  In this paper we present a kinetic model with stochastic game-type
interactions, analyzing the relationship between the level of political
competition in a society and the degree of economic liberalization. The above
issue regards the complex interactions between economy and institutional
policies intended to introduce technological innovations in a society, where
technological innovations are intended in a broad sense comprehending reforms
critical to production. A special focus is placed on the political replacement
effect described in a macroscopic model by Acemoglu and Robinson (AR-model,
henceforth), which can determine the phenomenon of innovation 'blocking',
possibly leading to economic backwardness. One of the goals of our modelization
is to obtain a mesoscopic dynamical model whose macroscopic outputs are
qualitatively comparable with stylized facts of the AR-model. A set of
numerical solutions is presented showing the non monotonous relationship
between economic liberization and political competition, which can be
considered as an emergent phenomenon of the complex socio-economic interaction
dynamic.
