Public-private partnerships: A multidimensional model for contracting

This paper considers the relationships between public and private organizations entering into public-private partnerships (PPPs) within the context of New Public Management (NPM). After offering a brief discussion of similarities and differences between public and private organizations and their relationships, it provides a short overview of how PPPs are organized in practice. Through elaborating on three dimensions of differentiation between public and private organizations -ownership, funding and control- it proposes a matrix model for identifying a suitable "dimensional mix" for PPP contracts.Public-private partnerships; hybrid organizations; contractual choices; qualitative comparative analysis;
