This week's Analysis presenter Stephanie Flanders
BBC Radio 4's Analysis: The Economist's New Clothes is broadcast on Monday 2 November at 20.30 BST.
As an economist herself, Stephanie Flanders is well placed to ask some of the profession's most eminent participants - how could they get it so wrong?
Was it overly sophisticated models that only those with knowledge of higher mathematics could figure out? Or, could it have been the notion that risk had been permanently tamed that lulled many in the financial world into a false sense of security?
Part of the debate being conducted in the hallways of higher learning has to do with arguments between those who believe in the theories of John Maynard Keynes and those who would rather place their faith in the theories of efficient markets.
Surprisingly, this isn't a new argument at all as Lord Robert Skidelsky, author of Keynes, The Return of the Master points out:
"I think Keynes would have said that the present state of economics is pretty bad. They're arguing about exactly the same things they were arguing about before, between the view that the market is self-correcting and between the view that it isn't. "
Perhaps it's how we measure human behaviours that needs to be changed. That's the thesis of one growing school of thought called behavioural economics. One of its most prominent proponents is Richard Thaler of the University of Chicago and co-author of the book Nudge.
"The models kept assuming people were smarter and smarter, but the world was getting harder and harder and so the models were getting further away from reality....when you have Citibank selling liquidity puts and the Vice Chairman of Citibank admitting later that he had never heard the term 'liquidity put', then you know you're dealing in a completely new world."
However, if the profession is going to go forward - economists have to be realistic about what they can know and what they can teach the world. That is an idea expressed by Bank of England Deputy Governor, Charles Bean:
"Even though economists' understanding will often turn out to be misplaced, that doesn't mean to say that we're worse off using economic thinking than using gut reaction and all sorts of completely uninformed thinking."
The economics profession has taken quite a knock since the recession and it will take some time before the warring factions on either side of the debate come to any agreeable conclusions. But, while it may be a tough time to be an economist, it's an incredibly interesting time to study economics.
