Akzeptanz von Informationssystemen durch Schweinemäster: Eine Kausalanalyse 31
Arens, Ludwig; Plumeyer, Cord-Herwig; Theuvsen, Ludwig.
Im Zuge der Anstrengungen, die Verunsicherung der Verbraucher zu beheben, wird auf vielfältige Weise versucht, die Sicherheit von Lebensmitteln zu verbessern. Dabei ist auch der Informationsaustausch zwischen Akteuren in den Wertschöpfungsketten der Agrar- und Ernährungswirtschaft in den Fokus gesetzgeberischer wie auch privater Initiativen gerückt. Neben technologischen Hindernissen, vor allem der fehlenden Kompatibilität von Informationssystemen, lassen sich auch Verhaltensaspekte als Hemmnisse des Informationsaustauschs und der Informationsverarbeitung identifizieren. Das Ziel dieses Beitrags ist es vor diesem Hintergrund, am Beispiel des Tiergesundheitsmanagements in der Schweinefleischwirtschaft Antworten auf die Frage zu geben, welche Einflussgrößen...

Agrifood Certification Schemes in an Intercultural Context: Theoretical Reasoning and Empirical Findings 31
Gawron, Jana-Christina; Theuvsen, Ludwig.
The need for adequate systems to guarantee the quality of food products has become more and more obvious in recent years. As a consequence, not only in Germany but throughout the world, the number of certification schemes has been increasing for nearly a decade. Due to the implementation of these standards in various countries, a considerable number of contingency factors exist that may influence the effectiveness and efficiency of such schemes. These factors include the diverse political, economic and social conditions in the different countries. Numerous studies attribute a decisive role in the successful implementation of management instruments to cultural influences. Cultural conditions may differ considerably from region to region around the world....

Internationalization and Corporate Success - Empirical Evidence from the European Dairy Sector 31
Ebneth, Oliver; Theuvsen, Ludwig.
Increasingly, cooperatives in the agribusiness are being confronted with the globalization of agri-food markets. Cooperatives adapt to this development by internationalizing their activities. This paper presents a method of measuring the degree of internationalization (DoI) and its application to European cooperatives in the dairy sector. Then, the financial performance of these cooperatives is measured by applying balance sheet analysis. The paper ends with a discussion of why German cooperatives are noticeably less internationalized and show weaker financial performance than their European competitors.

Costs of Processing Genetically Modified Organisms: Analysis of the Rapeseed and Corn Industries 31
Gawron, Jana-Christina; Theuvsen, Ludwig.
Die zunehmende Verbreitung gentechnisch veränderter Organismen (GVO) wirft die Frage nach möglichen wirtschaftlichen Konsequenzen auf. Die parallele Existenz von GVO- und GVO-freier Ware im Markt kann mit Kosten- und Nutzeneffekten verbunden sein und spielt somit aus betriebswirtschaftlicher Sicht eine wachsende Rolle für die Unternehmen der Ernährungswirtschaft. Vor diesem Hintergrund wurde im Herbst 2006 eine empirische Studie durchgeführt, um am Beispiel Raps und Mais die Strategien deutscher Lebensmittelverarbeiter im Umgang mit GVO sowie mögliche Zusatzkosten, die sich aus der zunehmenden Verbreitung von GVO ergeben können, zu ermitteln.

RISIKOWAHRNEHMUNG IN MILCHVIEHBETRIEBEN: EINE EMPIRISCHE STUDIE ZUR VERGLEICHENDEN BEWERTUNG VON POLITIK-, MARKT- UND PRODUKTIONSRISIKEN 31
Wocken, Christian; Schaper, Christian; Lassen, Birthe J.; Spiller, Achim; Theuvsen, Ludwig.
Im Zuge der Reform der EU-Agrarpolitik werden seit dem Midterm-Review zunehmend weniger politische Instrumente zur Stützung des europäischen Milchmarkts eingesetzt. Dadurch und durch die wahrscheinlich im Zuge der WTO-Verhandlungen erfolgende Lockerung des EU-Außenschutzes werden Milcherzeuger wesentlich stärker als bisher den Kräften des Marktes und den damit verbundenen Risiken ausgesetzt. Vor diesem Hintergrund war das Ziel der vorliegenden Studie, die Risikowahrnehmung der Landwirte aus einer verhaltenswissenschaftlichen Perspektive zu untersuchen. Datengrundlage bildet eine Befragung von 236 Milcherzeugern zum Risikomanagement auf ihren Betrieben. Dabei wurden Politik-, Markt- und Preis- sowie Produktionsrisiken hinsichtlich ihrer...

Pfadabhängigkeit als Forschungsprogramm für die Agrarökonomie 31
Theuvsen, Ludwig.
More than a decade ago, path dependence turned out to become a promising research program for agricultural economics. This article reviews important trends in path dependence research and highlights its role in the economics of technology, institutional economics, agricultural economics, and organization theory. Due to potential inefficiencies of path dependent processes, more and more researchers focus on path creation which has as yet not been understood very well. The implications of these recent developments for research questions and methodology of agricultural economics are sketched.

