Trust and transaction costs in public–private partnerships — theoretical reflections and empirical findings

The paper makes an important contribution to the literature by reflecting on trust relations in PPPs, as well as providing empirical evidence for higher transaction costs in PPPs, compared to entirely public sector provision
