Separable Preferences, Strategyproofness, and Decomposability

The authors consider strategyproof social choice functions defined over product domains. If preferences are strict orderings and separable, then strategyproof social choice functions must be decomposable provided that the domain of preferences is rich. The authors provide several applications of this result, including a characterization of the libertarian social choice function.
