– The purpose of this paper is to offer a systematic assessment of the magnitude of transaction costs of public infrastructure delivery, based on the three attributes of transaction costs, being the asset specificity, uncertainty and frequency of a transaction.
– Non-parametric tests were used to test the transaction cost differences between different procurement types.
– The authors find empirical support, based on a sample of 172 public infrastructure projects in Belgium, that construction firms make higher relation specific investments to their transaction partners under a public-private partnership (PPP) than a under a traditional public procurement (TPP). In addition, the authors found that PPP transactions are burdened by a greater uncertainty and a less mature market than TPP transactions.
– Given the complexity of this research, the scope is limited to: a strict distinction between two procurement types, one geographical area, a limited time scope and a focus on the private sector. Hence, the authors suggest that further research broadens the scope of either one of these aspects in order to get a better understanding of the total transaction cost burden of the public infrastructure market.
– This study offers policy makers form a better understanding of the transaction cost implications when evaluating different procurement types.
– This paper serves as one of the first systematic comparative analyses of the magnitude and determinants of transaction costs for the delivery of public infrastructure.
