Corporate social responsibility emerged in the 1960s as companies faced increasing pressure to address harmful impacts of their operations. CSR involves voluntary commitments by companies beyond legal and economic obligations. It can be defined as accommodating corporate behavior to societal values and expectations. There are various approaches to CSR, including Milton Friedman's view that a company's only responsibility is to increase profits legally, and Archie Carroll's view that companies have economic, legal, ethical, and discretionary responsibilities. Arguments for and against CSR center around profit maximization, resource fit, and lack of accountability.
