Der türkische Tomatensektor: regionale Gesichtspunkte und räumliche Marktintegration

In der Wertschöpfung der türkischen Landwirtschaft hat die Obst- und Gemüseproduktion große Bedeutung und Tafel- und Industrietomaten sind wiederum das wichtigste Einzelprodukt unter den Gemüsesorten. Das Papier beschreibt die Struktur und Entwicklung des Sektors seit den 1990-er Jahren und geht auf die Betriebsstruktur in der Primärerzeugung sowie die Situation in Handel, Verarbeitung und Vermarktung ein. Regionale Spezifika werden herausgearbeitet. Eine Analyse der Struktur und Dynamik von Verbraucherpreisen für Tafeltomaten in 22 Provinzen schließt sich an. Die Frage der Integration der Märkte für Tafeltomaten zwischen Provinzen wird mit Hilfe von Schwellen-Fehlerkorrekturmodellen untersucht, wobei handelsbehindernde Transaktionskosten berücksichtigt werden. Die Analyse der bilateralen Integrationsbeziehungen zwischen 22 Provinzen zeigt, dass entlang den Küsten ein Ring von Provinzen existiert, deren Tomatenmärkte eng mit denen anderer Provinzen verbunden sind, während die untersuchten Provinzen im Landesinneren in dieser Hinsicht relativ isoliert sind. Bei einigen Provinzpaaren findet Preistransmission nur dann statt, wenn Abweichungen vom interprovinziellen Gleichgewicht eine bestimmte Schwelle überschritten haben. -- E N G L I S H V E R S I O N: Tomatoes have the largest share among fruits and vegetables, which add substantially to the gross agricultural product in Turkey. We describe the structure and development of this sector from the year 1990 onwards, covering farms in primal production, trade facilities, processing firms, and marketing channels. An analysis of retail prices for table tomatoes in 22 provinces and their dynamics follows. Finally we employ a threshold vector error-correction model to analyse integration among the markets for table tomatoes in the presence of transaction costs. The results show a ring of integrated provinces along the coasts of Turkey, while the interior provinces are rather separated. In some cases price transmission only occurs when deviations from an interprovincial price equilibrium exceed a certain threshold.Tomatoes,Turkey,spatial market integration,Gemüse,Tomaten,Türkei,Marktintegration,Fehlerkorrekturmodell

Agriculture in the Face of Changing Markets, Institutions and Policies: Challenges and Strategies

Since the late 1980s, agriculture in Central and Eastern European Countries (CEECs) has been under considerable adjustment pressure due to changing political, economic and institutional environments. These changes have been linked to the transition process, as well as the ongoing integration into the European Union and the world market. Reduced subsidies, increased environmental and food quality demands, as well as structural changes in the supply, processing and food retailing sector call for major structural adjustments and the improvement of farmersâ managerial abilities. Though such changes always carry significant threats to farms, they also offer new opportunities for the farms' entrepreneurial engagement. Upcoming changes in the agricultural environment and their possible consequences for farm structures across Europe are thus still timely subjects. The objective of the IAMO Forum 2006 is to contribute to the success of agriculture in the CEECs, as well as their neighboring countries, in todayâs increasingly competitive environment. Concrete questions the conference focuses on are: What are the most suitable farm organizations, cooperative arrangements and contractual forms? How to improve efficiency and productivity? Where do market niches lie and what are the new product demands? This book contains 33 invited and selected contributions. These papers will be presented at the IAMO Forum 2006 in order to offer a platform for scientists, practitioners and policy-makers to discuss challenges and potential strategies at the farm, value chain, rural society and policy levels in order to cope with the upcoming challenges. IAMO Forum 2006, as well as this book, would not have been possible without the engagement of many people and institutions. We thank the authors of the submitted abstracts and papers, as well as the referees, for their evaluation of the abstracts from which the papers were selected. In particular, we would like to express our thanks to OLIVER JUNGKLAUS, GABRIELE MEWES, KLAUS REINSBERG and ANGELA SCHOLZ, who significantly contributed to the organization of the Forum.

Non-Linear Spatial Price Transmission on the Turkish Wheat Market

Agricultural production is spread all over Turkey and the considerably different climatic and topographical conditions among the provinces lead to highly diversified agricultural production. Thus, is it reasonable to assume an integrated market all over Turkey? This paper analyzes the spatial price transmission among 28 Turkish provinces. Applying a bivariate threshold vector error correction model allows to account for transaction costs without having direct information of these. The results suggest that there is an inner cluster of several provinces that can be treated as one large integrated market. However, the degree of market integration decreases in the outer provinces of Turkey. Although transaction costs are significant for nearly all provinces, Ankara clearly stands out, showing transaction costs with every other province. The observed economic variables fail to explain this behavior. Hence, social networks as relevant factor for the interactions on the Turkish wheat market come into play. A band of non-adjustment is only established for a minority of those pairs that show a threshold. Thus, one has to critically assess the applicability of such a threshold model to analyze the market behavior of spatial price transmission
