Abstract (Translated):
This paper aims to contribute to a theoretic and analytical basis to analyze Public Private Partnerships (PPPs) as a particular institutional arrangement from the point of view of its transaction costs, an approach that still has been neglected. That negligence has frequently jeopardized the implementation of PPPs in infrastructure projects. In order to achieve that end, it is discussed the application of the concept of hybrid institutional arrangements to PPPs in infrastructure sectors, making an effort to identify the sources of transaction costs intrinsic to that sort of PPPs.
