Thank you.
Public-private partnerships are the product of experience that has been gained via traditional channels. Keep in mind that the private sector has always built public infrastructure. The public sector doesn't have the equipment required to build bridges, roads and other things of that nature. Standard practice is that the government first enters into a separate contract for the design phase of the project. Once it has the design in hand, the government then solicits bids to find a private firm to build the infrastructure. Once the infrastructure has been built, the government must see to its maintenance and operation.
Where is the problem? The person designing the infrastructure has absolutely no incentive to come up with the least costly solution possible. You get plans that are extremely difficult to build. The person building the infrastructure has absolutely no incentive to consider long-term maintenance. When cost overruns crop up during construction, the builder blames the design. And the designer's response? It's a construction problem. Governments are the ones on the hook in situations like that. The fact that the traditional approach routinely leads to cost overruns tells us that something is wrong with public projects.
One of the country's biggest problems is the upkeep of existing infrastructure, not the building of new infrastructure. Governments don't systematically consider the infrastructure's life cycle. What happens in the event of a cost overrun? It's always governments footing the bill. PPPs address that kind of issue.
How do you change the supply model to prevent such problems? You start by making sure that the same people are responsible for every phase of the project, and leave the job of achieving the most cost-effective outcomes up to them. Those people, then, are responsible for the project's design, construction and upkeep, making it impossible for them to pin the blame on someone else. That is a key feature of the PPP model, integration. Construction isn't the problem, it's everything that comes afterward. If the infrastructure doesn't work, the public's expectations aren't being met.
The only way we can make sure a project is done right is to rely on the discipline of capital markets to force private firms to build infrastructure that functions properly. As I say all the time, governments aren't all that adept at recovering their money when there's a problem; but they're very adept at not making any payments at the start of a project, only once it's been completed.
We're talking about loans and investments worth hundreds of millions of dollars. Given the size of those investments, the banks, or investors, can impose discipline on the private sector that governments can't.
