Abstract: Economy is demanding new models, able to understand and predict the evolutionof markets. To this respect, Econophysics is offering models of markets ascomplex systems, such as the gas-like model, able to predict moneydistributions observed in real economies. However, this model reveals sometechnical hitches to explain the power law Pareto distribution, observed inindividuals with high incomes. Here, non linear dynamics is introduced in thegas-like model. The results obtained demonstrate that a chaotic gas-like modelcan reproduce the two money distributions observed in real economiesExponential and Pareto. Moreover, it is able to control the transitionbetween them. This may give some insight of the micro-level causes thatoriginate unfair distributions of money in a global society. Ultimately, thechaotic model makes obvious the inherent instability of asymmetric scenarios,where sinks of wealth appear in the market and doom it to complete inequality.
