We consider the property of population monotonicity in the context of fair allocation problems in private good economies. It is already known that the property is compatible with the equal division lower bound. We show that if the equal division lower bound is replaced with no envy, the compatibility does not hold. We also show that the incompatibility persists even though no envy is weakened to no domination or -no domination. Hence, among the fairness criteria mentioned above, only the equal division lower bound is compatible with population monotonicity.This part of my dissertation thesis. I thank to my advisor William Thomson for many valuable comments. I also thank to Youngsub Chun and Yangkyu Byun for their comments. All remaining errors are, of course, mine.  相似文献

Procedures designed to select alternatives on the basis of the results of pairwise contests between them have received much attention in literature. The particular case of tournaments has been studied in depth. More recently weak tournaments and valued generalizations thereof have been investigated.The purpose of this paper is to investigate to what extent these choice procedures may be meaningfully used to define ranking procedures via their repeated use, i.e. when the equivalence classes of the ranking are determined by successive applications of the choice procedure. This is what we call ranking by choosing. As could be expected, such ranking procedures raise monotonicity problems. We analyze these problems and show that it is nevertheless possible to isolate a large class of well-behaved choice procedures for which failures of monotonicity are not overly serious. The hope of finding really attractive ranking by choosing procedures is however shown to be limited. Our results are illustrated on the case of tournaments.I am grateful to Hervé Raynaud and Jean-Claude Vansnick for stimulating discussions. Jean-François Laslier, Thierry Marchant, Bernard Monjardet, Xavier Juret and an anonymous referee made very helpful comments on earlier drafts of this text. Special thanks go to Patrice Perny who introduced me to the subject and to Olivier Hudry for his help with Slater orders. The usual caveat applies. Part of this work was accomplished while I was visiting the Service de Mathématiques de la Gestion at the Université Libre de Bruxelles (Brussels, Belgium).

Choice,freedom, and freedom of choice   总被引:1,自引:0,他引:1  
This paper argues in favour of a distinction between freedom and freedom of choice – a distinction that economists and political philosophers have so far either ignored or drawn wrongly. Drawing the distinction correctly may help to resolve a number of disputes in contemporary political philosophy and non-welfarist normative economics regarding the so-called preference-based account of freedom and the relevance, to judgements about freedom, of degrees of similarity between agents options. The paper begins by setting out three much discussed axioms for the measurement of freedom (of choice?) originally put forward by Pattanaik and Xu. It is suggested that the problems these axioms give rise to can be solved by distinguishing correctly between freedom and freedom of choice. The paper then sets out definitions of freedom, choice and freedom of choice, justifying these in philosophical terms and arguing their superiority to alternative definitions. Finally, on the basis of these definitions and with reference to Pattanaik and Xus axioms, it is shown that an agent can enjoy freedom without enjoying freedom of choice, and that she can enjoy an increase in one of these without enjoying an increase in the other. For their helpful comments on earlier drafts of this paper, I should like to thank Keith Dowding, Martin van Hees, Matthew Kramer, Marco Negri, Serena Olsaretti, Olof Page, Mario Ricciardi, Alan Ritter, Hillel Steiner, Kotaro Suzumura and audiences at seminars in Manchester, Palermo, Pavia and Oxford. I am grateful to the Italian Ministry for Higher Education (MURST) and the Italian National Research Council (CNR) for funding that facilitated the completion of the paper.  相似文献

We establish a strong impossibility theorem of a rational social choice that the proximity preservation (also called weak proximorphism WPX) and the diagonal surjectivity are logically inconsistent. The result is valid for finite or infinite alternatives, discrete or continuous. It generalizes the Baigent theorem, largely weakening his antecedent. For continuum set of alternatives, we clarify the notion of WPX by showing (1) WPX almost implies the continuity, (2) WPX is almost rigid. These observations raise the issue whether WPX is a natural condition for a social welfare function. A splitting reformulation of the proximity preservation which is weaker but rational is suggested.  相似文献

This study examined the association between a partners ability to eavesdrop on nonverbal cues and an actors feelings of rapport during interaction, as well as neuroticism and self-monitoring as moderators of this effect. Eavesdropping ability was defined as lower sensitivity to cues of the face, a source of overtly displayed emotions, relative to sensitivity to cues of the body, a source of leakage of covert or hidden emotions. Results showed that actors felt less rapport the higher their partners eavesdropping. High neuroticism actors were especially likely to feel worse about their interaction and themselves when their partners were good at eavesdropping. In both instances, the eavesdroppers nonverbal behavior seems to have mediated the associations to a small degree.Both authors contributed equally to this paper.

