“The total vegetables, produced over the infinite plain, would be in‐
finite; but after transport cost, only a finite amount will get through
to any inner radius“
Paul A. Samuelson (1983, p. 1480) using a highly stylized counter‐
example to refute the general supposition that goods with high
transport rates are always produced close to the centre of demand
and vice versa.

Acknowledgements
A number of people have to be mentioned here for their support at various stages of the study.
First of all, I express my sincere gratitude to my supervisor, Prof. Dr. Hermann Waibel, who has
attracted my interest for the topic and continuously supported the work throughout the gesta‐
tion of this thesis. His guiding advice and constructive cricitism have been invaluable. I also
thank Prof. Dr. Javier Revilla Diez for his readiness to act as a second referee.
During the data collection in Thailand, I had to rely on the help of many persons, who have
been extremely supportive and patient. First of all I thank all farmers who were ready to share
their knowledge about vegetable production in field interviews and expert workshops in spite of
high opportunity cost of their time. The collection of secondary data was a very instructive ex‐
perience and I am grateful to a number of people for providing the required data sets for this
study. Out of these I want to mention Khun Phitsamai Satayaviboon, Khun Patcharin Nakapraw‐
ing, Khun Orasa Dissataporn of the DoAE and Khun Rajana Netsaengtip of the NSO.
For much of the fieldwork, I could rely on the support and dedication of Khun Lakchai and
Khun Patcharee Meenakanit and their staff from the Institute of Biological Agriculture and
Farmer Field Schools of the DoAE. Through many field visits and discussions they not only pro‐
vided opportunities to learn about Thai agriculture but also introduced me to many aspects of
Thai culture. Their help has been invaluable in organising and conducting the expert workshops.
I was lucky to have Khun Tattanakorn Moekchantuek as an experienced facilitator for conduct‐
ing the expert workshops.
My work in Thailand was supervised by Ajarn Dr. Suwanna Praneetvatakul and Ajarn Som‐
porn Isvilanonda at Kasetsart University, whose advice was instrumental and opened doors to
institutions and data sources, which otherwise would have remained closed. I am furthermore
indebted to my dear colleague Dr. Chuthaporn Vanit‐Anunchai for an excellent collaboration
during the fieldwork, her care and friendship. Together with the staff at the CAER made my stay
in Thailand a very pleasant one.
Finally, I would like to thank all my colleagues and especially the Thai expat community at the
Institute of Development and Agricultural Economics for the warm working atmosphere and my
family, who often had to stand back, for their understanding and support.
Funding of this research by the Deutsche Forschungsgemeinschaft is gratefully acknowledged.
