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.
