This book provides professionals, as well as students, with the understanding that Social Entrepreneurship and Corporate Social Responsibility (CSR) are now core business principles for sustainably. It encourages social entrepreneurs in their role as forerunners, in creating new business models that develop, facilitate or implement constructive solutions to social, cultural and environmental issues. At the same time, this book views corporate social responsibility as a means of challenging existing entities to realize and modify prior unsustainable and predatory business models; and to increase social, cultural and environmental accountability. By linking these two concepts, this book prompts a paradigmatic awakening, whereby the foundational driver of business creation and management no longer rests on profit maximization, but on improvement of the quality of life for society.
