Modelling Socially Intelligent Agents - Bruce Edmonds

Example 1 - A Model of Emerging Markets

A three-sector model of emerging market economies has been developed by Scott Moss where the component firms learn how to behave in a newly emerging market economy (and in particular how to respond to the debt crisis). Firms communicate and trade with other firms and build rule-based models of their environment and the other firms. Thus they distinguish between the other firms around them and model them individually. The firms trade (and hence communicate with) only a set of locally accessible firms. Known qualitative behaviour characteristic of such economies (e.g. the characteristic inflation curve of Belarus) was only reproduced when the model was adapted so that firms would copy the observable behaviour of only the other firms they interacted with that they judged as successful. This was not the case when they had global access to information. Here the ability to distinguish, identify, and select other firms was critical to the overall behaviour. More about this model can be found in [18] and [14].

Of course, this model only starts to address the concerns I listed above about social intelligence, but it does show how the inclusion of the ability to individuate other agents and interact in a local and specific manner can critically effect the emergent properties of the whole system.
