This thesis builds on the literature of corporate social responsibility (CSR) communication. The following three chapters study the potential impacts of disclosing voluntarily negative information in a company’s own CSR communication within the contexts of pharmaceutical, textile and chocolate companies, respectively. Incorporating survey and experimental methodologies, these studies aim to help identify effective solutions for ethical issues by revealing the appropriate contexts in which companies can discuss them transparently and, thus, be rewarded for responding and acting in good faith and due diligence. Our results suggest that companies might benefit from voluntary disclosure of ethical issues if they also intend to disclose their specific actions for eliminating such infractions. Additionally, we highlight the role of public awareness in how negative information by the relevant stakeholders is evaluated. These studies reinforce the concept that acknowledging ethical issues would lead to higher levels of ethical behavior in business. / La siguiente tesis se basa en la literatura sobre comunicación de responsabilidad social corporativa (RSC) de empresa. Se analizan los posibles efectos de divulgación voluntaria de información negativa en la comunicación (RSC) en contextos de empresas farmacéuticas, textiles y de chocolate. Estos estudios tienen como objetivo ayudar a identificar soluciones efectivas a cuestiones éticas al revelar los contextos donde las empresas puedan debatir de manera transparente, y ser recompensadas por responder y actuar de buena fe y con diligencia. Los resultados sugieren que las empresas pueden beneficiarse de la divulgación voluntaria de aspectos éticos negativos si también divulgan sus acciones específicas para la eliminación de tales infracciones. Además, se destaca el papel de la sensibilización del público sobre como la información negativa se evalúa por las partes interesadas. Estos estudios refuerzan la idea de que reconocer problemas éticos conduce a niveles más altos de comportamiento ético en el mundo empresarial.

Corporate Social Responsibility (CSR) is one important response to the increasing amounts of criticism levelled at corporations. A number of studies have focused on CSR in a range of industries; however, some contentious industries, e.g. the gambling industry, remain unexplored. Mobilizing CSR in a novel setting not only enhances the knowledge of CSR and gambling, but also provides an overview of this industry itself. This thesis attempts to investigate three questions: to what extent does the gambling industry disclose CSR-related data, how is CSR understood in this industry and why does the gambling industry engage in CSR? This thesis provides a general overview of the international gambling industry and an in-depth investigation of Macao's gambling industry. The research design of the thesis employs mixed methods: content analysis and semi-structured interviews. The principal research is based on 49 interviews. This thesis advances three main arguments. First, it will be argued that there are relatively low volumes of Corporate Social Disclosure (CSD) and Responsible Gambling (RG) disclosure in the international gambling industry, which can be viewed as a legitimising strategy. Second, in Macao's gambling industry, it is argued that organisations in this industry tend to place a greater emphasis on positive social impacts, while obscuring such negative impacts as gambling addiction and health-related issues. Third, this thesis holds that organisations in Macao's gambling industry engage symbolically, rather than substantively, with CSR and RG in order to manage stakeholders' perceptions in an attempt to gain different sources of legitimacy and in turn to enhance its economic interests. In conclusion, the gambling industry does not entirely conform to the institutional environment, which poses a challenge to the organisational legitimacy literature. This thesis introduces a necessary caution into the discussions about the extent of CSD, CSR, and RG in this industry more generally.
