Public Private Partnerships for Transport Infrastructure: Renegotiation and Economic Outcomes
Roundtable Report, Policy Insights,
23 February 2017
- Use renegotiation of PPPs only in exceptional cases.
- Use an independent jury to assess whether the outcome of a PPP is what parties might have been expected to negotiate had they foreseen a change that has occurred.
- Consider to task an independent body with determining when renegotiation of a PPP is legitimate.
- Include reputation and demonstrated competence in selection criteria for a PPP.
- Compare advantages and weaknesses of PPPs versus other forms of private capital.
Quantifying the Socio-economic Benefits of Transport
Roundtable Report, Policy Insights,
20 January 2017
- Cost-benefit analysis (CBA) guidelines can be expanded to include reliability and some wider impacts.
- Further research into reliability benefits is needed to improve confidence in results.
- Wider economic impacts should be examined in cases where they are expected to be significant.
- Further research into the impacts and tools for capturing wider impacts is needed.
- Cost-benefit analysis (CBA) can play an important role in decision making, but need not dominate.

- Make better use of demand forecasts in airport infrastructure planning.
Better Regulation of Public-Private Partnerships for Transport Infrastructure
Roundtable Report, Policy Insights,
24 September 2013
- A mix of financing models spreads risks.
- A dedicated budget for PPPs, set in relation to the rate at which future liabilities will be accumulated, can provide such a limit.
- Explicit consideration of alternative financing arrangements should be employed in determining whether to proceed with PPP projects.
- It is recommended that governments require PPP projects to pass tests of affordability and to clear the hurdle rates of return generally applied to publicly financed transport projects.
- The expected cost of PPP projects should take account of cost inflation resulting from the propensity for projects to be renegotiated.
- At the individual project level, risks should be assigned to the party best able to manage them, along with rights to make related decisions.
- Assigning demand risk is not straightforward and risk sharing arrangements are therefore common.
- Continuity of resources and expertise is essential for addressing strategic behaviour and optimism bias more generally.
- Regulatory agencies are well placed to ensure transparency and accountability by publishing reports on the criteria employed to make decisions and publishing contracts.
