Credit crunch: bad maths


Paul Wilmott, an expert on quantitative finance - which is the application of mathematics to money-making - says some simple mathematical mistakes are in part to blame for the credit crunch.

He told BBC Radio 4's More or Less programme that these errors might have contributed to the mispricing of financial derivatives and thus to the travails of the banks, the credit crunch, and the economic downturn.

He explained to presenter Tim Harford how it could have happened.