More Trust Instead of More Vertical Integration in the German Pork Production? Empirical Evidence and Theoretical Considerations 31
Schulze, Birgit; Spiller, Achim; Theuvsen, Ludwig.
It is often hypothesized that contracts and vertical integration are paramount for the future competitiveness of meat supply chains. In this paper we review empirical evidence and theoretical reflections underlying this argumentation. We confront the contract and integration hypothesis with transaction cost considerations taking into account current technological and institutional developments and results from a survey in German pig production. It is concluded that more trust and commitment in non-contractual long-term relationships may be a viable alternative to stricter vertical coordination in meat supply chains.

The Influence of Clusters on the Competitiveness of Hog Production: The Example of Northwestern Germany 31
Deimel, Mark; Arens, Ludwig; Theuvsen, Ludwig.
In recent decades the northwestern part of Germany (Weser-Ems region) has come to focus on intensive pork production. This has led to public outrage about the disposal of biological waste, farmers’ complaints about the high cost of leasing land, soaring risks of animal diseases, and the decreasing popularity of intensive animal husbandry. However, despite these problems, due to a beneficial cluster structure, the region is a successful market participant. To shed some light on the relationship between network relationships in clusters and competitiveness, an empirical survey was undertaken to compare this pork-intensive region with non–pork-intensive regions. Bi- and multivariate analyses reveal a better access to knowledge and information on the part of...

Food Chain Actors’ Perceptions of and Adaptations to Volatile Markets: Results of a Media Analysis 31
von Davier, Zazie; Heyder, Matthias; Theuvsen, Ludwig.
The volatility of agricultural markets has increased remarkably in recent years. In spite of this, the way in which supply chain actors perceive market volatility has only rarely been analyzed. This paper seeks to close this research gap by presenting empirical findings about how the volatility of agricultural markets is perceived, how increasing market volatilities are being explained, and what adaptations to the volatile external environments are being suggested. Based on a large‐scale media analysis, we have identified perceptions, which vary greatly over time, especially with regard to the perception of the threats and opportunities volatility creates for farms and firms and the most frequently identified reasons for volatile prices.

Perceived Market Risks and Strategic Risk Management of Food Manufactures: Empirical Results from the German Brewing Industry 31
Theuvsen, Ludwig; Niederhut-Bollmann, Christoph.
The food industry is currently facing huge structural changes, such as growing concentration ratios and degrees of internationalization and as well as the reorganizations of food supply chains. Such developments do not only contribute to growing market risks but also require strategic reorientations on the part of food manufacturers. So far, risk management and strategic planning have been two fairly separated theoretical strands. In this paper we blend both schools of thought and analyze food manufacturers' perceived market risks and strategic risk management of food manufacturers. Empirical Our data stem from large-scale empirical research in the German brewing industry.

Regionalwirtschaftliche Effekte veränderter Wassernutzung in Nordost-Niedersachsen 31
Battermann, Henning W.; Bergmann, Holger; Theuvsen, Ludwig.
Mit der Wasserrahmenrichtlinie hat die EU einen juristischen Rahmen geschaffen, alle aquatischen Ökosysteme, zu denen auch die Grundwasserkörper gehören, zu schützen. Diese vornehmlich auf den Wasserschutz abzielende Maßnahme zieht neben klaren Vorteilen für den Wasserhaushalt und die -versorger möglicherweise auch Vor- wie Nachteile für landwirtschaftliche Betriebe wie landwirtschaftlich geprägte Regionen nach sich. Mit dem vorliegenden Beitrag wird untersucht, welche regionalen Effekte eine verminderte Beregnung für eine der am stärksten von Trockenheit betroffenen Regionen Nordostniedersachsen besitzen würde. Mit Hilfe des Regionalmodels „POMMARD“ wurden die regionalen Effekte (a) einer Halbierung des verfügbaren Beregnungswassers sowie (b) eines...

Strategies and Challenges of Internationalisation in BRIC-Countries: Empirical Results from the German Agribusiness 31
Heyder, Matthias; Theuvsen, Ludwig.
The objective of this paper is to identify the strategies and instruments that agribusiness companies currently use to cope with the globalisation of agricultural markets. This aim is achieved by means of presenting the empirical results of an online and telephone survey that was undertaken between April and August 2010 with the participation of 113 German agribusiness firms. The majority of respondents expect that the importance of the markets in the BRIC countries will increase remarkably in the future. For developing international business activities, comparatively simple strategies such as direct and indirect exports via domestic and international traders are most widely used. This may be the result of challenges the agribusiness companies are facing...

