The importance of fairness

Available for over a year

Ernst Fehr is well named: he’s an economist who writes about fairness. In fact, until his pioneering work, economists had been dismissive about whether fairness was a subject worthy of study. Now some have tipped Fehr to win a Nobel Prize. David Edmonds speaks to him about why it pays to be fair, and why people are less selfish than you think. Presented by David Edmonds Produced by Robbie Wojciechowski for the BBC World Service
