How do political parties decide how to allocate campaign resources between vote-buying and traditional campaigning? This decision ultimately determines the presence and extent of vote-buying. Nevertheless, we lack a proper understanding of how this decision is made. This paper aims to fill this gap by building a political competition model with two political parties, brokers, and expressive and non-expressive citizens who value political ideology and public goods.

A key topic in social science is explaining why states are organized in very different ways with important consequences for economic prosperity. In this research we use the history of Colombian paramilitarism to advance a new hypothesis about it: the organization of the state fundamentally reflects the kinship structure of society. We lay out a model in which more central commanders within the networks of paramilitary groups elicit greater effort from their combatants, an effect that is complementary to recruiting more kin members (i.e., family) .
