Abstract

The aim of the paper is threefold. First of all, since our main goal is to apply the discrete thermostatted kinetic framework to a socio-economic system whose space of microscopic states is discrete, we discuss the inverse problem (see the Introduction) in the discrete case. Next, we propose an example of a socio-economic system of the above kind, paying special attention to the choice of a particularly meaningful and plausible initial probability distribution on the state space. Finally, we sketch a first simple numerical simulation of the evolution of the system, just in order to show that the appropriate choice of initial conditions leads to a forecast of such evolution which seems to fit the experienced evolutions of western societies at present.
