La información no financiera y el desempeño financiero empresarial

This paper aims to validate the effects that sustainability reports have on the financial performance of Colombian companies. Through a panel data model and the information of 30 companies listed on the Colombian stock exchange for the 2012 - 2015 period, the impact of sustainability reports on the financial performance of this group of companies is evaluated. It is concluded that the size of the company and the number of environmental indicators have a positive effect on financial performance, while its antiquity causes the opposite.Este artigo pretende validar os efeitos que os relatórios de sustentabilidade têm no desempenho financeiro das empresas colombianas.

Has the CSR engagement of electrical companies had an effect on their performance? A closer look at the environment

Even though electrical companies attain a top ranking in the publication of CSR reports, they are often accused of 'green‐washing' due to their bad environmental reputation. The current economic crisis is testing their real CSR commitment more than ever, especially when this goes beyond its economic consequences. Based on a worldwide sample of electrical companies, we are going to study why companies are being socially responsible. We wish to know if it is due to the impact on the firms' performance or whether there are other motives (legitimation, improving their reputation) that lead companies to carry out these practices. We will also consider if it changes across the kind of CSR action considered. The results show that there is an economic justification beyond the socially responsible behaviour of the electrical companies. Additionally, most kinds of CSR action (community, diversity, corporate governance, product responsibility) are also carried out looking for economic rewards. However, the CSR actions oriented to the environment are mainly motivated by their need to improve their image and reverse their negative impact

Do Board's Corporate Social Responsibility Strategy and Orientation Influence Environmental Sustainability Disclosure? UK Evidence

The environmental implications of corporate economic activities have led to growing demands for firms and their boards to adopt sustainable strategies and to disseminate more useful information about their activities and impacts on environment. This paper investigates the impact of board’s corporate social responsibility (CSR) strategy and orientation on the quantity and quality of environmental sustainability disclosure in UK listed firms. We find that effective board CSR strategy and CSR-oriented directors have a positive and significant impact on the quality of environmental sustainability disclosure, but not on the quantity. Our findings also suggest that the existence of a CSR committee and issuance of a stand-alone CSR report are positively and significantly related to environmental sustainability disclosure. When we distinguish between firms with high and low environmental risk, we find that the board CSR/sustainability practices that affect the quantity (quality) of environmental sustainability disclosure appear to be driven more by highly (lowly) environmentally sensitive firms. These results suggest that the board CSR/sustainability practices play an important role in ensuring a firm’s legitimacy and accountability towards stakeholders. Our findings shed new light on this under-researched area and could be of interest to companies, policy-makers and other stakeholders

On the effectiveness of private transnational governance regimes - evaluating corporate sustainability reporting according to the Global Reporting Initiative

The increasing involvement of multinational enterprises (MNEs) in global governance has been both applauded for its potential to make governance more effective and criticized for lacking democratic legitimization. Hence we investigate the effectiveness of one transnational governance regime, corporate sustainability reporting according to the Global Reporting Initiative (GRI). We found that the GRI has been successful in terms of output effectiveness by promoting the dissemination of sustainability reporting, in particular among Asian and South American companies. However, the outcome effectiveness of the GRI is limited as reporting showed a rather uniform content across countries and sectors which does not reflect materiality considerations. As GRI reporting does not seem to have facilitated greater company–stakeholder interaction, its impact effectiveness is likely to be limited too

Contents and Determinants of Corporate Social Responsibility Website Reporting in Sub-Saharan Africa: A Seven-Country Study

Corporate social responsibility (CSR) in developing countries has recently received increasing attention, and scholars have pointed to the strong contextuality of CSR in the respective regions. Regarding the latter, however, sub-Saharan Africa has been scrutinized only marginally by academia. Moreover, empirical research on the impact of the institutional context has been scant, despite its attributed importance for CSR. Our article seeks to fill a part of this research gap by investigating CSR website reporting of 211 companies in seven sub-Saharan countries. The study’s aim is twofold: First, we identify to what extent sub-Saharan companies report on CSR and which contents they disclose. Second, by building on institutional theory, we investigate how the socio-economic and political environments influence CSR reporting. For this purpose, we examine the impact of country-level and company-level determinants. We find that the sample African companies’ CSR efforts focus strongly on local philanthropy and therefore differ substantially from Western CSR approaches. Furthermore, we evidence that GDP and level of governance standard positively affect CSR reporting. Our study contributes to the literature by empirically evidencing the contextuality of CSR in Africa and by explaining how specific country- and company-level determinants contribute to or hamper the development of CSR in developing countries

The impact of changes in stakeholder salience on CSR activities in Russian energy firms: a contribution to the divergence / convergence debate

This empirical paper examines the drivers underpinning changes to socially-responsible behaviours in the Russian energy sector. Responding to recent requests to contextualise CSR research, we focus on the changing set of stakeholders and developments in their saliency as reflected in corporations’ CSR activities. Based on interviews with more than thirty industry professionals, our findings suggest that Russian energy companies’ CSR is strongly stakeholder driven, and organisations adapt their activities according to their dependence on the resources that these salient stakeholders possess. We challenge the proposition that CSR in Russia arises from purely endogenous, historical, paternalism or neo-paternalism. We identify stakeholders that now shape CSR in the Russian energy sector, both endogenous (institutional and contextual forces relevant to the national business system) and exogenous (relating to the organisational field of the energy industry - international by nature). We thereby contribute to the convergence / divergence debate within CSR theory by demonstrating that both national business systems and the organisational field must be taken into account when analysing the forces that shape CSR strategies in any one country