The paper derives a normative model for partial fiscal equalisation based on a number of axioms and makes special allowance for the existence of a specific fiscal need in the jurisdictions. A simple version of this idealised equalisation scheme relates net contributions to the equalisation funds to deviations of a jurisdictions gross income from average gross income and a jurisdictions specific needs from average specific needs. The theoretical model is then empirically tested for the case of the European Union using data from 1986–97. It is found that most restrictions of the model appear to hold, in particular, relatively richer countries contribute more and those with greater fiscal needs, approximated by the importance of the agricultural sector, pay less. However, in the EU, an adjustment of net payments to changes in the actual importance of the specific fiscal need for a country is lacking.The paper was presented at the CESifo Area Conference on Public Sector Economics 2001 in Munich and at a research seminar in Berlin. Thanks to the participants, Matthias Brückner, Johann Brunner, Jeremy Edwards, Friedrich Heinemann, Eckhard Janeba, Roland Strausz, and Alfons Weichenreider for helpful comments. Special thanks to an anonymous referee for many detailed suggestions. All remaining errors are our own.  相似文献

This paper reports exploratory data from a broader study that examines media representations of the voluntary sector in Canada. It specifically identifies the resources and organizational attributes of Canadian voluntary groups that appear to be important for receiving mainstream news coverage. The data identifies four sets of characteristics of more than 500 voluntary organizations: demographic variables, association type, noneconomic resources, and economic expenditures. These characteristics are examined in terms of their relationship to news coverage. The data suggest that area of activity is significantly related to the amount of media attention that organizations receive. However, the amount of media attention that an organization receives is most strongly influenced by its yearly budget. The implications of these findings are discussed in relation to both current debates about advocacy in the voluntary sector and important contextual developments that are transforming the communication environment in which charities and nonprofit organizations in Canada operate. We also draw comparisons to news coverage of the voluntary sector in other liberal democratic countries.  相似文献

This paper argues that recent struggles against neoliberal axioms such as free trade and open markets have led to a militant reframing of global civil society by grassroots social movements. It contests that this struggle to invest the concept of global civil society with transformative potential rests upon an identifiable praxis, a strange attractor that disturbs other civil society actors, through its re-articulation of a politics that privileges self-organization, direct action, and direct democracy. The paper further suggests that the emergence of this antagonistic orientation is best understood through the lens of complexity theory and offers some conceptual tools to begin the process of analyzing global civil society as an outcome and effect of global complexity.  相似文献

There have been few studies of the concept of double jeopardy as it pertains to the effects of gender and aging on occupational outcomes. This research examines the utility of this concept in the field of film acting, traditionally a gender-integrated occupation. The results confirm significant negative effects of being female and being older on the number of film roles received by actors and their average star presence. Moreover, the gendered effects of aging on the career opportunities of actors have diminished somewhat over time with respect to number of film roles but not with respect to star presence.  相似文献

This paper describes the present status of aquaculture activities in Dhaka City and its surrounding areas including the system of fish marketing and distribution and environmental and socioeconomic issues. Dhaka City contains over 10 million people and is expanding day by day. Demand of fish in the last 10 years has increased as a result of increases in population and income levels. The annual per capita consumption of fish is reported to drop by 0.5 kg since 1985. The reason for this decline is increased prices and decreased supply of fish. Fish supply to the city comes from catch in the rivers-estuaries and floodlands of Dhaka district, neighboring districts, imports from other areas and aquaculture in surrounding areas of the city. Considerable quantities of fish are imported from India, Myanmar and Thailand. Seasonal patterns are common both in supply and consumption of fish. Along with traditional rural household aquaculture, in recent years, urban and peri-urban aquaculture has also been popular. Three broad types of aquaculture activities are found in and around Dhaka City; these are polyculture of carp in ponds, monoculture of catfishs in ponds, and pen and cage aquaculture in open waters. The carp includes both Indian major carp and Chinese carp and some minor carp. The catfish group includes mainly Thai pangas (Pangasius sutchi). Tilapia (Oreochromis niloticus) is also widely popular among the farmers. The technology used for aquaculture is improved extensive to semi-intensive. Increasing demand for fish in the city markets has encouraged the expansion of peri-urban aquaculture with a corresponding increase in the proportion of farmed fish in the markets.  相似文献
