Última Trust in the US‐EU Fruit and Vegetable Chain: Do US Exporters Understand EU Importers? 31 Ameseder, Christoph; House, Lisa; Haas, Rainer; Meixner, Oliver; Fritz, Melanie; Dahl, Ellie; Hofstede, Gert Jan. Research on organizational and inter‐organizational trust has become an important field in management and marketing literature, as it is perceived as a pivotal aspect of business transactions. However, clarifications are still needed on the issue of whom we trust; is the person whom we are trading with trusted, or the organization, or just the product‐quality? Not only has this question not been answered within this field of research, neither have cultural differences have been described to any great extent. Additionally, if the perceived factors important to establish trusting relationships may or may not be the same on the buyers and the sellers side in international business transaction in food chains. The primary objective of this research study...

Ano: 2010 URL: http://purl.umn.edu/100473 Dynamics in trade streams in international food supply networks. The case of fresh produce, meat, and cereals 31 Deiters, Jivka; Fritz, Melanie. The identification of the most relevant agri-food trade streams serves as the foundation and shows the trading volume in selected countries on which the later research of project e-Trust is based, with particular consideration of the specific role of trust in these transactions and its transfer in e-commerce afterwards. For the elaboration of the data collection, mainly the international statistical database of Food and Agriculture Organization of the United Nations (FAOSTAT) is used as a common basis of the comparison. The procedure has been applied to six European traders in agricultural products (Germany, Austria, Italy, Slovenia, Greece and Spain) and three non-European countries (USA, Brazil and Turkey). According to the statistical sources mentioned...

Ano: 2010 URL: http://purl.umn.edu/95022 Short Food Supply Networks: Expectations, Experiences, Trust in the Case of Farmers Markets 31 Fritz, Melanie; Martino, Gaetano. Farmers Markets are receiving an increasing attention by both food chains actors and social scientists. Economic and sociological studies are contributing to the comprehension of these forms of exchange. Both consumers and producers are fostering their expectations about the renewal of a mode of exchange which sustained local production-consumptions linkages. The main economic function of these organizational structures seems to be the reduction of the price paid by the consumers and the enhancements of allocation of farm products. The basic interpretation of these forms of exchange focuses on market structure, nonetheless the exchange relationships seem to emphasize several dimensions, including economic and cultural aspects. The objective of the paper is...

Ano: 2009 URL: http://purl.umn.edu/59192 Collaborative Working Environments in Food Supply Networks 31 Pankiewicz, Maciek; Schiefer, Gerhard; Fritz, Melanie. This paper will discuss the ongoing research in area of conceptualization, design of collaborative working environments and its adoption for food supply networks. There will be a group needs approach for designing such environments presented. Tracking and tracing, agreements on quality policy, improvements in logistics, dissemination of innovations, cooperation in quality planning and market orientation, access to knowledge bases, etc. are all examples which build on an increased horizontal or vertical integration in information and communication activities. For these purposes adoption of collaborative working environments may be of a crucial importance for food supply networks.

Ano: 2009 URL: http://purl.umn.edu/59185 Customer Communication of Regional Quality Efforts: A Case From the Grain Sector 31 Meyer, Christian H.; Fritz, Melanie; Schiefer, Gerhard. Usually, marketing communication efforts in the agrifood sector address the end consumers and concentrate on products that are processed and ready for consumption, thus quality efforts often concentrate on the final product. Moreover, there’s a widespread view that agricultural commodities like wheat aren’t suitable neither for product focused marketing nor branding. However, recent developments in the in agrifood sector challenge this view. The increasing use of biotechnology, the globalisation of markets and changing consumer demands for quality, food safety and process attributes require improved communication concepts and information sharing along whole production chains. This paper considers the development of a quality communication system to support...

Ano: 2010 URL: http://purl.umn.edu/100595 Editorial: Food System Dynamics 31 Fritz, Melanie; Schiefer, Gerhard. The food system involves all actors, activities, resources, and environments that produce and provide food to people wherever they are. It serves basic human needs and is as such of core relevance for human survival. It is global in production, consumption, and environmental impacts. But it is also deeply rooted in the social, cultural, natural, political, and legal environments of society. It needs to serve a diversity of consumer needs and lifestyles and has to cope with an organizational complexity where, a.o. small scale farms or enterprises interact with globally active industry or retail groups and where rural sites of production are remote from the urban and ever growing centers of consumption.

