Econo-Girl was discussing the issue of flu vaccines related to a previous post. The 'shortage' of flu vaccines is another example of the failures of a purely market-driven system of resource distribution. There was not economic incentive to produce enough vaccine for everyone. So enough was not created. That's what you call efficient?
Econo-Girl said it once, and will say it again:
Sometimes the Invisible Hand of the marketplace needs a slap from a ruler.
