Subject background and discussion: In recent decades, issues of human rights, labor and environmental change has been hot topics world wide, which also has influenced the financial market. More and more investors use socially responsible investing (SRI) screens when constructing their portfolios. One form of SRI screen is to choose companies that have satisfied employees. Existing theory says that employee satisfaction is an intangible asset to the firm that will positively affect a firm’s performance in the future. Intangible assets are often unrecognized by the market and thereby not incorporated in the stock price. The efficient market hypothesis has been studied and debated for several decades. Proponents of the EMH argue that all available information is incorporated in the stock price, thus it is not possible to systematically beat the market. However, EMH is controversial, since research has shown different results regarding the possibility to make abnormal return from various investing strategy. Research question: Is it possible to make abnormal returns by investing in a portfolio of worldwide firms with top scores on the SRI screen employee satisfaction? Purpose: The main purpose of this study is to examine investor’s possibility to make abnormal return with controls for multiple risk factors by investing in worldwide firms with top scores in employee satisfaction. One sub-purpose is to examine how the market values intangibles depending on the degree of market efficiency. Another sub-purpose of the study is to test two different portfolio weighting methodologies, equally- and value weighted, and observe the differences between them. Theory: This study deals with the efficient market hypothesis and the concepts of SRI, employee satisfaction, intangible assets and several risk-adjusted measurements. Method: We have chosen to perform a quantitative study with a deductive approach to answer our research question. We used a sample size of 696 firms based on “Great Place to Works”- lists of companies with high employee satisfaction to construct sex portfolios with different holding periods and strategies. These portfolios have been explored and tested significantly with both equally and value weighted methods. Result/Analysis: The study finds significant evidence of an average annual abnormal return of 3,66% and 2,43% for our main portfolio over the market for equally- and value weighted, respectively, using the three-factor model. When adjusting for momentum, thus employing the four-factor model, all the predictive variables still identify strong persistence in the abnormal return, with statistical significance. Conclusion: The results show that it is possible to make abnormal returns, during the observed time period, regardless of the weighing methodology, although the equally weighted received higher abnormal returns. Thus, the market efficiency appears to be in weak form and does not fully value intangibles.

En prenant l’exemple des entreprises pétrolières multinationales, cette thèse tente de clarifier l’état actuel du concept de responsabilité sociale des entreprises, qui, d’un point de vue juridique, relève du « soft law», et à dessiner la frontière entre le « hard law » et le « soft law», dans le but de mettre en lumière la différence entre les fonctions de ces deux types de droit et de dissiper les attentes irréalistes envers le concept de responsabilité sociale des entreprises. S’alignant avec cette logique, les contextes de la responsabilité sociale des entreprises ont d’abord été explorés, y compris l’évolution et les controverses autour de ce concept, ainsi que les instruments qui le sous-tendent et le mettent sur un pied solide, lesquels représentent certaines caractéristiques communes (diversité, flexibilité, inclusion des valeurs pionnières, etc.) pour être acceptés et engagés par les entreprises. Par ailleurs, a aussi été analysée la tendance au durcissement des règles nationales en cette matière, qui peut être constatée dans les pays développés et dans certains pays en développement. Puis, trois sujets, à savoir l’environnement, les droits de l’Homme et la lutte contre la corruption, ont été choisis et traités, pour, d’une part, exposer comment le « hard law » agit sur eux, ses faiblesses tant dans les pays en développement que dans les pays développés, et ses effets sur les performances réelles des entreprises pétrolières multinationales, et, d’autre part, déployer la contribution de la responsabilité sociale des entreprises sur ces thèmes. Enfin, les dynamiques de la responsabilité sociale des entreprises ont été recherchées. Certaines parties prenantes, comme les gouvernements, les investisseurs socialement responsables, les concurrents ou les ONG, ont un potentiel conséquent pour pousser les entreprises pétrolières multinationales à adopter une approche socialement responsable, tandis que certaines parties prenantes, comme les consommateurs responsables, restent un facteur faible pour la prise de décision de ces entreprises. / Examining the example of multinational oil companies, this article tries to make clear the actual situation of the concept of corporate social responsibility, which from legal perspective belongs to soft law, and to draw a line between hard law and soft law, aiming to highlight the difference in functions of these two laws and to dispel unrealistic expectations of corporate social responsibility. Along these lines, this article firstly explores the context of corporate social responsibility, including its evolution, controversies around it, and the underpinning instruments that put it on a solid footing. These instruments represent a couple of common characteristics (diversity, flexibility, inclusion of pioneer values, etc.) that make them accepted by companies as commitment. Furthermore, both developed countries and some developing countries have seen a trend to strengthen national-level rules in this area. Secondly, three subjects, i.e., environment, human rights and anti-corruption, are selected and analyzed to show how hard law functions, its weaknesses in both developing countries and developed ones, and its effects on the actual performance of multinational oil companies, and also to explore what contribution the corporate social responsibility can make. Finally, the dynamics of corporate social responsibility is discussed. Some stakeholders, such as government, socially responsible investors, competitors and NGOs, have great potential to push multinational oil companies to adopt a socially responsible approach, while some other stakeholders, such as responsible consumers, remain a weak factor in the decision-making of these companies.

