In this paper I study the strategic implications of coalition formation in an assembly. A coalition forms a voting bloc to coordinate the voting behavior of its members, acting as a single player and affecting the policy outcome. In a game of endogenous coalition formation, I show that voting...

Members of an assembly that chooses policies on a series of multidimensional ideological issues have incentives to coalesce and coordinate their votes, forming political parties. If an agent has an advantage to organize a party at a lower cost, a unique party forms and the policy outcome moves...

I provide an axiomatic foundation for the assumption of specific utility functions in a multidimensional spatial model, endogenizing the spatial representation of the set of alternatives. Given a set of objects with multiple attributes, I find simple necessary and sufficient conditions on...

Given a set of alternatives with multiple attributes, I characterize the set of preference profiles that are representable by weighted versions of a class of utility functions indexed by a parameter δ 0, where δ ≥ 1 corresponds to the set of Minkowski’s metric functions. In light of the...

This work follows the citizen candidate model of Besley and Coate (1997) to show that for a unidimensional policy issue, a moderate default policy rules out equilibrium outcomes in which there is an uncontested candidate

This paper studies the advantages that a coalition of agents obtains by forming a voting bloc to pool their votes and cast them all together. We identify the necessary and sufficient conditions for an agent to benefit from the formation of the voting bloc, both if the agent is a member of the...
