The Centre for Experimental Research on Fairness, Inequality and Rationality aims to conduct groundbreaking experimental research on how to address inequality in society. FAIR is comprised of three research groups, the Centre for Empirical Labor Economics (CELE), The Choice Lab (TCL), and Development (DEV).


Centre for Empirical Labor Economics aims to foster research on the multiple aspects of empirical labour economics. The research agenda includes several themed areas of focus: the labour market, education and health economics, in particular early investments and intergenerational mobility.


The Choice Lab uses economic experiments to study individual decision-making, particularly how people are motivated by moral, risk and institutional considerations. Areas of focus are global income inequality, tax policy, health care and management issues relevant to corporations and non-governmental organisations.


Development combines field experiments, smaller-scale controlled economic experiments, survey experiments and household surveys to better understand people's choices in low-income countries and provide research-based advice on how their lives can be improved. Our projects involve early childhood development, education, and entrepreneurship, with a focus on countries in East Africa.
