This research programme rigorously tests standard models of game theory and documents systematic empirical regularities that either support or reject these models. A primary goal is to develop formal extensions of the standard models so that they can be more predictive of actual behaviours in social interactions. We are particularly interested in social interactions where emotion and fairness concerns are important in shaping strategic behaviours.
This research programme conducts field interventions to induce positive behavioural change among people. A primary goal is to develop scalable field interventions that will lead to positive long-term outcomes for the society. We are particularly interested in areas where individuals fail to exert self-control (e.g. exercise, diet, and drug regimen) and where social norms are crucial in shaping behaviours.
