| Research Abstract |
We studied strategy-proof allocation rules in the international society where internationally held resource are allocated among counties. We studied allocation rules in two environment. One environment is such that the resource is perfectly divisible and countries have nonmonotonic preferences.
One environment is such that the resource is perfectly divisible and countries have nonmonotonic preferences. In this environment, we analyzed the uniform rule (Bennasy, 1982). We established that i)the uniform rule is a unique rule satisfying strategy-proofness, efficiency and symmetry on a minimally rich domain, and that ii)the maximal domain on which rules satisfying strategy-proofness, efficiency and symmetry is unique, and it is the signle-plateued domain.
The other environment is such that the resource is not divisible, but monetary compensation is possible. In this environment, we analyzed the Vickrey allocation rule. We established that the Viclrey allocation rule is a unique rule saysfying strategy-proofness, anonymity and individual rationality.
