Pareto efficiency in multiple referendum

We consider situations of multiple referendum: finitely many yes-or-no issues have to be socially assessed from a set of approval ballots, where voters approve as many issues as they want. Each approval ballot is extended to a complete preorder over the set of outcomes by means of a preference extension. We characterize, under a mild richness condition, the largest domain of top-consistent and separable preference extensions for which issue-wise majority voting is Pareto efficient, i.e., always yields out a Pareto-optimal outcome. Top-consistency means that voters’ ballots are their unique most preferred outcome. It appears that the size of this domain becomes negligible relative to the size of the full domain as the number of issues increases.     

European Public Perceptions of Food Risk: Cross-National and Methodological Comparisons

This article presents a comparative study of public perceptions of food risk across 25 European member states. A secondary data analysis is conducted on a Eurobarometer survey fielded to nationally representative samples in 2005. The survey included closed questions as well as free associations to map risk perceptions. Taking a quantitative approach, we find that people in a majority of European countries express similar levels of concern about food risks. However, outside this majority a North-South divide is evident, with the Northern countries worrying less than the Southern countries. Multilevel modeling shows that cross-national differences in individual respondents' level of worry are in part attributable to shared country effects and to generalized risk sensitivity about a range of personal risks. On the underlying structure of food risk concerns, factor analysis points to three dimensions described by groupings of risks related to adulteration and contamination, health effects, and production and hygiene. A qualitative analysis of respondents' free associations about problems and risks with food identifies three major themes that are consistent with the quantitative results. However, the free associations also point toward greater cross-national diversity and to striking variations in the range and importance of food risks. Overall, the picture is of a public that frames food risks in a wider context of beliefs about the links between diet and health. We conclude with some implications for research on food risk perceptions in particular and risk perception studies in general.

地位焦虑、物质主义与炫耀性消费——中国人物质主义倾向的现状、前因及后果

通过对369份有效样本的层级回归进行实证检验,结果显示:中国人确实存在较高的物质主义倾向,且在人口统计因素上存在差异,其中男性比女性具有更高的物质主义倾向;家庭收入越高,物质主义倾向也越高;不同教育程度和年龄对物质主义倾向的影响不够显著.在中国社会转型背景下,人们的地位焦虑与物质主义倾向显著正相关;物质主义倾向与中国人的炫耀性消费显著正相关;物质主义倾向在地位焦虑与炫耀性消费之间起着中介作用.     

北京网络游戏用户策略对媒体融合的启示

网络游戏作为一种文化内容和经济利益相结合的传播载体,一直在用户的培养和维系上具有独特的观念和策略.传统媒体与新媒体的融合应该学习这种新的观念和策略来培养"用户".以北京市的部分重点网络游戏企业为案例,对媒介融合的"用户"观念进行分析,通过梳理其用户策略,提出应从用户关系、 内容生产以及体验创新三个方面加以借鉴和应用,打造一个能够拓展用户生产内容、 发展社交关系并且获得精细体验及人性化服务的平台.     

网络约车与出租车的竞争博弈研究——以平台补贴为背景

通过建立平台价格补贴背景下的网络约车与出租车的竞争博弈模型,分析平台价格补贴变化对网络约车与出租车的价格、 市场需求和利润的影响.研究发现,当平台给予消费者补贴较大而给予网络约车司机补贴较小时,网络约车定价可取得最大值;当出行前偏好搭乘网络约车的消费者较少时,在出行时刻真正搭乘的消费者数量远高于出行前的数量;而出行前偏好搭乘网络约车的消费者较多时,即使网络约车对消费者和平台司机维持高额补贴策略,在出行时刻真正搭乘的消费者数量却远小于出行前的消费者偏好数量.所以,传统的出租车市场不会在互联网迅猛发展、 平台高额补贴策略等冲击下彻底消失,其仍然会占有一定的市场份额.

Moments of order statistics of Topp–Leone distribution

We derive explicit algebraic expressions for both of the single and product moments of order statistics from Topp–Leone distribution. We also give an identity about single moments of order statistics. These expressions will be useful for computational purposes.
