In a HARDtalk interview broadcast on Monday 9 February, Stephen Sackur talks to economist Ken Rogoff.
The world economy is in a mess. The pain is being felt from Wall Street banks to Chinese toy factories.
But is the prolonged downturn going to change fundamentally the global economic rules?
Ken Rogoff was the Chief Economist at the IMF from 2001 to 2003 and is a renowned student of economic history.
He talked to Stephen Sackur about the difference a new president can make.

Should US banks be nationalised?
One major decision President Obama has to make is whether it is necessary to nationalise major US banks, an idea which is alien to American culture.
Ken Rogoff thinks the president should 'move decisively' to nationalise the banks.

Is America embracing protectionism?
There are moves in the United States to encourage people to 'buy American'.
Does this mean that we are on the verge of a global trade war? Ken Rogoff says he hopes not but says 'I am nervous about it'.
If America turned protectionist it would 'turn a bad year or two into a bad five or six years' he says.
