Taxes in a simple wealth distribution model by inelastically scattering particles

In this work we use an inelastic scattering process of particles to propose a model able to reproduce the salient features of the wealth distribution in an economy by including taxes to each trading process and redistributing that collected among the population according to a given criterion. Additionally, we show that different optimal levels of taxes may exist depending on the redistribution criterion.Comment: 7 pages, 7 figure

MODEL OF INFLUENCE: FROM INDIVIDUAL DECISIONS TO LOCKED-IN MARKETS

We introduce an agent-based, evolutionary model of decisions inspired by the increasing return theory. Agents have to choose between options taking into account their own preferences and externalities from their neighbors. The aim is to analyze the distribution of decisions in a square lattice domain and its dependence on the initial conditions. Numerical results show that an undesirable option may be adopted by the majority and may lock in markets by means of clever or lucky movements done at the beginning.Evolutionary game, increasing return, decision model
