Dynamic multidimensional assessment of sustainability at the macro level: The case of Austria

This paper explores the issue of sustainability at the macro scale employing multi-criteria decision aid (MCDA) methods. The incommensurability of values and the essentially multi-dimensional and dynamic nature of sustainability challenge the use of composite measurement indices. This determined the choice of MCDA methods. Austria was chosen as a case study, due to the wide availability of data, especially on indicators of strong sustainability. The structure of the multi-criteria problem comprised the evolution of different sustainability dimensions over time. The process for selecting criteria included a critical assessment of institutional sustainability agendas (UN, EU and Austrian Government) and theoretical recommendations.After an assessment of MCDA methods, the NAIADE method demonstrated the most suitable properties for sustainability assessment. The application of this outranking approach was undertaken in three separate settings: long-term from 1960 to 2003, medium-term, 1970-1995, and short-term, 1995-2003 with varying numbers of criteria. The response of results to the addition of evaluating criteria and periods was tested. The degree of credibility for accepting preference relations was also employed for sensitivity analysis.According to the results of long-term and medium-term assessments, especially in the weak sustainability setting, sustainable progress is taking place in Austria. In the short term, in the stronger sustainability setting and, especially as the number of criteria increases, more incomparable periods appear and trends are less determined. Moreover, it is shown how results crucially depend on the methodological choices.This is one of the first applications of the multi-criteria tools to the dynamic analysis of sustainability at the macro scale.     

Reassessing retiree benefits: the new challenge

For most employers, uncertainty about the future shape of the U.S. health care system, rising health care costs and FAS 106 accounting rules mean it is important to manage retiree medical costs. Survey data shows many employers are taking steps to manage their future retiree health care costs. These steps include reducing benefit levels, introducing service-related contributions and introducing managed care elements to retiree medical plans.     

Quotas and the second best

This note makes two observations about trade restrictions on subgroups of commodities. First, unlike tariffs, unalterable quotas provide no second-best justification for general restrictions. Second, the optimal allocation of intra-subgroup trade depends on the form of restraint imposed.     

本土化和全球化并存下的企业责任和公司治理(英文)

近几年,公司治理日渐成为新的研究热点,吸引了各界广泛的兴趣。从传统意义上说,公司治理研究的是不同国家背景下的企业内部决策权分配的问题。本文却旨在超越传统观念,试图将公司治理概念与日益凸显的全球化统一起来。 为更好地探讨新的公司治理形式,我们粗泛地把它定义为：多重参与者影响下的、聚焦于企业合法利用国内外资源的企业战略决策。此定义带有与“战略方向”意义相一致的内涵。两者均承认治理决策对企业战略方向有影响,后者决定了企业和股东能否获得好的投资回报。 在战略管理领域,“公司治理专注于解决公司内部决策权分配的问题”（Gollis 和 Montgomery,1997）是一个被广泛接受的观点。传统观点认为,企业决策权的制定应局限于对企业资源有明确主张的内部利益相关者,而今,越来越多的人认识到企业外部的利益相关者也应获得企业决策权的合法权（Hill 和 Jones,2007）。尽管拓宽后的公司治理概念（也就是说,超越企业边界的社会群体与从中选举产生的董事会影响企业资源配置的决策权）常被归入企业社会责任范畴;可一量考虑到企业社会责任涵盖经济,生态和社会等内容,公司治理概念的外延也随之变得广阔起来——它要解决的问题不仅包括如何为公司股东聚焦财富,同时也包括如何对自然与社会环境施加直接的影响。 让我们把基本假设阐述得更清晰些。首先,政府的三个层面,即联邦、州（或省）及地方,对公司治理的影响是有效且关联的;其次,国际关系的描述性效用（可识别为各国基于企业资源决策的竞争性互动）对公司治理的影响越发显著。考虑到影响战略方向与绩效的国际层面互动,我们假设,除了三个传统的政府层面外,还存有重要性不弱于前者的第四层面（称其为超国家层面或许更恰当）。在此层面上,有众多影响企业治理的参与另两种组织（跨国公司、非政府组织）进行了详细讨论。 很明显,跨国公司、非政府组织是影响公司治理的新要素,它的出现已得到文献详细论述（Dah 和Jeegen,2003）。随着非政府组织影响的延展,要掌握当代公司治理的演化,我们需对“全球”和“本土”等几组概念进行扩展。举例而文言主,从“本土”视角看,拉丁美洲仅意味着地球的某一特定方位,如果拉丁美洲真的与世隔绝,用“本土”描述这一时空统一体当然是正确的。然而,由于快速沟通的实现,尤其是互联网的出现,只要点击鼠标,“本土”即刻成为了“全球”。因此,“本土”和“全球”合而为一是全球化的结果。 非政府组织领导者非常清楚全球性的根本改变,他们利用这种改变来增强自己的优势,并依据即定目标最大地发挥该组织的影响力。利用互联网的信息传播或是CNN的新闻报道,基于很低的成本,“绿色和平”组织可在几秒内把一件地区性小事（村落传闻）变成全球性大事（国际流言）。有鉴于此,“本上”不仅仅是方位,它还是发生在这个方位上的所有事件,而这些事件能迅速转化为国际性焦点。无疑,本土和全球已融为一体,我们也必须将他们视为一体。 为进一步阐明公司治理近几年已发生根本变化的观点,本文运用三个安全例来支持这种改变是如何在利益相关者试图影响公司战略方向的情况下发生的。案例一讲述执行墨西哥组装工厂计划的跨国公司回应关于外界呼吁其自主披露战略导向的故事。案例二描写的是沃尔玛在美国某社区建立分店的意图遭非政府组织与当地市民反对而最终落败的历程。案例三介绍多元化的利益相关者（政府、非政府组织、跨国公司、联合国等）如何通过国际制裁、国内立法和行业自治等手段以保护钻石产业免受战略性威胁。     

The effects of the international-domestic interest rate gap on US output

This paper examines how the relationships linking money to real output are altered when an international-domestic interest rate gap is included in the model. The results indicate that both the international-domestic interest rate gap and term structure exert a statistically significant effect on real economic activity. In addition, fluctuations in these variables contain significant information about future changes in real output. An interesting finding is that while the term structure dominates the international-domestic interest rate gap when estimating the entire time period, 1970:1–1996:4, the international-domestic interest rate gap clearly dominates in the more recent time period, 1985:1–1996:4.     

The Determinants of School Participation Rates: A Cross-Sectional Analysis for New South Wales and Victoria*

Using data from the 1976 Australian Census of Population and Housing, estimates of the influence of family income. labour market conditions, religious denomination, foreign origin, locality and teenage income on the school participation rate of various teenage groups are obtained. These results suggest that family income is the most important determinant of school participation. The effect of the level of unemployment upon school participation is only modest. In some instances the direction of its influence is contrary to conventional wisdom .
