Anatomy of public-private partnerships: Creation, financing, and renegotiations

This paper presents the main reasons why public-private partnerships (PPPs) are adopted as well as the possible disadvantages for the public and private sectors.

Furthermore, the two case studies illustrate how the renegotiation processes are conducted when the public-private contracts have to be altered and what determines (un)successful renegotiations
