Abstract
This paper is part of Data-Pop Alliance’s ‘White Papers Series’. It originated in discussions between members of the ‘D4D team’ involved in the first Orange D4D challenge in the summer of 2013—including representatives of Orange France Telecom Group, World Economic Forum USA, Université Catholique de Louvain, MIT, UN Global Pulse, GSMA, and the authors of this paper. Its completion benefited from financial support from the World Bank Leadership, Learning and innovation group, which is gratefully acknowledged.
