My research revolves around the themes of cooperation, trust, and (the dynamics of) social networks, with applications to adolescent networks, online social networks, and laboratory experiments.
Current research projects/themes:
Cooperation and trust in dynamic networksMuch sociological research suggests that certain types of network structures, in particular structures with much closure, promote cooperation in social dilemmas. If that is the case, then how can we explain the emergence of these network structures? Under what conditions are actors willing to invest in social cohesion? We address such questions using formal theoretical models, simulations, and laboratory experiments. Collaborators: Vincent Buskens, Vincenz Frey, Stephanie Rosenkranz, Werner Raub, Karen S. Cook, Roeliene van Es.
Learning in social networksOne of the best known aspects of social networks is their capacity to transmit information, which in turn leads to differential access to valuable information by actors with different network positions (i.e., "the strength of weak ties" or "structural holes"). Yet, studies in which a causal connection between network structure and learning is empirically established are relatively rare. In a number of experiments, we study how actors use information obtained via a social network to solve problems and how they invest in such networks. Collaborators: Vincent Buskens, Bas Hofstra, Charlotte Rutten.Structure and dynamics of online social networksThe emergence of online social media platforms allows for the study of social network structure at a very large scale, for the first time in the history of sociology. In a number of larger and smaller projects with various collaborators, I study the large-scale structure of online social networks, how they relate to “offline” social networks, and their impact on social processes. Collaborators: Frank van Tubergen, Bas Hofstra, Remko Helms, Marco Spruit, Erik van Ingen, Lukas Norbutas.
Trust and the sharing economyThe recently evolved “sharing economy”, propelled by online interaction platforms and social media, challenges established forms of economic exchange and makes big promises with regard to sustainability, efficiency, equality, and democratization. Yet, the mechanisms by which the sharing economy functions, in particular the essential emergence of trust in sharing economy interactions, are poorly understood. We address such issues using online experiments and online data. Collaborators (among others): Paolo Parigi, Lukas Norbutas.
