Contributor(s): Professor Sir Paul Collier, Professor Dani Rodrik | 2015 marks the centenary of the birth of the LSE’s Nobel Prize winning economist, William Arthur Lewis (1915-1991). Sir Arthur Lewis was awarded the Nobel Prize for economics for “pioneering research into economic development research with particular consideration of the problems of developing countries”. As part of LSE's marking of the centenary, this event will see Rodrik and Collier reflect on some important themes on the subject of “Understanding Economic Development” and their relation to Lewis’s earlier work.
