Abstract: Abstract We consider the problem of choosing a set of locations of a public good on the real line $${\mathbb {R}}$$ R when agents have single-peaked preferences over points. We ordinally extend preferences over compact subsets of $${\mathbb {R}}$$ R , and extend the results of Ching and Thomson (1996), Vohra (1999), and Klaus (2001) to choice correspondences. We show that efficiency and replacement-dominance characterize the class of target point functions (Corollary 2) while efficiency and population-monotonicity characterize the class of target set correspondences (Theorem 1).
