UPF Economics and Business faculty members are at the forefront of these movements. In addition to work that integrates psychological and neuroscience dimensions into economic theory, the Department also has a well-equipped experimental laboratory (LeeX), where researchers can test existing and alternative theories of economics. Much of this work centres on issues in game theory and individual choice behaviour that lie at the heart of modern microeconomics.

The work in this area also has a strong applied element. For example, policies for public health typically make strong behavioural assumptions about individual behaviour that are consistent with conventional economic theory. However, what if people's judgments and preferences do not comply with these assumptions? How should ethical considerations be taken into account when dealing with economic decisions? Is it possible to change or "correct" behaviours, or do they tell us something about failures in the very concept of rationality itself?
