Spatial implementation

Abstract

In a spatial model with Euclidean preferences, we introduce a new rule, the geometric median, and characterize it as the smallest rule (with respect to set inclusion) satisfying a collection of axioms. The geometric median is independent of the choice of coordinates and is Nash implementable.
