In this study we sought to investigate the governance structure between farmers and processing company potato agri-food systems Central-Eastern Paraná. Using as a base the New Institutional Economics and using the assumptions and transaction attributes present in Transaction Cost Economics developed by Williamson (1981). We conducted a qualitative study of descriptive character in a Cooperative located in Central-Eastern Paraná and cooperatives that make up the group of potato producer unit. Through interviews, observations and document analysis it was found that the transactions in relation to its attributes, highfrequency, low uncertainty and high specificity of human assets, and in relation to behavioral assumptions can identify the lower bounded rationality and especially the absence of opportunism among agents. Unlike stated by Williamson (1985) found the governance structure of the contract and is not a promise, and the contract plays a major role as a mechanism of organizing information and transparency, than the expected to the assumptions of the theory.
