We show that Bayesian ex post aggregation is unstable with respect to refinements. Suppose a group of Bayesians use ex post
aggregation. Since it is a joint problem, each agent's problem is captured by the same model, but probabilities and utilities
may vary. If they analyze the same situation in more detail, their refined analysis should preserve their preferences among
acts. However, ex post aggregation could bring about a preference reversal on the group level. Ex post aggregation thus depends
on how much information is used and may keep oscillating (“flipping”) as one keeps adding more information.

In a general model of indivisible good allocation, S?nmez (1999) established that, whenever the core is nonempty for each
preference profile, if an allocation rule is strategy-proof, individually rational and Pareto optimal, then the rule is a
selection from the core correspondence, and the core correspondence must be essentially single-valued. This paper studies
the converse claim of this result. I demonstrate that whenever the preference domain satisfies a certain condition of `richness',
if the core correspondence is essentially single-valued, then any selection from the core correspondence is strategy-proof
(even weakly coalition strategy-proof, in fact). In particular, on the domain of preferences in which each individual has
strict preferences over his own assignments and there is no consumption externality, such an allocation rule is coalition
strategy-proof. And on this domain, coalition strategy-proofness is equivalent to Maskin monotonicity, an important property
in implementation theory.

Governments around the world combat inequality by means of group-specific redistribution. Some pursue redistribution that benefits groups, but also wish to avoid accentuating or even recognizing group distinctions. This poses a dilemma that they try to resolve by adjusting the category system used to target redistribution. There are three types of adjustment: accommodation (the multicultural approach), denial (the ideal-typical liberal solution), and replacement (a compromise). In replacement the targets of redistributive policies are constructed to avoid accentuation or recognition of inconvenient group distinctions, but still allow redistribution that benefits these groups. Replacement is increasingly in demand around the world because the disadvantages of multiculturalism are becoming apparent while denial is hard to sustain in the face of group inequality. The actual effect of replacement is little researched and less understood, however. Does it resolve the dilemma of recognition? Two examples–India and Nigeria–where replacement has been tried ever since the 1950s cast doubt on its viability. 相似文献
