Can the study of the physics of flocking be used to model collective economic behavior? Describing a project to describe the flight of tens of thousands of starlings, Roland Piquepaille quotes one effort in biological physics with just that goal:
The Department of Biological Physics, at Eötvös University in Budapest, Hungary, has clearly defined the goals of the project. Here is the last one. 'As far as collective movements are common phenomena also in human behaviour (particular relevant in economics) we would like to explore the possibility of exporting the models and the techniques to economic collective choices. In this way we try to develop ways to investigate the reasons of social events, e.g. fashions, to understand socio-economic herding, and possibly to devise methods to tame dangerous excessive market fluctuations.'
Like the Dirk Brockmann's work studying money circulation in order to track how influenza travels, these bio-physical efforts just interest me.