Ano: 2010 URL: http://purl.umn.edu/91145 A multi-level cost benefit approach for regulatory decision support in food safety and quality assurance scenarios 31 Fritz, Melanie; Schiefer, Gerhard. In complex policy decision situations where policy objectives can only be reached through appropriate activities of individual actors with own decision authority and individual objectives, the classical approaches for measuring the effects of regulatory initiatives through cost-benefit or related types of analysis do not provide the appropriate information for decision support. This paper discusses a framework for a multi-level analysis approach that could provide decision support in multi-level policy decision situations.

Ano: 2008 URL: http://purl.umn.edu/44274 Electronic Collaboration Platforms for Communities 31 Pankiewicz, Maciek; Fritz, Melanie; Schiefer, Gerhard. One of the critical success factors for the future development of the agri-food sector is the increased integration of enterprises and other stakeholders in horizontal and vertical ‘communities’. Tracking and tracing, agreements on quality policy, improvements in logistics, dissemination of innovations, cooperation in quality planning and market orientation, access to knowledge bases, etc. are all examples which build on an increased horizontal or vertical integration in information and communication activities. The paper will discuss ongoing research on the conceptualization, design and testing of online communities that provide the functionalities that might improve cooperation in the different (horizontal and vertical) dimensions. It builds on...

Ano: 2008 URL: http://purl.umn.edu/49885 The Role of Trust in Emerging Food Supply Network Relations 31 Fritz, Melanie. The food sector is the largest economic sector in the European Union (CIAA, 2005). It consists of a complex, global and dynamically changing network of trade streams, food supply network relations and related product flows (Fritz, Schiefer, 2008a). Food supply networks are subject to dynamically changing circumstances, which include fluctuations at primary production due to changes in weather or climate, impacting supply and demand and prices, and also impacting the quality of raw material, variations in food consumption due to seasonality or the westernization of diets in Asia (see e.g. OECD-FAO, 2006, Pingali, 2006), the development of alternative uses of raw material such as bio-fuel, and, not the least, from changing attitudes of society towards the...

Ano: 2009 URL: http://purl.umn.edu/59178 Information Reference Models for European Pork Supply Networks 31 Lehmann, Richard J.; Fritz, Melanie; Schiefer, Gerhard. Several global developments such as diminishing production resources, limits in the availability of water and the growing demand for bio-energy as well as sector-wide crises (e.g. BSE, swine fever, dioxin) have led to a changing attitude of society towards the conse-quences of the food system‘s activities for social, economic and environmental issues, cap-tured in the term of sustainability. As a consequence, consumers show increasing interest in the characteristics of food, and in turn, on the availability of related information and guaran-tees. The paper introduces different information reference models for European pork supply networks, which give an aggregated overview about information availability and exchange in the pork sector, identify additional...

Ano: 2011 URL: http://purl.umn.edu/122014 Prioritizing Trust Factors in an Agri-Food B2B E-Commerce Environment 31 Canavari, Maurizio; Rivaroli, Sergio; Fritz, Melanie; Hausen, Tobias. Trust is recognized as an important asset for Business-to-Business e-commerce success, but few studies investigate the link between trust and e-commerce in agri-food markets. This paper aimed at prioritizing some trust factors in e-relationships between actors operating in the agri-food markets. Starting from the results of a previous analysis (Canavari et al., 2005), the importance of three categories namely “share of values and motivations”, “reliability and reputation” and “integration availability and non-opportunistic behavior”, and six trust factors are prioritized using the Analytic Hierarchy Process. The model seems to be capable to assign a priority order to the elements inspiring trust within e-trade relationships in the agri-food chains.

Ano: 2006 URL: http://purl.umn.edu/7773 Supply Chain Management in the Life Science Sector: Does Trust Play a Role? 31 Hausen, Tobias; Fritz, Melanie. Supply chain management has emerged as cross functional, cross company concept to improve coordination of entire value chains through coordinated actions of all companies in the value chain. It has received a major push from the availability of Internet-based information and communication technologies. The conditions in certain sectors are favorable for a realization of chain wide supply chain management. In other sectors, however, conditions are more complex and companies and value chains still struggle to exploit the potentials from supply chain management, in particular when it comes to cross enterprise coordination. This paper takes a complex supply network as example and discusses improvement potentials from supply chain management and developments in...

Ano: 2006 URL: http://purl.umn.edu/7776 Commercio elettronico per la dinamica delle catene agro-alimentari internazionali: un’analisi del potenziale 31 Fritz, Melanie; Canavari, Maurizio; Cantore, Nicola; Deiters, Jivka; Pignatti, Erika. Business-to-business (B2B) e-commerce is an innovative use of information and communication technologies and refers to the exchange of goods and related information between companies supported by Internet-based tools such as electronic marketplaces (also called electronic trade platforms) or online shops. It provides opportunities for cost-efficiency in supply chain management processes and access to new markets. With regard to the food sector with its chain levels input – agriculture – industry – retail – consumer, B2B e-commerce would take place in the exchange of food products between all levels except retail to consumer (business-to-consumer e-commerce). It is evident and widely known that B2B e-commerce brings key advantages and potentials for...

