<dcterms:abstract xml:lang="fr">Cette thèse étudie la co-évolution de l'apprentissage social et de la structure des réseaux, comblant le manque de compréhension sur leur impact mutuel sur les comportements.Le premier chapitre modélise comment l'apprentissage social améliore la performance pour les biens d'expérience, grâce aux recommandations et à la confiance. Le second explore l'impact des influenceurs et des systèmes de notation en ligne, montrant leurs limites (influenceurs négatifs, systèmes inefficaces avec goûts hétérogènes).Les chapitres 3 et 4 se concentrent sur les réseaux sociaux en ligne. Le chapitre 3 examine la polarisation, suggérant que les influenceurs pourraient l'atténuer et que les "bulles de filtre" pourraient être bénéfiques. Le chapitre 4 analyse comment les protocoles des plateformes façonnent les réseaux, déterminant la diffusion de l'information, l'action collective et l'efficacité comme marché du travail.</dcterms:abstract>
<dcterms:abstract xml:lang="en">This thesis explores the co-evolution of social learning and network structure, filling the gap in understanding their mutual impact on behavior.The first chapter models how social learning improves performance for experiential goods, driven by recommendations and trust. The second examines the impact of online influencers and rating systems, highlighting their limitations (negative influencer effects, system inefficiency with heterogeneous tastes).Chapters 3 and 4 focus on online social networks. Chapter 3 analyzes polarization, suggesting influencers might mitigate it and "filter bubbles" could be beneficial. Chapter 4 investigates how platform protocols shape networks, determining information diffusion, collective action, and job market efficiency.</dcterms:abstract>
