抄録	We consider the problem of choosing a level of a public good on an intervalof the real line among a group of agents. A probabilistic rule chooses aprobability distribution over the interval for each preference profile. We investigatestrategy-proof probabilistic rules in the case where distributions arecompared based on stochastic dominance relations. First, on a “minimallyrich domain", we characterize the so-called probabilistic generalized medianrules (Ehlers et al., 2002, Journal of Economic Theory 105: 408-434) bymeans of stochastic-dominance (sd) strategy-proofness and ontoness. Next,we study how much we can enlarge a domain to allow for the existence ofsd-strategy-proof probabilistic rules that satisfy ontoness and the no-vetoercondition. We establish that the domain of “convex" preferences is the uniquemaximal domain including a minimally rich domain for these properties.
