Hotpants v the knockout mouse

A brand new Radio 4 series in which Tim Harford tells an audience short stories about fascinating people and ideas in economics.

The presenter of Radio 4's "More or Less" weaves together economic ideas with remarkable personal histories in some unusual locations.

In a shop window on London's Regent Street Tim turns his attention to heated pants - oh yes! - and the business of innovation. We hear the moving story of Mario Capecchi, whose struggle to get funding for his experiments tells us much about where new ideas come from - and how to foster them.

Producer: Adele Armstrong.
