This concise and self-contained book opens completely novel areas of research by directly implementing concepts from quantum physics into areas of social science.It constructs compelling arguments originating from fundamental concepts in physics and the philosophy of science, including key developments in economics and finance, then surveys the important work which has been performed to date through applying the formalism of quantum mechanics to decision making and finance.The book is accessible to graduate students and researchers in social science and physics, as well as avid interdisciplinary readers.This title is part of the Flip it Open Programme and may also be available Open Access.Check our website Cambridge Core for details.
