The main research question is how individual choices are affected by moral considerations, in particular fairness considerations. The research group has looked at issues of fairness and responsibility, distributive justice, and perceptions of inequality. The Choice Lab is especially interested in the question why some inequalities are perceived as fair and others not.

The Choice Lab uses a wide set of experiments including randomized control trials, large-scale incentivized experiments with nationally representative populations, neuroeconomic experiments and survey experiments. The experiments are conducted, both in developed and developing countries.

The Choice Lab works closely together with experimental researchers and behavioural economic groups from all of over the world.
