Extracting surpluses

I spent many years focused on infrastructure development, particularly working on getting private sector involvement into infrastructure investments, executing the projects, operating and maintaining them for government. The advantage, as we would often tout, has a lot to do with the efficiency of getting private sector with experience to do it. At the same time, it reduces need to use direct state budget for financing such projects, and reduce the need for government to get involved in the complexities of hiring specialists, working on those technical subjects that will not support other areas of government work.

We called these infrastructure projects public-private partnerships or PPPs. It has somehow unlocked lots of private sector financing into the market and supported infrastructure investments. That is all good but it made me wonder whether marketization infrastructure is necessarily a good thing. For one, collecting fees on a piece of infrastructure in order to maintain it sounds right; and that fee will somehow have to be regulated since the private sector party would try to extract all the surplus with its monopoly position. So what should the regulator allow? Average cost pricing or marginal cost pricing? There is a ‘right answer’ in economics but in practice it is always hard to really work out what is the long run marginal cost involved. Particularly if the amount of service you render in each time period varies with demand.

And who is to prevent the monopoly from trying to extract more surpluses by pushing the regulator to allow it to charge certain prices by gaming the criteria or the measurement methodologies that the public sector develops. So the cat and mouse game starts. Is this what we expect when we try to marketize infrastructure? And should we not expect it when we do go ahead to privatise infrastructure? Eventually the tax payers have to fund both the cat and the mouse – the regulator and the monopoly or the private shareholders’ profits. Does that really make sense in terms of overall economic efficiency?

And finally, can such a set up really deal with change? Especially with the energy and climate transition. A lot of infrastructure need to build in resilience, consider the climate impacts on not just their infrastructure but also their customers and the way their demand base will be evolving, whether that is going to impact existing business models. All that is not even accounting for the decarbonisation ambitions of their customers. Meanwhile, can these all become an excuse for extracting further surpluses?
