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

This article provides a comparison of three West European countries with five Central East European countries in respect of working time and the integration of work and family life. The countries are the Netherlands, Sweden and the UK in West Europe and Bulgaria, the Czech Republic, Hungary, Romania and Slovenia in Central East Europe. As well as providing an East–West comparison, the article also takes into account the differing institutional and policy contexts in the selected countries and the different routes to flexibility. A further aim of the article is to extend our understanding of the culture and values which underpin the organization of family and work in each country. Whilst there is a clear East–West divide, all eight countries demonstrate diverse routes to flexibility and different mixes of social policies and gender cultures which have lead to considerable differences in the integration of work and family life. 相似文献
