This award funds research in economic theory. The project seeks to improve our understanding of how social networks shape the spread of opinions, products, and ideas. The core objective is to turn insights from theoretical models into practical guidance on how to conduct targeted seeding, how to design regulations for social media, and how to advertise new products with uncertain quality. The award funds three projects. The first project will develop a framework to study how best to target individuals based on their network positions in order to spread a new idea or innovation.
