Strategy-proof social choice functions are characterized for societies
where the space of alternatives is any full dimensional compact subse
t of a Euclidean space and all voters have generalized single-peaked p
references. Our results build upon and extend those obtained for carte
sian product ranges by Border and Jordan (1983). By admitting a large
set of non-Cartesian ranges, we give a partial answer to the major ope
n question left unresolved in this pioneering article. We prove that o
ur class is composed by generalized median voter schemes which satisfy
an additional condition, called the intersection property [Barbera, M
asso, and Neme (1997)]. Journal Of Economic Literature Classification
