This paper analyzes strategy-proof collective choice rules when individuals have single-crossing preferences on a finite and ordered set of social alternatives. It shows that a social choice rule is anonymous, unanimous, and strategy-proof on a maximal single-crossing domain if and only if it is...

This paper studies the strategic foundations of the Representative Voter Theorem (Rothstein, 1991), also called the second version of the Median Voter Theorem. As a by-product, it also considers the existence of non-trivial strategy-proof social choice functions over the domain of...

We study the effect of power sharing over income redistribution among different socio-economic groups in a model of redistributive politics with fairness concern. We prove that a unique pure-strategy equilibrium exists under fairly general conditions; and we show that equilibrium transfers...
