Econo-posing

As krugman notes, the magic of the marketplace fails miserably in Health Care leading to higher costs and more inefficiency.

I would argue that you see a similar dynamic in the shadow banking system, especially with credit cards.

My econo-poseur analysis is that large corporation is general are not very efficient. The old aldage that a world class corporation is a C+ applies. So it's not surprising that you get inefficiencies and high-costs in network externality driven markets.
