value: Recent literature does little to explore the role of codes of conduct in increasing transparency in supply chain governance and legitimacy efforts. This study contributes by constructing a research framework that helps investigate whether corporate codes of conduct make the activities of supply chain stakeholders more transparent and by providing evidence that companies are actively communicating with a wide range of stakeholders. © 2024, Emerald Publishing Limited.},

	abstract = {Low-carbon hydrogen is a promising option for energy security and decarbonization. Cooperation is needed to ensure the widespread use of low-carbon energy. Cooperation among hydrogen supply chain (HSC) agents is essential to overcome the high costs, the lack of infrastructure that needs heavy financial support, and the environmental failure risk. But how can cooperation be operationalized, and its potential benefits be measured to evaluate the impact of different allocation schemes in low-carbon HSCs? This research works around this question and aims to analyze the potential of cooperation in a generalized low-carbon HSC with limited and critical resources using systems and cooperative game theory. This work is original in several aspects. It evaluates cooperation effects under different benefit allocation schemes while considering infrastructure agents’ dependencies (production, transportation, and storage) and specific traits. Additionally, it provides a transparent, replicable methodology adaptable to various case studies. It is highlighted that HSC coalitions form hierarchies with veto power, pursuing common goals like maximizing decarbonization and demand fulfillment. A cooperative game theory toolbox is developed to evaluate, display, and compare the results of six allocation solutions. The toolbox does not aim to determine the best allocation scheme but rather to support smart decision-making in the bargaining process, facilitating debate and agreement on a trade-off solution that ensures the viability and achievement of long-term coalition goals. It is built on three naïve and three game-theoretical allocation rules (Gately, Nucleolus, and Shapley value) applicable to peer group games with transferable utility. Results are presented for an 8-agent low-carbon HSC along with the total environmental benefit, the allocated individual shares, and numerical indicators (stability, satisfaction, propensity to disrupt), reflecting the acceptability of allocations. Numerical results show that the Nucleolus achieves the highest satisfaction among stable allocations, while the Gately allocation minimizes disruption propensity. Naïve rules yield different outcomes: “equal distribution for producers” carries the highest risk, whereas “equal shares for all agents” and “proportional to individual benefits” rules are stable but perform poorly on other criteria. © 2025 The Authors},
