Recent research on social contagion has demonstrated significant effects of network topology on the dynamics of diffusion. However, network topologies are not given a priori. Rather, they are patterns of relations that emerge from individual and structural features of society, such as population composition, group heterogeneity, homophily, and social consolidation. Following Blau and Schwartz, ...

Norms emerge as repeated interactions between individuals give rise to biases toward actions or behaviors which spread through the society until one behavior is adapted as the default behavior, even when multiple acceptable behaviors exist. Of particular interest to us is how and whe...

Here, we formalize the process by which collaborating individuals (1) reason about group plans during interaction, and (2) use task features to abstractly represent norms. In Experiment 1, we test the assumptions of our model in a gridworld that requires coordination and contr...

The optimal behavior of each intermediary regarding its attitude toward risk, the quality of the projects that it undertakes, and the intermediaries it chooses to interact with, is affected by the behavior of its counterparties. These strategic network e...
