Behavioural economics is a blend of traditional neoclassical microeconomics and empirically motivated assumptions whose goal is a better understanding of economic behaviour. It can be divided into behavioural decision theory and behavioural game theory. Each subfield differs from its mainstream counterpart by paying particular attention to the psychological realism of behavioural assumptions and their consistency with empirical evidence. The goal is to identify empirically important deviations from traditional assumptions, use the alternative assumptions the evidence suggests to build tractable formal models, and use the models to reconsider standard microeconomic questions.

The research group holds regular seminars in conjunction with the Centre for Experimental Social Sciences at Nuffield College. For further information: https://cess-nuffield.nuff.ox.ac.uk/.

The Nuffield Economic Theory seminars also periodically have speakers whose orientation is "behavioural".
