We consider a setting where a coalition of individuals chooses one or several alternatives from each set in a collection of choice sets. We examine the computational complexity of Pareto rationalizability. Pareto rationalizability requires that we can endow each individual in the coalition with...

This paper proposes a new formulation of the Borda rule in order to deal with the problem of cloning manipulation. This new Borda voting specification will be named: Dynamic Borda Voting (DBV) and it satisfies Arrow's IIA condition. The calculations, propositions with proof and explanations are...

Legislative misbehavior is best curbed through rational legislating requirements, whereby legislators must include in the legislative record an explicit elaboration of the path of lawmaking - from evidence, through findings, to ultimate conclusions - that clearly sets out the analytic connection...
