In October 2015, Princeton University Professor of Economics and International Affairs, Angus Deaton, was awarded the Nobel Prize in economics for his work charting global developments in health, wellbeing and inequality. The Legatum Institute was delighted to host Professor Deaton, in conversation with Democracy Lab editor, Christian Caryl, for a discussion on what it was like to receive 'that' phone call from Stockholm. They also discuss the debate around 'wealth versus health', and the rise of 'big data'.
