This result is in consonance with Tatlidil and Aktur (2004) who revealed that the transaction cost (proxied by transportation cost) of tomato contract farmers ($25.90) was lower than the non-contract farmers ($47.20) in the Bida district of Canakhale province, Turkey.	cache/ajoaa-1530.pdf	txt/ajoaa-1530.txt
