Cutting the financial sector down to size [it's in the air]

Over at Crooked Timber John Quiggin posts:

That’s the provisional title I used for my latest piece in Inside Story. Peter Browne, the editor, gave it the longer and clearer title “Want to reduce the power of the finance sector? Start by looking at climate change”.

The central idea is a comparison between the process of decarbonizing the world economy and that of definancialising it, by reducing the power and influence of the financial sector. Both seemed almost impossible only a decade ago, but the first is now well under way.

There’s also an analogy between the favored economists’ approach in both cases: reliance on price based measures such as carbon taxes and Tobin taxes. Despite the theoretical appeal of such measures, it looks as if regulation will end up doing much of the heavy work.

Note yesterday's post about Farhad Manjoo making pretty much the same call.
