Hybrid Galam-Bass Model for Technology Innovation

<p dir="ltr">This work proposes a hybrid model that combines the Galam model of opinion dynamics<br>with the Bass diffusion model used in technology adoption on Barabasi–Albert complex<br>networks. The main idea is to advance a version of the Bass model that can suitably<br>describe an opinion formation context while introducing irreversible transitions from<br>group B (opponents) to group A (supporters). Moreover, we extend the model to take into<br>account the presence of a charismatic competitor, which fosters conversion back to the<br>old technology. The approach is different from the introduction of a mean field due to the<br>interactions driven by the network structure. Additionally, we introduce the Kolmogorov–<br>Sinai entropy to quantify the system’s unpredictability and information loss over time. The<br>results show an increase in the regularity of the trajectories as the preferential attachment<br>parameter increases.</p>
