This paper analyses a simultaneous game of network formation and information acquisition where the benefit structure is … such that the benefit that an agent derives from the network she is located in depends on the maximum information that … someone in her neighbourhood, including herself, acquires. It turns out that in equilibrium star network emerges as the unique …

We introduce a model of strategic experimentation on social networks where forwardlooking agents learn from their own … own experimentation, so total information decreases with network density; we determine density thresholds below which … agents asymptotically learn the state. In contrast, agent welfare is single-peaked in network density, and achieves a second …

The paper analyzes a dynamic model of rational strategic learning in a network. It complements existing literature by … network. We show that the delay in information transmission caused by incomplete network structures may induce players to … increase own experimentation efforts. As a consequence a complete network can fail to be optimal even if there are no costs for …

We combine network formation and information transmission in a simple model and predict that people reveal less …

Networks and the embedded relationships are critical determinants of how people communicate and form beliefs. The … studies observational learning in networks of friends versus strangers. A consumer decides whether to adopt a product after … heterogeneity in the stranger-network than in the friend-network. We show that when the network size is small, observing friends …

This paper presents a non-Bayesian model of social learning in networks in an environment with a finite set of actions … observing the previous choices of the network members to whom they are connected. We identify three properties of individual … such properties and establish that consensus occurs in arbitrary strongly connected networks if and only if the revision …

Theoretical models on network formation focus mostly on the stability and efficiency of equilibria, but they cannot … deliver an understanding of why specific equilibrium networks are selected or whether they are all actually reachable from any … starting network. To study factors affecting equilibrium selection, we designed a network formation experiment with multiple …
