The kinetic gas theory, like the two-agent money exchange model, recently introduced in the econophysics of wealth distributions, is revisited. The emergence of a Boltzmann–Gibbs-like distribution of money into Pareto's law in the tail of the distribution is examined in terms of a 2×2...

We examine the concept of relaxation in the wealth exchange models that are recently proposed in econophysics to interpret wealth distributions. To quantify and characterize the process of relaxation, we define an appropriate quantity and evaluate that numerically for the systems of many agents....
