Leadership and conflict

We model the choice of leaders of groups within society, where leaders influence both the mode of interaction between groups (either peaceful compromise or costly conflict) and the outcome of these interactions. Group members may choose leaders strategically/instrumentally or they may choose leaders expressively. We characterize the equilibria of the instrumental choice model and also argue that leadership elections may overemphasise the role of expressive considerations in the choice of leader, and that this may result in increased conflict between groups
