The paper derives a closed form solution for the maximal surplus generated by the pivotal mechanism in the case of a binary public good. The formula may be used to compare the pivotal mechanism to other mechanisms. An illustration is provided to demonstrate how such a comparison may be made.

Serizawa [3] characterized the set of strategy-proof, individually rational, no exploitative, and non-bossy social choice functions in economies with pure public goods. He left an open question whether non-bossiness is necessary for his characterization. We will prove that non-bossiness is...

This paper considers a model of society [script S] with a finite number of individuals, n, a finite set off alternatives, Omega, effective coalitions that must contain an a priori given number q of individuals. Its purpose is to extend the Nakamura Theorem (1979) to the quota games where...

Economists have used the term “nonbinary” to describe both choice functional nonbinariness (choice functions that cannot be rationalized as the maximizing outcome of a binary preference relation) and structural nonbinariness (the structure of the model dictates that pairs of alternatives do...
