新经济中的虚拟一体化组织

虚拟一体化是现代企业有效利用社会资源的一种常用组织形式。它不仅增强了企业的柔性和敏捷性,降低了交易成本和管理成本,而且其协调机制---隐性契约在克服因企业追求降低生产成本而提高资产专用性所引起的垄断租金和专用性准租金方面比纵向一体化和明示契约都具有优势。

Pricing-to-Market: Price Discrimination or Product Differentiation?

We employ a vertical differentiation model to examine the potential bias in pricing-to-market results when using export unit values aggregating differentiated products. Our results show that: (i) false evidence of pricing-to-market is always found when using unit values, whether the law of one price holds or not; and (ii) the size of the bias increases with the level of product differentiation. Our simulation results support those conceptual findings. Thus, some of the positive pricing-to-market results in the literature could be an artifact of the product heterogeneity embodied in unit values rather than evidence of imperfect competition.     

Progression,Stability, or Decline? Sociological Mechanisms Underlying Change in Specialization Among Birdwatchers

Using a panel of American birdwatchers collected in 1997 and 2002, we tested the extent to which birdwatchers progressed over a five-year period. The impact different career contingencies and life course events had on predicting change in birdwatchers' behavior, skill, and commitment was also examined. Findings indicated that although progression characterized some birdwatchers' participation, involvement by others was better characterized by stability or decline, which was true for each of the indicators used to measure specialization. Career contingencies and life course changes had only a moderate influence on predicting change in the specialization indicators over time. Support from family members and retirement were the best predictors of change in specialization.

经济转型期多元化经营的风险及对策

多元化还是专业化,这是企业发展过程中常遇到的问题,也是企业最困惑的问题之一。一般地,当宏观经济处于增长期,则行业发展趋好,行业竞争较弱,此时多元化经营比较容易成功;当宏观经济处于成熟期和衰退期,则行业发展趋势变坏,行业竞争加剧,多元化经营则难以成功。经济转型将使传统行业的发展趋势受到不利影响,从而加大多元化经营的风险。     

农产品纵向一体化运作模式初探

通过对国内外农产品运作的简要了解与分析,并结合中国广大农村的劣势分析与农产品的特性及其物流的特点,以及对我国农产品现有的供应链思想做了简单的探讨与分析,认为“小而精”的思想不适合农产品运作,提出了农产品“产加销一体化”这样的纵向一体化运作模式可能更符合中国国情,从而为农产品的有效运作提供一种新的思路。     

社会工作在基层治理专业化中的角色与功能

近年来,我国对居民社区建设的重视度不断提升,社区公共服务团队也在不断壮大,在国家政策的实施以及广大社区管理中,社区管理机构发挥着十分关键的作用。随着城乡居民生活水平的不断提升,传统的管理模式与基层治理手段已经落后,难以满足社区发展与民众生活的多元化以及专业化需求,因此,在社区治理中,融入专业性社会工作已经成为大势所趋。论文结合社会工作参与乡村振兴建设战略所进行的一系列工作,探究社会工作在基层治理专业化道路上扮演的角色,指出社会工作在基层治理专业化中的功能,阐明当前社区治理中的问题,探索促进基层社区治理可持续发展的道路。     

The determinants of the location of foreign direct investment in UK regions†

This article employs a database of over 2000 observations of Foreign Direct Investment (FDI) projects in UK regions. We analyse this data by means of various multinomial and conditional logit models in order to identify the major determinants of the location choices of these inward investments. Having controlled for the various characteristics of inward investing firms, the projects and the regions, our results suggest that existing regional specialization is the single most important determining feature of where inward FDI locates. In addition, London is seen to benefit primarily by the immigration of new investments, the majority of which are related to service sector activities.     

Does player specialization predict player actions? Evidence from penalty kicks at FIFA World Cup and UEFA Euro Cup

Penalty kicks are analysed in the literature as ‘real life experiments’ for assessing the use of rational mixed strategies by professional players. However, each penalty kick cannot be considered a repetition of the same event because of the varying background conditions, in particular the heterogeneous ability of different players. Consequently, aggregate statistics over data sets composed of a large number of penalty kicks mediate the behaviour of the players in different games, and the properties of optimal mixed strategies cannot be tested directly because of aggregation bias. In this article, we model the heterogeneous ability of players. We then test the hypothesis that differently talented players randomize over different actions. To achieve this aim, we study a data set that collects penalties kicked during shoot-out series in the last editions of FIFA World Cup and UEFA Euro Cup (1994–2012) where kickers are categorized as specialists and non-specialists. The results support our theoretical predictions.
