Idea 2: PPPs have worked well in seaports and airports; less so in roads and rail

![Page 7: Addressing risk and uncertainty in long-term PPP contracts · •Yes (endogenous risks) − Make good outcomes more likely, and bad oucomes less likely − De-risking: invest/spend](https://reader034.fdocuments.in/reader034/viewer/2022051917/6009863102f82005fc2e61b1/html5/thumbnails/7.jpg)
PPP performance in transport infrastructure
• Seaports and airports (≈ 20 percent of total transport infra spending)
– Drewry database: 252 landlord container ports (2014)
– PPIAFF database: 141 private/concessioned airports (2014)
– Private investment accomodated massive increases in capacity & trade
• Rail, roads, tunnels and bridges (≈ 80 percent of total transport infra spending)
– Small participation in general, and concentrated in a few countries
– Contracts are often renegotiated

Idea 3: risk and insufficient funding are different problems

![Page 9: Addressing risk and uncertainty in long-term PPP contracts · •Yes (endogenous risks) − Make good outcomes more likely, and bad oucomes less likely − De-risking: invest/spend](https://reader034.fdocuments.in/reader034/viewer/2022051917/6009863102f82005fc2e61b1/html5/thumbnails/9.jpg)
–Funding: who will pay for the project
(users/tolls; taxpayers/budget; a combination
→ see Vasallo)
–Risk: unpredictable variation in total project
value (Revenues ─ Costs): you don’t know
which outcome will realize

Idea 4: the key question about a risk is: can some party do something about it?
10
![Page 11: Addressing risk and uncertainty in long-term PPP contracts · •Yes (endogenous risks) − Make good outcomes more likely, and bad oucomes less likely − De-risking: invest/spend](https://reader034.fdocuments.in/reader034/viewer/2022051917/6009863102f82005fc2e61b1/html5/thumbnails/11.jpg)
The answers
• Yes (endogenous risks)
− Make good outcomes more likely, and bad oucomes less likely
− De-risking: invest/spend to clarify what the risk is about or reduce the magnitude of the unpredictable variation
− The questions: (i) who should be responsible for the risk; (ii) what do you get in exchange for the risk transfer
• No (exogenous risks):
– Who is best suited to bear/spread the risk?
– The party that bears exogenous risk “sells” insurance
– The question: who should sell insurance to whom?

Idea 5: thoughtful risk allocation is a de-risking strategy by itself
12
![Page 13: Addressing risk and uncertainty in long-term PPP contracts · •Yes (endogenous risks) − Make good outcomes more likely, and bad oucomes less likely − De-risking: invest/spend](https://reader034.fdocuments.in/reader034/viewer/2022051917/6009863102f82005fc2e61b1/html5/thumbnails/13.jpg)
An example: demand risk in ports and roads
• Seaports: quality & speed of service can affect
demand for the port dramatically → substantial
part of demand risk is endogenous → let the PPP
bear demand risk
• Roads: largely exogenous once road is available
→ should the government “buy” or “sell”
insurance?

Roads and demand risk
• Hard to think that PPP investors are in the insurance
business (SPV + capital market?)
• Government can spread risk among taxpayers
• Private infrastructure (terminals, pipelines) use take-
or-pay contracts
• Lot’s of renegotiations because demand was too low

Idea 6: the government has more and better options if the road PPP doesn’t bear demand risk
18
![Page 19: Addressing risk and uncertainty in long-term PPP contracts · •Yes (endogenous risks) − Make good outcomes more likely, and bad oucomes less likely − De-risking: invest/spend](https://reader034.fdocuments.in/reader034/viewer/2022051917/6009863102f82005fc2e61b1/html5/thumbnails/19.jpg)
• PPP revenues and bids are tied to investment, not user demand, and fixed at the beginning of the concession
• A buyout call option is easier to value (Total − Extant Revenues); the government can retain flexibility without expropriating
–Option to revamp the infrastructure
–Option to bear obsolescence risk
• Separation of tolling and funding of PPPs: a road fund which pools availability-based contracts (Vasallo’s proposal)