Networking in Meat Production Systems: The Influence of Cooperative Structures on Farmers’ Participation 31
Deimel, Mark; Theuvsen, Ludwig.
Against the background of increasing competitive pressures and growing requirements with regard to food quality and safety, the significance of network-wide collaboration in food production has been pointed out in recent years. With this in mind, it is the objective of this paper to analyse pig farmers’ network participation in general and to explore whether cooperative structures in food supply chains influence the type as well as the quality of farmers’ network relations. Our results show that cooperative structures influence pig fattening farmers’ network participation concerning relationship quality with slaughterhouses as well as farmers’ choice of network partners for information exchange and consultancy. Furthermore, the results show that farmers...

Agribusiness Firm Reactions to Regulations: The Case of Investments in Traceability Systems 31
Heyder, Matthias; Hollmann-Hespos, Thorsten; Theuvsen, Ludwig.
Markets for agricultural and food products are characterized by high information asymmetries since producers, processors and retailers are in most cases much better informed about the quality of their products than consumers (Henson/Traill 1993). Often consumers are only at (prohibitively) high costs or not at all able to control important quality criterions such as food safety, nutritional value or region of origin. Such credence attributes can result in market failure due to a lack of credible information in the market (Akerlof 1970). As a result, attempts to protect consumers against food hazards, product adulteration and deception have gained much relevance in food supply chains (Deimel et al. 2008). Besides the more or less voluntary private...

Legitimating Business Activities Using Corporate Social Responsibility: Is there a Need for CSR in Agribusiness? 31
Heyder, Matthias; Theuvsen, Ludwig.
result, enterprises in the agribusiness sector are increasingly exposed to the public eye (Jansen/ Vellema: 2004). The perception of consumers and other stakeholders - which are according to Freeman “any group or individual who can affect, or is affected by, the achievement of the organization’s objectives” - is of growing criticism and risk-consciousness and manifests itself in changed attitudes towards food production (Jäckel/Spiller: 2006; Haddock: 2005). The use of GMO in agriculture, e.g., is regarded to be morally reprehensible (Becker: 1999). The BSE-crisis and other food scares led to growing consumer uncertainty and resulted in decreased meat consumption and in the increasing percentage of outspoken vegetarians and low-meat consumers (von...

Corporate Social Responsibility in Agribusiness: Empirical Findings from Germany 31
Heyder, Matthias; Theuvsen, Ludwig.
The social responsibility of businesses has developed into a highly debated issue in recent years. Especially in agribusiness, recent scandals as well as information asymmetries concerning food production have led to high external pressure on firms from the wider public. Being confronted with a variety of stakeholder goals and relationships, it could be particularly advantageous for enterprises in agribusiness to pursue a corporate social responsibility (CSR) strategy. Based on a literature review, we introduce a conceptual framework that provides insights into the determinants of CSR and its effects, in particular, on the legitimacy and reputation, and finally, the performance of enterprises in agribusiness. This contingency-theoretic approach allows a...

Unternehmerische Netzwerkpartizipation in der Nahrungsmittelproduktion: Ergebnisse einer empirischen Studie am Beispiel des Tiergesundheitsmanagements im Schweinefleischsektor 31
Deimel, Mark; Plumeyer, Cord-Herwig; Theuvsen, Ludwig; Bahlmann, Jan.
In der Netzwerkforschung werden Netzwerke als zentral für zwischenbetriebliche Interaktionen und den Zugang zu Informationen und Wissen gesehen. Von der Einbindung von Betrieben in Netzwerke werden daher erhebliche Auswirkungen auf ihre Wettbewerbsfähigkeit erwartet. In diesem Beitrag werden exemplarisch auf der Grundlage einer großzahligen empirischen Erhebung die Netzwerkbeziehungen deutscher Schweinemäster analysiert und die sich aus der Einbindung in Netzwerke ergebenden Wirkungen auf den Umfang und die Erfolge des betrieblichen Tiergesundheitsmanagements analysiert. Die Ergebnisse stehen nur in Teilen im Einklang mit den Vorhersagen der Netzwerktheorie und deuten auf weiteren Forschungsbedarf, namentlich eine differenziertere Erfassung des...

Heterogeneity in the Evaluation of Quality Assurance Systems: The International Food Standard (IFS) in European Agribusiness 31
Schulze, Holger; Albersmeier, Friederike; Gawron, Jana-Christina; Spiller, Achim; Theuvsen, Ludwig.
Due to the growing demands of customers and several food crises, quality assurance schemes have become increasingly popular in agribusiness. With this trend in mind, it seems worthwhile to take a closer look at the satisfaction of participating European companies. The study focuses on the IFS, which has gained much relevance in the food industry. A questionnaire concerned with perceptions of the advantages and disadvantages of the IFS was answered by 389 companies. The results indicate that the overall evaluation of the IFS is primarily affected by the perceived usefulness of the catalogue of requirements and its evaluation. Furthermore, a cluster analysis was conducted and three clusters were identified, representing heterogeneous evaluations of the IFS.
