Diane Coyle is the Bennett Professor of Public Policy at the University of Cambridge. She co-directs the Bennett Institute where she heads research under the themes of progress and productivity. Diane’s new book (April 2025) is The Measure of Progress: Counting what really matters.

Her research focuses on productivity, the digital economy and digital policy, and economic measurement. She has been writing about the effects of digital technologies since her first book, The Weightless World, published in 1997. The underlying motivation for all her work is the question: what does it mean for the economy to improve, and who benefits?

Diane is also a member of the UK Government’s Industrial Strategy Council, New Towns Taskforce, and advises the Competition and Markets Authority. She has served previously in a number of public service roles including as Vice Chair of the BBC Trust, member of the Competition Commission, and of the Natural Capital Committee. Diane was awarded a DBE in 2023 for her contribution to economics and public policy.
