The document summarizes Carroll's model of corporate social responsibility and discusses subsequent models that built on his work. Carroll's model proposes that CSR has four components: economic, legal, ethical, and discretionary/philanthropic responsibilities. Later models refined Carroll's work, such as Wartick and Cochran who defined CSR using three dimensions: principles, processes, and outcomes. The document also discusses criticisms of Carroll's model and alternative models proposed by scholars like Schwartz and Carroll that address some limitations through a three domain approach.
