Does collective identity drive protest participation? A long line of research argues that can explain why protesters do not free ride and how specific movement strategies are chosen. Quantitative studies, however, inconsistent in defining operationalizing identity, making it difficult to understand under what conditions extent explains participation. In this paper, we clearly differentiate betw...

. In this paper we address the problem of collective norms, and discuss two action logics for that purpose. The first action logic is based on the action modality Ei, where expressions of the form Eip are read as ‘agent brings about (sees to it) that ’. This operator relates an agent with the effects of his action, and abstracts away details of the specific actions. We will show that this abstr...

We study how norms can solve distributional conflict inside a clan and the efficient coordination of collective action in a conflict with an external enemy. We characterize a fully non-cooperative equilibrium in a finite game in which a self-enforcing norm coordinates the members on efficient collective action and on a peaceful distribution of the returns of collective action.
