Lo studio della diffusione delle innovazioni descrive come nuove idee, prodotti o pratiche si diffondono all’interno di una popolazione. Questa tematica è una delle più dibattute, nel corso degli anni, nell’ambito delle scienze comportamentali, quali l’antropologia, la sociologia e le scienze gestionali. Vari modelli sono stati proposti in letteratura, ma i due capisaldi sono quelli proposti da F. Bass e E. Rogers. Il presente elaborato si pone come obiettivo quello di analizzare i due modelli citati, esponendo gli aspetti chiave ed evidenziando i principali limiti. Successivamente viene analizzato un modello probabilistico, proposto in letteratura, basato su una popolazione di agenti eterogenei e connessi tra loro. Il modello presentato è in grado di rappresentare la dinamica della diffusione delle innovazioni nel tempo, articolandola in due stadi: conoscenza e adozione.

Abstract
The study of the diffusion of innovations describes how new ideas, products, or practices spread in a population. This topic has been one of the most discussed over the years in the field of behavioral sciences, such as anthropology, sociology, and management sciences. Various models have been proposed in literature, but the two milestones are those proposed by F. Bass and E. Rogers. This paper aims to analyze these two models, delineating their key aspects and highlighting their main limitations. Subsequently, a probabilistic model proposed in literature, based on a population of heterogeneous and interconnected agents, is examined. The model is able to represent the dynamics of a two-stage mechanism that describes the diffusion of innovation over time, categorizing it into two stages: awareness and adoption.File | Dimensione | Formato | |
