John Ikerd spent the first half of his thirty-year academic career as a traditional free-market, neoclassical economist. He served on the faculties of four major state universities during his career: North Carolina State University, Oklahoma State University, the University of Georgia, and the University of Missouri. Growing concerns for the lack of ecological, social, and economic sustainability of American agriculture during the 1980s led to broader concerns for the lack of sustainability for American society in general. As an economist, Dr. Ikerd eventually came to understand that growing threats to ecological and social sustainability are rooted in the neoclassical paradigm of economic development, which is inherently extractive and exploitative, and thus, is not sustainable. Dr. Ikerd spent the last half of his academic career and much of his time since retirement developing and testing the concepts and principles of an alternative development paradigm, the economics of sustainability, which are elucidated in this book.
