Strategy-proofness and Equal-cost Sharing for a Binary Excludable Public Good with Fixed Cost. Working Paper, University of Padua.

Abstract:

For the provision of a binary public good we characterize the set of all strategyproof social choice functions and how that, if the binary public good is excludable and has a fixed cost, the equal-cost sharing rule minimizes the maximal welfare loss among the class of all strategy-proof, individually rational, and budget balanced rules.
