The brave new world of virtual workers; also globalisation, the old and the new.

Globalisation: the history of the movement of goods, knowledge and people. Laurie Taylor talks to Richard Baldwin, Professor of International Economics at the Graduate Institute of International and Development Studies, Geneva and author of a groundbreaking new study. They were joined by Diane Coyle, Professor of Economics at the University of Manchester. Juliet Webster, Director of Work and Equality Research at the LSE, explores the brave new world of virtual workers - characterised by short contracts, flexible working hours and the blurring of boundaries between work and free time. Producer: Jayne Egerton.
