Wealth distribution of wealth-scattered agents — •Hynek Lavička — Department of Physics, Faculty of Nuclear Sciences and Physical Engineering, Czech Technical University in Prague, Břehová 7, CZ-11519, Praha 1, Czech Republic

A model describing networked society of interacting particles-agents characterised by single internal variable - wealth, is investigated. Interaction between the agents is like inelastic scattering where overall wealth increases during the interaction. Every agent is associated to a node in the network of possible interactions. Two types of networks will be considered: small-world and scale-free networks. Simulations show the Pareto power-law tail in the wealth distribution. Moreover, correlations between wealth and connectivity and more detailed effects of the netwotk topology are found. Comparison with analytical results is provided.
