I think one good point that's been made is that in either case you're doing some sort of procurement for these large construction projects, so you're still sending out something to be bid. In many cases, you're still getting the same types of companies that might give some good examples of that.
At the very least, if there's a risk, the risk is still present in any type of procurement process. I think the potential mitigation the P3s may have is in the enforcement of the contracts. This may relate to the private finance issue. If it is financed privately and someone else is on the hook in case something goes wrong, it's much easier for the government to say they're just not paying them now. Sure, they're going to have to take over the project as it is now if they're committed to delivering the project, but they're not going to pay them. So they're not going to be able to pay back whoever gave them money in the first place. That is unique to something that is privately financed.
