Decision models in public private partnerships: Conclusions, future research and policy recommendations

Public Private Partnerships (PPP) strategic investors and mode-specific business models are subsequently discussed within the transport PPP market, offering insight on the way these investors tend to standardise their business development based on their strengths and expertise. Strategic investors appear to be evolving their business development as their competence grows, and their transport mode-specific business models evolve over time. The assessment of project creditworthiness is investigated and new parameters are offered for consideration in an effort to add a degree of contextualisation to a process that is, by nature, largely standardised in order to serve its intended purpose. Ancor Suarez-Aleman, Athena Roumboutsos and Nunzia Carbonara suggest that project sponsor competence has been built on standardisation leading to market concentration. Contextualisation of creditworthiness cannot be achieved without transparency, as noted by Roumboutsos, Pantelias and Sfakianakis. Transparency is also required in project sponsor partnerships in order to achieve an effective complementarity of sponsor competences and, thereafter, effective and efficient value services
