Balloons explode, don’t they?

It is amazing that so soon after having witnessed what disasters comes from having empowered credit agencies to put up their AAA signs showing the roads to no risk-lands Arvind Subramanian and John Williamson dare to recommend setting up zones for asset prices. “Dear I don’t think we should buy our house here because it has a 343 bubble rating. Perhaps I should look for a job in Toledo?”, “Put the puritans in charge of the punchbowl”, February 12.

There is nothing wrong for a central banker to keep an eye on assets prices such as houses to decide on monetary policies but if he wants to make any official use of it he should first make sure he does not own a house so as to be free of any conflict of interest but, more importantly, he needs to remember that bubbles, even though they might hurt when they explode, have a role to play in taking human and economic development forward.

A world without bubbles gets to be closer to a world without illusions.
