This paper attempts to extend existing models of political agency to an environment in which voting may be divided between informed and instrumental, informed and ‘expressive’ (Brennan and Lomasky (1993)) and uninformed due to ‘rational irrationality’ (Caplan (2007)). It constructs a...

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...

Brennan and Hamlin (1998) predict that moderates are more likely to be expressive rather than instrumental voters, but do not test this hypothesis. Greene and Nelson (2002) claim to reject this, by finding that extremists are as likely to vote as moderates. We argue that Greene and Nelson's...

We construct models of the endogenous formation of political groups designed to capture some of the key features of political and social conflict. We draw on the `citizen candidate' approach and consider both instrumental and expressive approaches to understanding group formation and conflict...

This article analyses negative externalities that policy makers in one region or group may impose upon the citizens of neighbouring regions or groups. These externalities may be material, but they may also be psychological (in the form of envy). The latter form of externality may arise from the...

This paper reviews four economic theories of leadership selection in conflict settings. The 'credibility rationale', argues that hawks may actually be necessary to initiate peace agreements. The 'bargaining rationale' predicts that while doves are more likely to secure peace, post-conflict hawks...

The approaches and opinions of economists often dominate public policy discussion. Economists have gained this privileged position partly (or perhaps mainly) because of the obvious relevance of their subject matter, but also because of the unified methodology (neo-classical economics) that the...
