Over at the Free exchange blog there is an interesting piece on actions in the current crisis – namely whether to follow the “free market” route or the “inteventionist” route.
My hefty use of speech marks in the above sentence stems from the belief that there aren’t really two distinct schools of thought telling us what to do – there is a single framework of events that forms its descriptive and prescriptive powers from value judgments. These value judgments are thereby the true differences.
This quote sums it up for me:
The problem is that we’ve reached a point of market failure and uncertainty. It’s impossible to tell who the weak banks are.
The difference between the two prescriptions stems from how significant the implied market failure is – not a difference describing what the market failure is.
