Global and local processes in a model of innovation

In this work we present the introduction of spatial constraintsin a model of generation and diffusion of innovations. The presenceof spatial limitations introduces several feedbacks, whose main effectsare the decrease of global diversity in favour of a higher robustness,despite the apparent minor success of the individual agents. All thesefeatures hold contemporarily, but the individuated feedbacks are able toexplain their only apparently contradictory nature. None of these resultsis obvious, nor can it be simply deduced from the qualitative theory.Moreover, the simulations could make possible comparisons between themodel behaviours and the theory claims, indicating new ways of improvementand development
