fair division; uniqueness of the uniform rule; envy- freeness; individual rationality
Summary: \textit{W. Thomson} [J. Econ. Theory 63, No. 2, 219-245 (1994; Zbl 0864.90008)] proved that the uniform rule of the fair division problem, where preferences are single-peaked, is the unique rule which is bilaterally consistent, continuous, Pareto optimal, and envy-free, in a setting of an infinite number of potential agents. We show that the uniqueness of the uniform rule is achieved without assuming continuity, even in a setting of a finite number of potential agents. A similar result is obtained by replacing envy- freeness with individual rationality from equal division.
