This unique supplemental text offers a well-structured and thorough introduction to corporate social responsibility (CSR). Author Brent D. Beal introduces the basic concept of CSR, briefly discusses the challenges of defining it, and summarizes important conceptual models. CSR is examined in the context of the perfect competition market model, market failure, and social dilemmas. Three different types of CSR—systemic, strategic, and philanthropic—are highlighted. Finally, arguments both for and against CSR are outlined and several conceptual frames are proposed. Readers are encouraged to think about what businesses should be responsible for in society and how a society's economic system should be structured, bounded, and ultimately, controlled. This text is appropriate for any business course in which the introduction of CSR would complement other course content.
