The mean voter theorem suggests that all parties should rationally converge to the electoral center. Typically this leads to an outcome which is unattractive to the rich. This paper develops a general stochastic model of elections in which the electoral response is a¤ected by the valence (or...

Since Brazil's adoption of a universal health care policy in 1988, the country's health care has been delivered by a mix of private providers and free public providers. We examine whether income-based disparities in medical care usage still exist after the development of the public network using...

Since Brazil's adoption of universal health care in 1988, the country's health care system has consisted of a mix of private providers and free public providers. We test whether income-based disparities in medical visits and medications remain in Brazil despite universal coverage using a...

This essay shows that, for any non-collegial voting rule, σ, there exists an integer, s(σ), with this property: if the policy space, W, has dimension no greater than s(σ), then there exists a profile of smooth utilities on W, such that the core for σ at this profile is non-empty and...

This paper attempts to model elections by incorporating voter judgments about candidate and leader competence. The proposed model can be linked to Madison’s understanding of the nature of the choice of Chief Magistrate (Madison, James Madison: writings.

We develop a stochastic model of electoral competition in order to study the economic and political determinants of trade policy. We model a small open economy with two tradable goods, each of which is produced using a sector-specific factor (e.g., land and capital) and another factor that is...

Formal models of elections have emphasized the convergence of party leaders towards the centre of the electoral distribution. This paper attempts to resolve the apparent disparity between the formal result and the perception of political divergence by considering a model incorporating valence....

Social Choice traditionally employs the preferences of voters or agents as primitives. However, in most situations of constitutional decision-making the beliefs of the members of the electorate determine their secondary preferences or choices. Key choices in US political history, such as the...
