- 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.
