Última Expectations, Experiences, Trust in the Case of Short Circuit Food Supply Networks AgEcon Martino, Gaetano; Fritz, Melanie. 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 seems to emphasize several dimensions, including economic and cultural aspects. The objective of the paper...

Ano: 2010 URL: http://purl.umn.edu/100592 Information Modelling for Quality and Sustainability AgEcon 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...

Ano: 2009 URL: http://purl.umn.edu/59197 Developments and Development Directions of Electronic Trade Platforms in US and European Agri-Food Markets: Impact on Sector Organization AgEcon Fritz, Melanie; Hausen, Tobias; Schiefer, Gerhard. Electronic trade platforms support trading transactions between enterprises. They have entered the business landscape including the agri-food sector only a few years ago. However, there already have been dramatic changes in the agri-food sector’s platform infrastructures. This paper analyzes developments in electronic trade platform infrastructures in the agri-food sector of the US and Europe between 2000 and 2002 and identifies development strategies of successful platforms. Of 85 platforms in existence in the year 2000, only 25 remained active in 2002. But there are still market entries of new platforms and existing platforms form various types of partnerships. The analysis could identify a range of strategic development lines of successful platforms....

Ano: 2004 URL: http://purl.umn.edu/8146 Perceived risks in cross-border transactions in agri-food chains AgEcon Ameseder, Christoph; Canavari, Maurizio; Cantore, Nicola; Deiters, Jivka; Fritz, Melanie; Haas, Rainer; Matopoulos, Aristides; Meixner, Oliver; Vlachopoulou, Maro. Nowadays, agri-food chains are more global than ever and are characterized by increased imports and exports and global sourcing of products, resulting in increased cross-border transaction risks. The objective of this paper is to identify the typical risks regarding agri-food supply chains involved in cross-border transactions and to assess their importance as perceived by agri-food managers. The analysis takes into consideration four different agrifood value chains (meat, grain, olive oil, fresh vegetables and fruits). Following an explorative approach and a qualitative technique, a series of face to face in-depth interviews was conducted. Results indicate that risk perception may be quite different across countries, value chains, tiers of the supply...

Ano: 2009 URL: http://purl.umn.edu/57659 The Challenge of Reaching Transparency: ‘T-readiness’ of Enterprises and Sector Networks AgEcon Fritz, Melanie; Schiefer, Gerhard. Discussions on the safety and quality of food as well as growing interest in the sustainability of the production, distribution and consumption of food have contributed to the emergence of ‘transparency’ as a critical success factor for the food sector. However, reaching transparency for different stakeholders from different backgrounds and cultural identities is a dynamic process which depends on certain capabilities of enterprises and organizations along the food value chain but also on the realization of a fitting communication scheme within the sector. This discussion asks for the identification and utilization of an indicator that could identify deficiencies and support enterprises and the sector in reaching a level of transparency that could serve...

Ano: 2010 URL: http://purl.umn.edu/97020 Electronic Collaboration Platforms for Communities AgEcon 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 Trust and Electronic Commerce in the Agrifood Sector. A Trust Model and Experimental Experiences AgEcon 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 Customer Communication of Regional Quality Efforts: A Case From the Grain Sector AgEcon 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 Commercio elettronico per la dinamica delle catene agro-alimentari internazionali: un’analisi del potenziale AgEcon 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 Risk Analysis in Selected European and International Food Chains AgEcon Ameseder, Christoph; Haas, Rainer; Fritz, Melanie; Schiefer, Gerhard. The purpose of this study is to assess and evaluate the most important risks in selected European and international food chains from the perspective of the buying company. The primary objective is to identify the “non-acceptable” risks in terms of damage potential and likelihood of occurrence of value chains in the sectors grain, meat, fruit and vegetable, and olive oil. Data was collected by each partner of the European research project “e-trust” (FP6-CT-2006-043056) by conducting 81 qualitative expert interviews with business leaders in Europe (Austria, Germany, Greece, Italy, Slovenia, Spain) as well as in Brazil, Turkey, and the USA. The study focuses on a wider supply chain or network perspective for the risk assessment. Methodically the assessed...

Ano: 2009 URL: http://purl.umn.edu/58708 Trust and Control Dynamics in Agrifood Supply Networks: Communication Strategies for Electronic Transaction Environments AgEcon 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 AgEcon 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 Information Reference Models for European Pork Supply Networks AgEcon 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 SUSTAINABILITY IN FOOD NETWORKS AgEcon Fritz, Melanie; Schiefer, Gerhard. Sustainability in food networks has become a dominant issue in the development of the food sector in light of the challenging scenarios one might expect in the future. Products, enterprises, chains, consumers, and regions are all affected by this discussion. Environmental, social and economic pressures require the development of strategies on how to best meet the challenges and to move the sector with its global presence and its many SMEs towards a status which is sustainable and robust enough to remain so even if future scenarios might deviate from today’s expectations (dynamic sustainability). The paper outlines a framework for research on sustainability developments, sustainability assessments, consumer communication, and the transition of enterprises...

Ano: 2008 URL: http://purl.umn.edu/52648 Supply Chain Management in the Life Science Sector: Does Trust Play a Role? AgEcon 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 Dynamics in trade streams in international food supply networks. The case of fresh produce, meat, and cereals AgEcon 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 The Role of Trust in European Food Chains: Theory and Empirical Findings AgEcon 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 Prioritizing Trust Factors in an Agri-Food B2B E-Commerce Environment AgEcon 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 A multi-level cost benefit approach for regulatory decision support in food safety and quality assurance scenarios AgEcon 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 Editorial: Food System Dynamics AgEcon 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.
