This episode explores new insights into the productivity puzzle from two fresh pieces of work. First, Diane Coyle discusses her book The Measure of Progress, explaining why what we measure is profoundly important but increasingly difficult. Then, Jan Mischke from the McKinsey Global Institute shares a striking finding from their report The Power of One: a relatively small number of "standout firms" deliver a very big share of a country's productivity growth.

Host Professor Bart van Ark is joined by:

• Diane Coyle, Bennett Professor of Public Policy and Co-Director of the Bennett Institute for Public Policy.
• Jan Mischke, Partner at McKinsey Global Institute.
