Our team member Cars Hommes et al, have recently published an article in Science  in which they explore the role and relevance that complexity theory has (and should have) in economics. Extrapolating results from the natural sciences, estimating systemic risks on financial networks or deepening our understanding of emergent collective behavior of people might be crucial for our future development and stability. In their opinion:

The funding required for essential
policy-relevant and fundamental interdis-
ciplinary progress in these areas would be
trivial compared with the costs of systemic
financial failures or the collapse of the global
financial-economic system.

This article provides further evidence to the need of a project like IBSEN,  whose purpose is to  contribute to this way of doing social and economic sciences, by providing experimental resources and results in large-scale systems.
