Burning Question

I like "By Invitation," an "expert" polls feature at The Economist. The question this time is:
Will the financial crisis and its aftermath lower the world economy's potential rate of growth?

Answers by contributing guests include:
[Yes] "previous potential growth rate...was, we now know, artificially inflated by counting the upside of risky investments made without properly accounting for their downside potential"
"No. History suggests the global economy will snap back to its pre-crisis trend"
"I will focus on the question of permanent v temporary effects..." blah blah blah.
