Jan-Emmanuel De Neve is an economist specializing in behavioural economics, public policy, and human wellbeing. He earned his PhD at the London School of Economics and was a Fulbright Scholar at Harvard University. After teaching and conducting research at University College London and INSEAD, he joined the University of Oxford, where he directs the Wellbeing Research Centre. His empirical work examines how happiness relates to income and economic growth, and how employees’ wellbeing is associated with productivity and firm performance. He joined the World Happiness Report as an associate editor in 2017 and became a co-editor in 2020. He also co-founded the World Wellbeing Movement, which works to place wellbeing measures within business and public policy. With Richard Layard, he published Wellbeing: Science and Policy in 2023; its Japanese edition, Werubiingu-gaku: Riron, Ebidensu, Jissen, followed in 2025. The textbook brings together methods for measuring and explaining wellbeing with evidence on family life, education, health, unemployment, income, and communities. It also considers how governments can compare policies by their cost-effectiveness in improving wellbeing. In Why Workplace Wellbeing Matters (2025), co-written with George Ward, he turned to the relationship between working life and organisational performance. Drawing on large-scale datasets, including more than 20 million responses collected through a partnership with Indeed, the authors examined differences in wellbeing across occupations, companies, industries, and countries. They investigated its connections with productivity, recruitment, retention, and financial and stock-market performance, and assessed evidence on interventions to improve employees’ experience of work.
