It is an enormous privilege for me to present the Deane–Stone lecture. As a young academic at the University of Southampton, I read so much of the work that came out of the National Institute of Economic and Social Research (NIESR) and was always impressed. Also, as an undergraduate and as a master’s student at the London School of Economics, Sir Richard Stone and Professor Phyllis Deane featured prominently on my reading list. In my opinion, they were pioneers of economic measurement and, today, economists benefit hugely from their legacy.
