Tokenistic short-term economic success is not good indicia of long-term success. Sustainable business success requires sustained existence in a corporation's political, economic, social, technological, legal and environmental contexts. Far beyond the traditional economic focus, consumers, governments and public interest groups alike increasingly expect the business sector to take on more social and environmental responsibilities. Corporate social responsibility (CSR) is the model in which economic, social and environmental responsibilities are fulfilled simultaneously. However, there is insufficient empirical evidence that demonstrates genuine widespread (...) adoption of CSR in practice, and its underlying reasons. Though research in CSR has been rapidly growing, its commercial reality and implications need to be further improved if it is to inspire corporations to voluntarily adopt CSR. In the literature, Carroll's four-dimensional (economic, legal, ethical and discretionary) CSR framework offers a theoretical basis for developing an empirically based model to explain why and how profit-motivated managers take up CSR voluntarily. Our study has developed a structural equation model to identify the key factors and their interactions that influence economically motivated managers to take on voluntary CSR, and validate Carroll's four-dimensional construct. The results support Carroll's four-dimensional CSR framework, with the exception of the link pertaining to the relationship between economic and discretionary/voluntary responsibility. This characterises the economic reality that financial market-driven economic responsibility does not automatically translate into social responsibility. Nevertheless, the empirical results demonstrate that corporations can be led to engage in more voluntary CSR activities to achieve social good when appropriate legal and ethical controls are in place.