D’essence interétatique, le droit international public semble fermer ses frontières à toute responsabilité des entreprises transnationales. Cette imperméabilité à la reconnaissance d’une responsabilité juridique per se des pouvoirs économiques globaux n’a cependant pas empêché l’ordre international d’être réactif et d’évoluer en douceur. Face à l’apparition de plusieurs scandales liés à de graves violations des droits de l’homme, notamment dans le cadre des chaînes d’approvisionnement globales, il n’était plus concevable pour l’opinion publique de laisser les entreprises transnationales profiter du vide juridique existant. D’un cafouillis normatif émerge une régulation globale fortement imprégnée par le mouvement de responsabilité sociale des entreprises (RSE). Cette institutionnalisation de la RSE s’appuie sur plusieurs instruments normatifs parmi lesquels les principes directeurs des organisations internationales occupent une place centrale. Ces principes ont vocation à guider les actions des entreprises indépendamment de leur localisation géographique par le biais d’une sorte de toile normative uniforme pour tout le globe. En revanche, la mise en œuvre de cette régulation globale de la RSE n’est possible que par les pressions des acteurs sociaux (société civile et marché) qui tendent à promouvoir la responsabilité des entreprises et facilitent ainsi la transformation de la nature de ses normes. Des normes d’origine privée tendent progressivement à devenir une valeur incontournable dans la gouvernance des chaînes d’approvisionnement globales. En intronisant la RSE dans les relations contractuelles, cette gouvernance signerait l’avènement de nouvelles formulations de la RSE. Cette normativité nouvelle et innovante entend dès lors combler l’espace normatif inoccupé par les États. / Destined, in essence, to regulate interstate relations, public international law seems closed to the idea of recognizing liability of transnational corporations. However, this imperviousness to recognizing legal responsibility per se of global economic powers has not prevented a soft evolution of the international order. Following several scandals related to violations of human rights, some in the context of global supply chains, civil society could no longer allow transnational companies to take advantage of the existing legal vacuum. As a result, a global regulation strongly influenced by the trend of corporate social responsibility (CSR) emerged from a normative muddle. This institutionalization of CSR is based on several instruments, including guiding principles on Business and Human Rights which occupy a central position in this regulatory trend. It is intended that these principles will apply as a uniform, global normative canvas. Therefore, they should guide actions of companies regardless of their geographic location. The implementation of this CSR global framework is possible due to substantial pressure exerted by non-governmental actors, such as civil society and the market. These actors seek to promote CSR and facilitate the transformation of this regulation. Particularly, private standards are playing an increasingly important role in the governance of global supply chains. By establishing CSR in contractual relations, this governance would mark the advent of new regulatory tools which seek to fill in the public law gaps.

This thesis brings together two responses to the question ‘how can the law extend the timeframe for environmentally relevant decision-making?’ The first response is drawn from the context of institutional investment, and addresses the timeframe and breadth of environmental considerations in pension fund investment decision-making. The second response is related to the context of public environmental decision-making by legislators, the judiciary, and administrators. Three themes underlie and bind the thesis: the challenges to decision-making posed by the particular temporal and spatial characteristics of environmental problems, the existence and effects of short-termism in a variety of contexts, and the legal notion of the trust as a means for analysing and addressing problems of a long-term or intergenerational nature. These themes are borne out in each of the four substantive chapters. Chapter III sets out to demonstrate the theoretical potential of pension funds to drive the reduction of firms’ environmental impact, and, focusing particularly on the notion of fiduciary duty, explores the barriers that stand in their way. Chapter IV provides a practical application of the theoretical recommendations outlined in its predecessor. It provides a framework outlining how pension funds might implement a longer term, more sustainable approach to investing. The second half of the thesis, operating in the context of public environmental decision-making, is centred upon a particularly poignant legal notion with respect to the environment and time: the concept of intergenerational equity. Just as the first half of the thesis deals with the timeframes relevant to investment decision-making by pension funds within the bounds of fiduciary duty, largely a private law affair with public implications, the second half of the thesis is concerned with the principle of intergenerational equity as a means for extending the decision-making timeframe of legislative, judicial and administrative decision-makers. As previous analyses of the concept of intergenerational equity provide little insight into its practical implications when applied to particular factual situation, Chapter V sets out the structure of the principle of intergenerational equity as revealed by case law. Chapter VI brings together the issues from the first three papers by conceptualising intergenerational equity in resource management as an issue of long-term investment. Long-term environmental decision-making faces many obstacles. Individual behavioural biases, short-term financial incentive structures, the myopic pressures of the electoral cycle and the tendency of the common law to reinforce the (often shorttermist) status quo all present significant barriers to the capacity of both private and public decision-makers to act in ways that favour the longer term interests of the environment. Nonetheless, this thesis argues that there is reason for hope: drawing upon the three themes that underlie all of the substantive Chapters, it articulates potential legislative changes and recommends the adoption of particular governance structures to overcome barriers to long-term environmental decision-making.
