Ben D’Exelle is a Professor of Development Economics at the University of East Anglia. His research focuses on understanding individual behaviour and decision-making, particularly how these are shaped by social interactions within households and communities. He applies this perspective across a wide range of areas, including health, economic development, labour, gender, the environment, and agriculture. Most of his work is conducted in low- and middle-income countries, motivated by the goal of informing more effective policies to address pressing development challenges. His research methodology places strong emphasis on experimental approaches, including randomised controlled trials as well as laboratory experiments conducted in computer labs and in field settings. He has led and contributed to projects in Uganda, Tanzania, Burkina Faso, Nicaragua, Colombia, Peru, Bangladesh, Côte d’Ivoire, the Dominican Republic, and Zanzibar.
