Resumen
The aim of this study was to understand some of the factors that influence the dynamics and efficiency of hybrid forms in the relationship between producers and buyers of the milk production chain in Paraná, state of Brazil. For this, we used the theoretical contribution of the Transaction Costs Economy and the Measurement Costs Economy. This study is qualitative, descriptive, and inductive, with a transversal cut. To achieve the objective, we used documentary, bibliographic and field research. The data were collected in the state of Paraná, through semi-structured interviews, and data analysis was conducted using the Content Analysis Method. The results showed the influence of the formal regulation (IN 62) and informal regulation (price) given by the institutional environment, and distinguished the categories of technification of the producers, as well as the efficiency of the hybrid governance in the level of technification. Hybrid forms were treated, being classified by category of technification of the producers and by type of contracting, in which different perspectives of efficiency in the transaction were identified. In the discussion chapter, it was possible to attribute efficiency to the formal contracts, associated to producers with high level of technification. The results also identified that this form of hiring guarantees the protection of legal property rights, minimizing the possibility of opportunistic behavior and maximizing the value of the transacted assets. In addition, we identified efficiency gaps in informal contracts, related to medium and low technology producers, mainly in the absence of guarantee of legal and economic rights. The non-inclusion of some dimensions of the asset and, therefore, its non-remuneration, allowed that conclusion.
