Network models of collective action commonly assume fixed social networks in which ties influence participation through social rewards. This implies that only certain ties are beneficial from the view of individual actors. Accordingly, in this study we allow that actors strategically revise their relations. Moreover, in our model actors also take into account possible network consequences in th...

This analysis extends theoretical models of ethnic boundary formation to account for the shifting and layered nature of ethnic boundaries. It focuses on the underlying structural conditions that facilitate the expansion of ethnic boundaries or the construction of a pan-national identity, and explores how organizing along an ethnic boundary affects collective efforts at the panethnic level. Two ...

Many models proposed to study the evolution of collective action rely on a formalism that represents social interactions as n-player games between individuals adopting discrete actions such as cooperate and defect. Despite the importance of spatial structure in biological collective action, the analysis of n-player games games in spatially structured populations has so far proved elusive. We ad...

Social computing platforms that advance collective action connect crowds and communities of participants, lower the cost of communication, facilitate deliberation, and help t...