Ano: 2008 URL: http://purl.umn.edu/42891 The Role of Trust in European Food Chains: Theory and Empirical Findings 31 Fritz, Melanie; Fischer, Christian. In Europe, consumer trust in food has become one of the most important factors for the stability of the food sector. An essential prerequisite for the ability to communicate the trustworthiness of food to consumers (B2C) is the creation, maintenance, and communication of trust between companies across the entire food value chain (B2B). For the management and preservation of trust in food chains it is important to know whether differences occur across European countries or whether distinct product chains show variations regarding trust. Based on a survey in five European countries with 747 respondents, this paper assesses the current level of trust between companies together with its influencing structural factors in European food chains and determines...

Ano: 2007 URL: http://purl.umn.edu/8185 Trust and Risk in Business Networks: Towards a Due Diligence for Electronic Commerce 31 Fritz, Melanie. This paper develops a due diligence for electronic transactions with new partners in business networks with complex goods such as food products to enable the use of e-commerce potentials in first time transactions. The e-commerce due diligence is a means to reduce perceived risks and uncertainties for businesses and create trust and confidence in the electronic transaction with appropriate information. The paper presents a conceptual framework for the due diligence integrating the principles of transaction decision making and the four phases of a transaction process. The operationalization of the framework assigns trust signals and control elements to the four process phases to be communicated during the process.

Ano: 2006 URL: http://purl.umn.edu/7753 Trust and Control Dynamics in Agrifood Supply Networks: Communication Strategies for Electronic Transaction Environments 31 Fritz, Melanie; Hausen, Tobias. Agrifood supply networks are dynamic structures where firms regularly face the need to search for new market partners. A decision for a transaction with a new partner requires the existence of appropriate control and safeguard mechanisms as well as trust to overcome perceived risk and uncertainties. Electronic transaction environments offer new potentials for the identification of new transaction partners. However, trust and control need to be communicated appropriately in electronic transaction environments for agrifood supply network scenarios. Problems for appropriate communication are posed by the complex interrelation between trust and control in transaction processes and their dynamically changing importance in a transaction relation.

Ano: 2006 URL: http://purl.umn.edu/25509 MANAGEMENT OF PERCEIVED RISKS IN E-BUSINESS FOR EFFICIENT FOOD SUPPLY NETWORK MANAGEMENT: THE CASE OF TRUST 31 Fritz, Melanie; Canavari, Maurizio. Vertical coordination in food networks is characterized by dynamically changing supply and marketing relationships. E-business provides support and improvement options for vertical coordination processes and flexible supply chain management in food networks. However, adoption of e-business in food networks is low as available e-business offers as the communication of safeguards for trust and control as basis for the transaction decision is not realized appropriately. This paper analyzes decision preferences for trust generation as basis for the design of e-business environments for supply chain management in food networks. The analytic hierarchy process is applied to prioritize preferences for different transaction scenarios in food networks.

Ano: 2007 URL: http://purl.umn.edu/7605 Trust and Electronic Commerce in the Agrifood Sector. A Trust Model and Experimental Experiences 31 Fritz, Melanie; Hausen, Tobias; Schiefer, Gerhard; Canavari, Maurizio. Opportunities coming from electronic commerce provide interesting support options for the Agrifood sector. However, due to the product specific information asymmetry in the agrifood sector, the anonymity of the medium creates a lack of trust increasing transaction costs to engage in e-commerce. This paper develops a trust model for electronic commerce in the agrifood industry allowing for the analysis of trust determinants in traditional agrifood transaction relationships and their transfer to appropriate trust determinants in the e-commerce environment. First experimental results validating the suitability of the model to derive appropriate electronic trust generating elements for a given agrifood transaction environment are presented.

Ano: 2005 URL: http://purl.umn.edu/24742 Information Modelling for Quality and Sustainability 31 Lehmann, Richard J.; Reiche, Robert; Fritz, Melanie; Schiefer, Gerhard. The food sector is confronted with a growing number of public and private requirements, which call for provision of information about the quality and sustainability of food, such as, e.g., its origin, safety and production conditions. This forces enterprises to innovate towards demand driven and knowledge-based production of food. As a consequence, intra- and inter-enterprise production and information processes have to be integrated and suitable information systems need to be developed to provide information for related decision processes. The present paper introduces a generalized modelling framework for model-based decision support systems (DSS) involving production and information processes across whole supply networks. The different phases of a...
