Abstract: In recent years there has been a great interest in the phenomenon of economic inequality, especially in relation to its connection with other important aspects of an advanced economy, for example attitude towards risk, growth, financial developments, and so on. In this talk, based on a joint work with Eugenio Regazzini, I will introduce a model for the surplus/deficit distribution, which points out a relationship between agents' risk aversion and inequality. More precisely, on the one hand, the long-time surplus/deficit distribution turns out to be a weak Pareto law whose exponent is given by an affine transformation of the agents relative risk aversion index, supposed to be the same for every agent. On the other hand, it is proved that concentration in a weak Pareto law can be measured through a function of its exponent. This way, a link is established between inequality and risk aversion. Finally, some feasible actions of economic policies suitable for the control of inequality are derived.
