In an issue of the Harvard Business Review that explores the failings of capitalism, Michael Porter and Mark Kramer discuss in detail the value of positive social and environmental impact beyond simple profit.

"The recognition is there among sophisticated business and thought leaders, and promising elements of a new model are emerging. Yet we still lack an overall framework for guiding these efforts, and most companies remain stuck in a "social responsibility" mind-set in which societal issues are at the periphery, not the core.

"The solution lies in the principle of shared value, which involves creating economic value in a way that also creates value for society by addressing its needs and challenges."
