Good to see serious empirical work tearing down the tenets of neoliberal ideology. Too many things get accepted as self-evident truths.

I'm always curious about the profit in the private-public-partnership stories. The reduction in waste, even if it were real, does not just go back into the budget - a part of it must leak out as profits (a manifestation of the second law of thermodynamics in economy, maybe). So, taxes -> profits. Not a problem, I guess, if the contracts between gov and corporations are not too long-term, the competition is healthy, and the tenders are not rigged. Now, that's interesting - the government is assumed to be too corrupt and incompetent to manage these jobs itself, but when it comes to organizing an honest, competitive tender, it's doing that perfectly? :)

And, ultimately, a company on the market is driven to be efficient, that's easy to understand. But a company with a multi-year tender is not on the market.
