Impact of the FTSE4Good Index on firm price: an event study

This paper examines whether corporate financial performance is affected by public endorsement of environmental and social performance. Event study methodology, which relies on the notion of market efficiency, is used to examine the relationship between positive and negative announcements and changes in share prices or daily returns. Inclusion in and deletion from the FTSE4Good UK Index is used as a proxy measure for good (poor) corporate social responsibility. The abnormal or unexpected daily returns associated with an event are calculated and their significance tested. The results show a trend towards positive and negative announcements having the expected effects on daily returns. But these movements are not significant and the data do not suggest that a firm's presence on the index brings it any significant financial return for signalling its corporate social responsibility.

产权性质、市场竞争与企业社会责任行为——基于政治寻租视角的分析

无论是古典经济学理论、社会契约理论还是利益相关者理论,似乎都缺乏了一个重要的元素:政府行为以及政治、经济体制的影响,而只是将政府作为一个仅仅取得税收收益的利益相关者纳入我们的分析范畴,忽视了不同政治体制下政府构成了企业生存重要环境的特殊事实,这样的淡化直接影响我们对企业社会责任行为的实然理解。根植于西方社会的传统企业社会责任理论没有过多的考虑政府行为以及政治体制的影响,是基于其自身的制度背景与社会文化,它们是以高度自由的市场经济为基础,政府对经济(企业行为)干预很少,整个政治经济制度更加贴切新古典经济学的假设。而以中国为代表的新兴市场国家,政治经济体制改革和经济转轨使得制度环境对经济运行和企业决策有着重要影响,这为政治经济学理论的运用提供了制度基础,也为从政治经济学角度分析公司社会责任行为提供了研究机会。本文以我国2004年-2011年沪深股市的上市公司为研究样本,基于新政治经济学的寻租理论,研究了我国企业社会责任行为的寻租动机。研究的结果发现:我国企业社会责任行为呈现出明显的寻租倾向,而由于受到二元经济体制割裂的影响,相对于国有企业具有产权联系的先天优势,非国有企业社会责任行为表现出更为强烈的政治寻租倾向。实证研究同时也表明,产品市场竞争越激烈,企业寻租倾向越强。论文的研究构建了我国企业社会责任行为新的分析性框架,拓展了企业社会责任行为研究的相关文献。     

从循环经济视角看高职院校的专业长负责制

循环经济作为一种新的、科学的发展观,要求高等职业教育必须建立全新的适应循环经济发展的人才培养模式,在专业建设中凸显循环经济理念,用专业长负责制实现专业建设与社会需求的联通。以中国环境管理干部学院为例,以精品课建设为载体,从循环经济视角探讨了专业长负责制的推行,以及取得的成效。     

环境责任原则探析

环境法是一个新兴的部门法,对其基本原则的认定在学界观点颇多,没有形成统一的认识。环境责任原则在我国经历了一个从发展到完善的过程,体现了环境公平与正义的价值取向,反映了环境法可持续发展的本质特征,应该作为环境法的基本原则。同时,应通过法律制度的建设贯彻该原则,以发挥其对环境资源开发、利用、保护和管理等活动的指导作用。     

A revised calculation of the econometric factors α- and β for the Extended Exergy Accounting method

Extended Exergy Accounting (“EEA”) is a method to compute the space- and time integral of the primary exergy required to produce a good or a service: the extended exergy of a commodity measures its “embodied exergy”, including externalities (Labour, Capital and Environmental Costa). A crucial point of the method is the calculation of two econometric coefficients, commonly referred to as “α” and “β”,used to calculate the extended exergy equivalents of Labour and Capital respectively. In previous applications of the EEA method, these coefficients have been assigned approximate values estimated on the basis of global system considerations. In this paper, a novel procedure is described that leads to the calculation of “exact” values of both econometric coefficients, based on detailed exergy- and monetary balances of the Society to which the EEA is applied. It is shown that both α and β depend in a non-trivial way from the consumption patterns, the technological level and the life- and socio-economic standards of each Country. It is also shown that the values are substantially different for developed (OECD) and underdeveloped Countries, and representative samples of values are calculated and critically analysed. On the basis of these new model coefficients, the specific exergy equivalents of Labour (ee_L) and of Capital (ee_K) are calculated, and shown to differ from the values used in previous EEA calculations.

Competition between Populations in the Consumer–Producer Trophic Chain in a Closed Aquatic System

The functioning of a closed aquatic consumer–producer system with spatially separated links, with each link consisting of two species, is considered. Competition between the consumers (infusorians Paramecium caudatum and rotifers Brachionus sp.) feeding on a mixed algal culture (Chlorella vulgaris and Scenedesmus sp.) and competition between these algae under conditions of limited nitrogen supply are analyzed. It is shown that Scenedesmus algae have an advantage over C. vulgaris in terms of competitiveness, and their metabolic products have an adverse effect on reproduction in infusorians.
