This paper describes a simulation study of decision-making. It is based on a model of social influence in small, task-oriented, groups. A process model of dyadic social influence is built on top of a dynamic model of status and task participation that describes the emergence of a stable power...

This paper investigates opinion dynamics and social influence in directed communication networks. We study the theoretical properties of a boundedly rational model of opinion formation in which individuals aggregate the information they receive from their neighbors by using weights that are a...

We investigate how the selection process of a leader affects team performance with respect to social learning. We use a lab experiment in which an incentivized guessing task is repeated in a star network with the leader at the center. Leader selection is either based on competence, on...

This paper investigates how information flows enable social networks to constitute social capital. By analyzingthe information content encoded in email communication in an executive recruiting firm, we examinethe long held but empirically untested assumption that diverse networks drive economic...

We study the fine-grained relationships among information flows, IT use,and individual information-worker productivity, by analyzing work at amidsize executive recruiting firm. We analyze both project-level andindividual-level performance using: (1) direct observation of over125,000 e-mail...
