Crossing Channels

Our experts discuss the tradeoff between experience, expertise, skill and judgement as society’s leaders age.

This episode is hosted by Rory Cellan-Jones (former technology correspondent for the BBC), and features guest experts Professor Dame Diane Coyle (Bennett Institute for Public Policy), Professor Ruth Mace (UCL/IAST) and Professor Paul Seabright (IAST).
